How Much Weight Can You Lose With Phentermine?

General Phentermine Questions?
Check out the ultimate guide to phentermine weight loss pills!

Although phentermine is the most widely prescribed weight loss medication in the US, there is still a degree of confusion surrounding the drug with respect to how it works and what those prescribed it can expect in terms of effects and weight loss. A very common question stands, “How much weight can you lose with phentermine?” Here we explain how you can achieve long term weight loss success, by recognizing what phentermine can do for you and how you can make the most of your phentermine prescription.

Change Your Perspective

As with attempting to make any lifestyle change, the most important thing you can do to ensure that the changes you make are successful and permanent, is to change your perspective. The goal of any weight loss plan is to help you learn how to independently make informed choices with respect to the food you eat and the activities you chose to do, and phentermine is no different. Phentermine helps you to lose weight by reducing your appetite and increasing energy levels, and so, should be seen as a tool to help you establish a routine of healthy eating and exercise. The best way to make use of this tool while you have access to it, is to take the time to educate yourself about healthy choices, such as how to satisfy hunger more effectively with nutritious and delicious foods and how to discover the key to enjoying exercise solely for the pleasure of moving your body and feeling yourself getting stronger and healthier.

An important part of changing your perspective is to remove the word ‘diet’ from your vocabulary and recognize that the changes you make have to be sustainable for life. That is not to say that you need to feel like you are resigning yourself to a lifetime of eating rabbit food and 6am gym workouts. Instead, recognize that by making small changes now that you feel you will be able to stick to in the long term, you will be less likely to give up, and even less so when you begin to see big changes in your health and body which will motivate you to continue.

Follow the Doctors’ Orders

The best way to ensure you get the most from your phentermine prescription is to be informed about your choices while also being careful to follow the advice given to you by your doctor. In the same way that you should always disclose everything to your doctor about your lifestyle, medications you are taking, and other important factors, you should also expect that he or she informs you of everything you need to know about phentermine and your prescription. In this sense, both the doctor and the patient being fully informed means there is a better chance of success and less potential for confusion or problems with your phentermine prescription. We strongly encourage those taking phentermine to ask their doctor questions in order to educate themselves about side effects, dosages and what to expect, but another great way to find out more information is by participating in the Phentermine.com forum to seek support and share experiences.

It is also important to recognize that everyone is different; your prescription or dosage may be different to what you’ve had before or what another member of the Phentermine.com forum has been given, but by ensuring that you feel informed by your doctor, you can know that what you’re taking is the prescription best suited to you and your individual circumstances. If at any point you feel unsatisfied with the effects of phentermine, or have any worries or concerns about side effects, we would always advise you to consult your doctor before making any changes to how you take your prescription. Your doctor will base your prescription on what he or she judges to be best for you, but if you don’t feel that your dosage is sufficient, or perhaps that it is too strong, it is always better to seek your doctor’s advice in order to reach a suitable solution and ensure that whatever dose you’re taking works in the best way possible for you.

What to Expect

One concern for those taking phentermine, is that due to the limited amount of time (typically 12 weeks) that phentermine is prescribed, there is an urgency to lose as much weight as possible during this time. However, this is not the intended use of phentermine, as rapid weight loss is neither healthy nor sustainable. Depending on your lifestyle prior to taking phentermine and the changes you make once you start, such as if you greatly increase your water intake, it is often possible to lose several pounds in the first week as your body sheds water weight. However, the recommended weekly rate of weight loss is one to two pounds; this rate ensures that your body is losing fat and not precious muscle, which your body needs to retain in order to assist with fat burning, and it is a rate which is achievable in the long term once your phentermine prescription has finished. Furthermore, unrealistic expectations can lead to feelings of failure and more chance of giving up if those taking phentermine fail to appreciate that smaller weekly losses are healthier and are more likely to add up to big total losses.

Often when people lose weight too rapidly it is due to them placing unreasonable demands on their body and not following a healthy diet and exercise regime. Making changes which are too drastic such as following fad diets or working out to extremes every day may help you lose weight in the short term, but if any changes you have made are not maintainable for life, then your goal weight will not be maintainable for life either. Although there will be a finishing point for your phentermine prescription, there is no such finishing point for following a healthy lifestyle. In order to continue losing weight or to maintain the weight you have lost, you will need to be mentally and physically fit and strong in order to continue a healthy lifestyle once your prescription ends. It is only by ensuring that you have taken your time on phentermine to adopt healthy habits and learn healthier ways to live, that you will be able to avoid the yo-yo effect of regaining the weight you worked so hard to lose.

Phentermine is usually only prescribed for short periods due to the effects it can have on the body, both in terms of side effects and due to becoming less effective over time, as your body becomes used to the medication. One way to ensure that phentermine continues to work for you, is to combine your phentermine prescription with Phen Caps, the phentermine alternative recommended by Phentermine.com. Phen Caps can help enhance the effects of phentermine while you are taking it, or as you come to the end of your prescription. Like phentermine, Phen Caps help you to lose weight at a steady rate by suppressing appetite and boosting energy levels, so you will be able to continue with your weight loss journey even after your phentermine prescription has finished. To learn more about Phen Caps, click here, or to purchase Phen Caps, click here!

The most important thing to remember when starting your weight loss journey with phentermine, is that it’s YOU who is going to do all the hard work to lose weight, and phentermine is just a tool to help you get to where you need to be to be able to go it alone. This realization should empower you to take on your weight loss journey being the most informed and motivated you can be, ready to lose weight for life with the help of phentermine but with 100% faith in yourself that you can and will do this, because this is your journey and you decide where it leads.

  1. Just started taking phentermine yesterday. I am super excited about the life style changes I am making! I quit smoking 14 months ago and with that I gained 30 lbs. I am also knocking on 50 so weight lose has become hard and hard. My husband is also overweight so we are making the life style change together. Tonight we did the “before” pictures. Very hard to look at! But like I said to him WE CAN CHANGE THIS! And we will!!

    • Lori, I am in the same boat as you (quit smoking, gained 13 pounds and am late 40’s). How is it going for you now 3 months later? I started today and I am also tying in the 21 day fix workouts.

    • I just started on Phentermine 4/30/2017. I\’m so loving the energy that it provides and the ability to suppress my appetite. I\’ve also set aside my pre-portioned meal & snack containers and the pills will not let you over it you will feel the fullness. I weighed in @ 192 lbs. 5 ft. 7 1/2 in. tall.
      I\’m so excited about my weight loss journey and can\’t wait for my next visit at the end of May. Wish me luck as I wish you all good luck. We can do it you guys lets encourage each other and push forward. 🚵🚵🏀🏀⚽⚽🎾🎾🏊🏊🏉🏉🚣🚣 lets workout

  2. I have been taking Phentermine for 2 weeks and I have already lost 6.5 pounds:) Thats without exercising but I plan to include exercising ASAP.

    • Yeah I feel ya I’ve started walking. And it’s already such a big change as far as my diet! I’m going to make each and every healthy change a habit 🙂 So I figure in a week or two Ill start doing more than just walking a mile twice a week.. I don’t want to overload myself. And I think your doing the right thing! If you ever want to swap cool things to eat or any good beginner exercises let me know!

      • What mg. Are u taking.. I’ve been on mine and not seen any difference on my weight or do I feel any better and I don’t have any energy.. HELP

  3. Hi everyone I just started 3-2-14 so what side affects do everyone have and does it take your hunger away all day or just for a period of time.. I have got different moods and It takes my hunger away from morning all the way to 9pm but I don’t think that’s healthy at all..

    • I’m never hungry! But I take that as an opportunity to eat small portions of something very good for me,.. A long side of vitamins. Because you don’t want your metabolism to go to crap. 🙂

      • I just started taking phentermine on the 14th and I know it’s only been 4 days. But it hasn’t helped me feel less hungry. Any suggestions or ideas why that might be?

      • I’ve been on it for 3 weeks and now I lost 25 pounds so far, but I have a lot more to lose

        • Did you exercise while taking it?

          • How did you do that i just started taking phen today

      • Today is my 4th day and ive lost 5 lbs… Im in love with this diet pill it gives me energy! not hungry i eat a small meal in the am n thats it untill the next morning 🌅 so yea i eat once every 24 hours… I also do 50 squats, tun in place for 5 min and do 70 jumping jacks yes it works 🙂

        • Yay! I’m pretty much doing the same thing… I literally have no appetite at all. I wake up and eat an apple with a few almonds in the morning and then basically force myself to eat a handful of carrots or grape tomatoes in the late afternoon. I’m a vegan anyway, so I’m used to eating healthy, but this diet pill gives me so much energy, I do at least 2 different work out videos a day and my dog and I walk a mile in the morning and a mile at night. I’ve lost 8lbs in 5 days. Can I ask what your starting weight was?

        • I started phentermine 37.5 on October 4,2016 and on October 3rd, 2016 I weighed 221.6 and today is October 10,2016 and the scale says 207.2. I go to the clinic today to see if it’s accurate and I also get a b12/lipo shot weekly. I changed my diet drastically and don’t eat any fried foods, I use mrs dash for seasoning that has 0 calories and water is the only thing I drink all day. I will start the gym this week cause I have done no exercising.

          • Hi, can I ask what your height is? And what your average weight should be?

  4. I started taking quismia pills last year. it helped me to drop from 245 to 197. my insurance covered almost the whole cost but decided to stop paying for diet pills in 2014 so my physician ordered phentermine which I am paying myself. my dose is only 15mg. but I have not lost anymore weight. I think maybe I need a stronger dose. we wanted to start off with lowest and see if I need stronger I have only been taking this pill for 2 weeks so after being weighed and talking to physician I will update. I have no side effects which is wonderful. I am small boned and 4feet ii inches tall and 64 years old.my ideal weight is 105-120 but I would be happy at 130.

  5. Started taking phen two days ago. Lost 1lb already. Most importantly I feel like a new person. I feel confident. My attitude is great. A small headache came last nite. Not drinking enough water. After I drank my headache was gone. One thing happened to me though. I forgot to eat because I’m not hungry at all. Not the least bit tempted. So remind yourself to eat and drink. The good thing is that because your not ravenous you have the ability and control to make healthy choices. Miracle phen. I love you.

    • I started taking phen Jan 28 2014. I weighed 171lbs as of today I am 148. I need to exercise more. I know I can do this. I’ve been having moid swings and nausea. .hopefully it passes

  6. I started this on February 4th and I just went back to doctor on March the 7th and lost 5 lbs.

  7. I started taking phentermine on 2/28/2014. I had lost 2 pounds as of 3/7/14.
    This is with me working out on the elliptical every day for 15 minutes a day, eating healthier and drinking a lot of water.
    I was hoping to lose at least 5 pounds a week. hopefully it starts picking up more

  8. I weighed 205 on March 1st, it’s March 10 and I weigh 198 🙂 Hoping to get to 125 eventually.

    • Did you reach your goal?

  9. I just started phentermine a couple days ago. I’m eating less. I have Type 2 diabetes so I have to lose weight. I’m hoping for a miracle. I’ll keep you posted

  10. I started on Phentermine on February 8; I couldn’t exercise for thr first week due to an injury, but as of today, five weeks in, I’ve dropped 10.5 pounds, which is about a third of the way to my goal of dropping 32 pounds of fat. I have to say I do a lot of exercise, and at high intensity, but as a strength athlete I was already used to exertion. The change I’ve made regarding exercise involves doing a lot more aerobic work. I won’t have the time to keep this up forever, but I already have a long term plan that will be easily sustainable. The main effect I’ve experienced from the medication has been the appetite control, which has allowed me to eat very lightly during the day, while enjoying a full meal in the evening; this has been the way I’ve lost weight in the past and although I’ll need to sustain this when I’m off Phentermine, I’m developing the habit and my stomach is shrinking.

  11. Hi everybody let me get real, I’m 51, 5’3, weight 272. Tupe 2 Diabetic I have been going to the gym for 2 yrs for 11/2 hours 4-5 times a week with next to no weight loss, but I’m strong and i can walk for miles without getting tired, which I love! Well I started taking Phentermine HCL 37.5 dose 2 weeks ago and I have lost WEIGHT! 14 pounds I know it a lot of weight to loss in two weeks, I’m on a high protein diet low in carbs, I see my doctor tomorrow will see what she says. Well side effects were bad for about 4 days but I’ve been cutting the table in half which does help. For me this is a good product and I will continue until my doctor day no more. I will keep you all posted to my Progress.
    Good luck guys! 🙂

    • I saw your comment and wondered how things were going for you? I am in your same boat and I am kinda worried about taking Phentermine. Are you still taking Phentermine? If not did you gain your weight again? I ask cause I got Phentermine 37.5mg and I just quit smoking and I was just diagnosed with type 2 diabetic. I am trying to get into a routine of doing step aerobics for 30 min. a day.
      I could use some advise…

  12. Hi! I have copd….I have taken phentermine, off and on, for two or three months at a time. I, at
    70yrs of age, have just found out I have congestive heart failure. Now, I take four different
    medicines, one of which is warfarin. I am not taking my phentermine, however, I really want to
    take it because it gives me energy, helps me to control my ravenous, gluttenous eating…it helps
    me maintain a decent weight….have any of you a similar situation? also, I am going to check out
    the new drug eliquis, which is suppose to be better than warfarin…Are any of you taking warfarin,
    or Coumadin…along with phentermine? please respond. thank you. Granny

  13. I started on Phentermine 3 days ago and i do notice im not as hungry and im making better food choices and smaller portions. When i feel more hungry after 6 pm i usually drink a bottle of water and that supresses the hunger.

  14. I started taking Phentermine 15 mg tablets on March 1, 2014. I weighed 155.2 lbs. As of today, April 5th, this morning I weighed 141.4 lbs. My goal weight is 130; I hope to reach my goal by May 30th. I have no desire for the cookies, ice cream and other foods I use to crave. I try to eat healthier and plan to start exercising next week to gain more muscle and reduce the fat. My old dress size was a 16; currently wear a size 10. My pant size was 14; currently wearing a size 8. I am really, really happy with the results and I have had no side effects.

  15. I started April 8, 2014 and today is April 11, 2014. I lost 10 pounds with lots of exercise. I drink a lot of water and high protein. I just eat crackers when I need a carb fix. I started at 190 and down to 180. I’ve lost 30 pounds in 30 days many years ago. So I’m hoping to do the same again.

  16. Had both of my hips replaced and have not moved much in the last few years. Went to the doctor yesterday to talk about weight loss. I’m 60 years old and am being treated for high blood pressure. Started taking 37.5 mg of Phentermine today and am impressed. Hope the energy and appetite suppression continues though out the 3 months.

  17. Am 239 my idea weight is 150 I start taking phentermine today let’s see what happen. Wish me luck

    • How much have you lost

  18. I just started Phentermine 37.5mg yesterday. I feel pretty good, but couldn’t get much sleep last night. I’m hoping that improves because today I’m dragging and feeling a bit nauseous. I’m 5″7″ and weigh 256. I have never been this heavy.

    • How have you made out? Our stats are very similar. I just started taking phen 37.5 last week.

  19. hi today is the first day i took it, and hope to see some progress during this step to my success.. Did you change the way you eat or you just took the pill.

    • Hi there, Thanks for the comment! 🙂

      Yes, you definitely want to change the way you eat and introduce some moderate exercise; this is very important! Click here to read an article of ours that covers all of this information, I think it will give you some great insight!

      Let me know if this helps or if I can help you with anything else,

  20. Hi everyone,
    On May 13, I went to the doctor and I weighed 262 pounds (I’m 36 yrs old and I am 5’4). My dr was seeing me for a sinus infection and said we needed to talk about weight loss ASAP. So I went to her and started taking Phentermine on June 3, 2014. I had lost 5 pounds so I weighed in at 257 pounds. My dr was adiment that I also do a low fat diet along with the pills. I had used weight watchers before and had good results so I started weight watchers and phentermine. This week, September 3, I anticipate my dr to take me off the pills. I currently weigh 225 ( 32 pounds lighter) and I love to exercise ( 5 times a week). I don’t go crazy, just Zumba on the xbox Kinnect or sometimes the elliptical for 30-40 mins a night. I am anxious about stopping the pills but I’m hoping the small changes I’ve made will continue. The only killer side effect for me…. Constipation!!!! UGH!! I also learned, don’t take it after 8 am or you won’t sleep 🙂

    • Hi Becky, Thanks for your comment 🙂

      Congrats on your weight loss so far, sounds like you’re doing a great job! Yes, when you stop taking phentermine, it can be scary to risk gaining the weight back, however it sounds like you are doing what is most important… a lifestyle change! That is the key to maintaining the weight loss long term. Also, you should really look into a non-prescription solution to maintain/lose more weight, like Phen Caps. They work just like phentermine however have no side effects and do not need a prescription, you can find out more about them by clicking here (as well as there 2 other new weigh loss products).

      You should also join our weight loss forum, we have a great community of people who discuss different issues with weight loss and phentermine, and they give great support! Check it out by clicking here. I hope this helps, let me know if you need anything else 🙂

  24. Started taking phen. On sunday. Haven’t set foot on a scale yet I’m waiting for Sunday to come around. I have noticed the loss of appetite and dry mouth, but nothing else. Wish me luck people. Starting weight 193 and goal is 130.

  25. I am 30 years old I started Phentermine 37.5 not even a month ago on October 18 it’s now November 6. I started with a weight of 201 and I am down to185.8, so far I have lost a total of 15.2 lbs. All my life I had problems with my weight and after I had my baby I gained so much weight and couldn’t lose it, no matter how hard I tried with exercise and diets. I am hoping to accomplish my goal of 130 lbs. My appetite and cravings have changed, also I have more energy. Thankfully my doctor prescribed me this medicine(along with a diet), without It I know I would still be stuck at 201.

    • That’s awesome Paloma.

    • What did you eat and did you exercise?

  26. I am 34 and I just started taking Phentermine 37.5 Oct.7th 2014 and when i went in for my check up on the 31st of Oct. I lost 28 lbs. Weighted in at 404 lbs on the 7th and on the 31st I went down to 376. My first week was rough but I wanted a change in my life so I stuck with the program and now I am enjoying life. Going to use this pill to my advantage while I can and keep going hard after its gone. After all its a life change and not a temporary change. This being said, stay with it and don’t give up on yourself. After all it’s up to us to lose the weight because we put ourselves there.

  27. I just started phen 37.5 last Wednesday, but was told to only take half for a few days to see how my body reacts to the meds. Started at 194, weighed today at 189. Had headaches at night for the first few days. I can’t get enough water…soooo thirsty! I’m excited to see how things go

  28. I started taking Phen 37.5 on 10/29/2014 haven’t had any side affects at all .. I was 263 when I started and as of 11/15/2014 I am now 245 lbs ..eating healthier and drinking water and walking ,, I’m excited to change my life style and look forward to my results ..

  29. I started Phentremine 37.5 with b12/b6 injections twice a month and lost 31lbs. I started at 202 and weigh 194 as of yesterday and counting. My goal weight is about 175-180. Side effects are lack of sleep. I take the pill between 7 and 7:30am but can’t get to sleep before 2am sometimes which isn’t good. I am in my 3rd month final 30 days of the pills will the Phen Caps still work for me?

  30. Started phen/pro 7/1/14. 350lbs. No side effects so far,currently 309 lbs. I don’t take it every day. I take it Mon-Fri. Break on the weekends (when I’m more active anyway and use this time to practice self control ) then back on at the start of the week. Lost 20 lbs in the first 2 weeks, then steady down every week after. I didn’t gain it in a short time so I’m pacing myself and my body seems to be responding well to taking it longer term. I’m 46 btw, enjoying feeling better and being more active! Good luck everyone, love yourself!

  31. I have been on phentermine 37.5 for 1 week an so far I have lost 10 pounds, I started out at 131 and am now 122 an the dr gave me the goal to get at 116 for my height I am 5’3 so was a little over weight for my height but I’m not far from 116 hopefully I should get their soon wish me luck (:

    • Hello,

      just curious on how much you weigh now? I am starting my pills and diet tomorrow. We are the same weight that is why I was being curious.

      • Hi I just started Phentermine today. Jan. 6, 2016. I currently weigh 210lbs. My highest weight was 220lbs. Hopefully this helps suppress my appetite since I’m an emotional eater. I always have to snack on unhealthy things. I’m also addicted to sugar and junk food. My goal weight is 150lbs since I am 5’4 inches tall. I will be SO excited to just hit 200lbs. I see everyone else having great results so I’m praying the same goes for me with little to no negative side effects. I will update soon. I have another Doc appt in 2 weeks. Wish me luck!

  34. Started phen jan7 2015 220 weighed in today jan23 2015 21 cant wait to see my self out of the 200 eds lol

  35. I started taking Phentermine 3 days ago and I\’m already down 6.5 lbs I\’ve increase my water intake drastically.

  36. I started taking Phentermine 37.5 on Feb 1 2015 && today is Feb 9th ..the first day I started out with the whole pill and felt horrible I felt so weird and nausea all day I even vomited my guts out I felt dry mouth and just SICK !! I figured it was bc I took the whole pill instead of half the pill the first couple days as the doctor suggested.. So the next day I took only half and I felt soooo much better no appetite mainly and dry mouth but drank tons of water to help with that. And I continued half pill for 5days then started the whole pill again and I felt amazing I had to get my body used to all the caffeine bc I never consumed caffeine prior to the pills… But never the less I started out 190 and today I am 185 so I lost 5lbs in a week I do 1 hour cardio 4-5times a week and I hardly eat bc I\’m not hungry I make myself eat but can never eat all … I also lift weights and I am doing a 30 day Ab Challenge as well.. I can definitely tell a difference in my clothes my goal is to get to 160-165 I hope to be in the 170s before March 1 but we will see

    • Great work Latosha, keep it up!! 🙂

  37. I just started taking \”Phentermine\” 2-24-2015
    And also it\’s 30MG which my doctor should have NEVER put me on. (Which I will tell you why, here in a few) back five years ago: I was on some meds; which made me gain over 120 lbs I did; every thing you could think of. The weight just would not come off.

    At that time I was up to 215 lbs
    And before- I started taking that drug (depoka)
    I was at 92 lbs my doctor then put me on a pill that is very close to the Phentermine. I lost some weight with the pill he put me on. Which I went down to 180

    I then got sick with my pancreas and caused me too lose another 80 lbs in three months.
    Now, here\’s why- my crazy doctor should not have put me on this. I am scared too gain too much weight and lately. I\’ve been loving food a little too much. I called for a pill- that could block-out from me eating so much. And this is what he put me on.

    My weight is at this moment 116 due to me eating way too much. This med- is for people 100lbs overweight. Well, my question is. How long would it take me to get back to my 92lbs?

    • You currently weigh 116 lbs and your doctor put you on Phentermine? Were you wanting him to give you something to help you get back down to 92 lbs? Either way, sounds pretty drastic. Why not just exercise and eat healthy and count calories? Phentermine is suppose to be prescribed for obesity or those in jeopardy of becoming obese.

      I lost 17 lbs in a month on Phentermine and that seems to be pretty close to typical, some lose more and some lose less based on what I\’ve read. But if you are already a healthy weight, I\’m not sure how long it will take to lose, as sometimes the body will tend to hold on to the weight, meaning you\’ll plateau if you lose too much too fast or are at risk of becoming underweight.

  38. I am on 50 MG of Topamax & 37.5 MG of Phentermine which I started on 3/16…… it is 2 days later and I have lost 4 lbs. I literally have NO appetite, but I do force myself to eat 3 small meals consisting of yogurt, fruit, salad, Luna Bars, and lots of water!!! My Doctor will see me monthly for weigh in checks, and blood work every 3 months. So far I have no side effects. I am not obese, but do need to lose about 50 lbs to be at a healthy weight. It seems to be a good combination for me.

    • Hey MaryLynn, well done on the weight loss and we’re glad you’re feeling good on the phentermine and topamax combination. However, it really doesn’t sound like you’re eating much. We realize it’s hard when you have no appetite, but barely eating and also not eating much of a range of foods means that your body isn’t performing at its optimum, so your metabolism will slow down and you’ll find it hard to lose weight in the long term. This article explains more about why such extreme appetite suppression isn’t such a good thing: https://www.phentermine.com/blog/phentermine-suppress-my-appetite/ You should probably get some more appetite back over the next few days and weeks, but we really do urge you to eat more of a variety of foods, vegetables, protein, healthy fats, fiber etc.
      Good luck!

  39. I started taking Phentermine 3_21_15
    I have experienced the dry mouth side effects, but nothing else. I started at 188.3 and my goal is 150, prayerfully with my continued exercise regiment, and my low carb, high protein diet I will reach my goal.

  40. Started Phentermine 37.5mg on 3/19/15. Have lots of energy and very little hunger. I paired this with a program I have done before that I knew worked I just did\’t make it my way of life, like I should have. This medicine just gave me more will power, so I can eat a smaller amount. I do have two snacks during the day. I am not on the strictest phase of Atkins, I do have some carbs from berries and cottage cheese. But I feel like its a plan I can stay on long term. Then one day when, because I will get to my goal weight of 140. I will add a few things back in finding the right carb limits to keep it off. I also have Hashimotos Thyroiditis which has always been hard to find the right dose, even now. My starting weight was 240 and now I weigh 225. That\’s 15 pounds in alittle over two weeks, I know it will slow down some like it did with Atkins alone, but my clothes are fitting loser and I have loads of energy and feel great.

  41. Hi everyone I just started Phen 37.5mg on 3/30/2015! My doctor prescribed them because I was 185 when I weighed in…which worried her because I\’ve never been this big!!! So far I\’ve have so much more energy, dry mouth which make me drink lots and lots of water!!! I\’m never hungry and even when I attempt to eat I feel sick

  42. I\’m starting my weight loss journey! Im going to succeed! I have to keep telling myself these things. I want to be heathy. I want to be a better mother and wife. My family deserves a mommy who isn\’t so over weight that she can\’t enjoy the simple things in life like going to the park!!!!
    Anyways..went to the doc on 4/1/15 and weighed in at 288lbs. I was shocked. I am heavier now then I have ever been. Not even with either one of my pregnancies!!! This is not the life I was meant to live. My doctor recommended a few different products and I finally decided on Phentermine. She gave me my prescription and I have started it today, 4/3/15. She said she will only prescribe for 6 months. She wants me to come in for a follow up at 3 months.
    I have made a few changes over the last couple weeks in the right direction. I haven\’t had a sip of pop (coke was my weakness) in nearly 2 weeks. I have also started walking at home with the family for at least 20 minutes a night and a few days a week on my lunch I will walk with a coworker! It\’s great to have such a fantastic support system.

    I NEED TO CHANGE! I am the only one who can control my destiny. I\’m to young to feel this old!!
    24yr. 5\’6\”. 288 on 4/1/15.
    I will update weekly. (I am only weighing myself once a week!

    • Hey Stephanie,

  43. Hello all,
    I started taking Phentermine April 1st. Since then I have lost 4 pounds which I must say has to be water weight since I\’m running to the bathroom every 13 minutes. Kinda annoying. That\’s the only side affect. My previous diet which was Meal Replacements shakes I still force even when I\’m not hungry because I know the consequences. And i run a mile a day and exersice. My only thing is my doctor didn\’t tell me it was only a 12 week step. I am very much over weight I\’ve always had issues. I\’ve been emotionally eating for about a year now which has put me at an all time high of 277 pounds And I\’m 5\’3. I\’m 29 years old. I wanna know if this is actually the cut off of 3 months I wanna get to a normal weight I know in 3 months I still won\’t be at my goal not even near. I need to loose 100 + pounds. What tips do you have for this should I look into lapband?

    • Hey Kay,
      I think it’s important to take it one step at a time, so take these 3 months as your opportunity to learn better habits for life. If then, you and your doctor think that more phentermine, or surgery, or other options are your next step, then it would be better to wait until that time to consider it. In the mean time, you can make the most of your phentermine by following these tips set out in a handy schedule: https://www.phentermine.com/blog/best-phentermine-weight-loss-schedule/

      Good luck!

  44. Hey guys i just started on 4/20/15 (yesterday ). my beginning weight is 256lbs. My goal, is 156lbs. I really dont know how i feel right now. Dry mouth yes. I have been drinking lots of water. And sucking on peppermints. energy increase idk! I did get a good nights sleep last night so i really dont know if it\’s the pill or the rest. My question is does it take awhile for the pill to kick in? My appetite seems to be the same, im still hungry. I really want this to work. Am i panicking prematurely?

    • Hey Tammy, thanks for your questions.
      For some people the effects can kick in after a couple of hours, while for others it can take a few days. The appetite-suppressing effects of phentermine work differently for different people, so while others have no hunger and have to force themselves to eat, others still feel hungry but find that the level of appetite suppression is enough to help them eat less than they used to. If after a week or two you’re still not experiencing the effects you’d hoped for then perhaps you could speak to your doctor about your dosage or switching to a different brand to see if that helps. For the time being, it sounds like you’re not experiencing the common side effect of insomnia and you feel you have more energy, so this is a positive change which you can use to get more active and feel more motivated.
      Good luck! Sally, phentermine.com

  45. I started taking phentermine 9 days ago and I have lost 10 lbs so far. Only side effect I\’ve experienced is that I can\’t sleep I wake up at 7 am and stay awake till 3 am.
    Oh by the way my starting weight was 239 and I weigh 229.

  46. I was already on the pills last year and lost 30 lb. . Then I keep my weight for almost 18 months then I start gaining back . I gain 10 lb. but for 4 months I lost that 30 lb if you not watching what you eat and drink a lots of water of course exercise then really you will not be back again on you goal . After 2 years I am on the pills again and now I am exercise and if course eating right. but only for I more month

  47. I just stayed Phentermine 2 weeks ago. The first week I lost 14 pounds. The only side effect I have had is the cotton mouth.

  48. I have been on Phentermine 37.5 for 2months and I lost 51lbs my I was weighing in at 251lbs now im 200lbs i love this pill. I tooked it 3years ago and I lost a total of 73lbs. This is a really good pill you just have to make sure you drink plenty of water.

    • What did you do while taking the medication to get these kinds of results??

  49. I\’ve tried diet pills before and nothings worked. I weigh 250 and would like to loose 100 to be at a healthy weight. I\’m worried about throwing money away. This sounds like just what I need just looking for some encouraging words I guess.

  50. Just started phentermine today July 6-2015 and I weigh omg I\’m embarrassed to say this but I weighed in at the dr today at 269 and I\’m only 5ft3 so yes I\’m big and overweight!! I have already noticed I wasn\’t hungry today at all like normal and I was extremely thirsty!! Gonna start drinking more water and get rid of the sodas!!! That\’s one of my weakness and of course sweets are my all time weakness but I noticed today I didn\’t want anything so I\’m
    Pretty excited about all this!!!

    • Congratulations on your start. Hope if works well.

  51. i just started taking phen 37.5, first day i started was 7-18-15.. I weighed myself 7-21-15 and in those 3 days alone i lost 7lbs! I dont have much of an appetite especially mornings i ahev to force myself to eat & when i do i almost instantly want to spit it back out. Only thing thats messing with me right now is the last 2 days ive had tummy pains. I hope it goes away because im super stoked about this pill i have a 1 1/2 yr old and since having her ive gained 50lbs! My dr said aslong as im doing ok on phen she can keep me on it no longer than 6 months.

  52. Hello,
    I started phentermine on July 31, 2015 and so far I have experienced the dry mouth, I kinda find it difficult to eat. I when to my doctor and weigh in 207 lbs and want to lose at least for now 40 lbs. I at times feel a little bit hungry but as soon as I put something in my mouth it feels like I ate a whole elephant. Is it normal? At my doctor\’s office I got B12 shot, and yes I do have a lot of energy in my body it feels like I want to be on the go go go at all times. Normal?
    I hope and pray to get to 170lbs.

    • Hey Meme,
      The side effects you’re experiencing should reduce within the next few days as your body adjusts to the medication. However, it might be a good idea to halve your dosage if it’s possible to split your pill and you will find that you have more of an appetite and don’t feel so wired, but rather just energized.
      Hope that helps!

  53. I started taking phentermine 37.5 on Aug.3 2015, 12 days ago. when i started the pill my weight was 226 today my weight was 219 so i have lost 7 pounds in 12 days. Not so bad. i work out doing cardio at least 4 days a week for 20 mins or so a day and i have also put myself on a 1200 calorie a day diet. I hope to lose 70 pounds and plan on learning a new way of eating and making healthy choices to keep the weight off. I haven’t had any side effects at all with the meds. My energy level is still low but i guess it helped curb my appetite.

  54. I started taking Phentermine Aug 24 2015 weighing in 235 today is Aug 27 2015 I am down to 223 I\’m exercising and watching my diet I have alot to lose I know I can do this

  55. I have been taking Phentermine for 2.5 months and I have lost 30 lbs so far. I am taking it for 4 months total, and I known I will lose 50 lbs total at least. I eat small healthy meals 2-3 times daily (fruits, veggies, protein, very minimal bread/pasta/potatoes), I drink a lot of water, and I haven\’t exercised at all! I am going to start working out though so I can maximize my last 1.5 months on the pill. Side effects I have experienced are dry mouth, constipation, and at first I had muscle twitches at night but that went away after a couple weeks and wasn\’t bothersome. Also, for the first two days I got chills/tingling sensation all over my body at various times… my friend confirmed this is a known side effect, but I didn\’t think anything of it until she mentioned it to me because it wasn\’t bothersome either. This pill is AMAZING and it really works to make you feel NOT HUNGRY AT ALL. I wish I could continue taking it for longer to meet my goal of 70 lbs weight loss total. It is also cheap… $20 monthly, not bad for such FANTASTIC results. I would highly recommend this pill to ANYONE and EVERYONE.

  56. Hi my endocrinologist put me on phetermine 15 I started on Sept 7 2015 and today is Sept 12 I was weighing 194.5 now I’m 187.0 I’m so scared taking this diet pill been having dry mouth been drinking a lot of water and this on going slight headache along with some dizziness it goes away in the evening and I’ve noticed my heart rate slightly going up today heart rate went up to 110 I was so scared I have no desire for food at all just desire for water…my friend says it’s in my head lol cause I’m so scared I’m 46 and I’m just so paranoid I guess I see my doctor on Monday let’s see what he says keep u posted

  57. I have been taking Phentermine since June of 2015 roughly 3.5 months and have lost 46 pounds I drink tons of water probably 1-2 gallons a day. I have completely changed my lifestyle and feel great.

  58. So I’ve actually been on and off phentermine for the past year and a half. I’m on for about 2-3 months and then off for a month, following my doctor’s recommendations. I currently take 37.5mg twice a day. In the 18 months I’ve lost over 90 lbs. It came off quick at first and has slowed down a lot, but I continue to lose about 0.5 – 1 lb per week.

  59. I have just started taking phentermine. I hope to lose 25 pounds. This will really help my self-confidence. Hopefully, I will be able to keep the weight off.

  60. So, I start taking Phentermine 35 mg on Friday October 30, 2015, two days from today. I am very excited about this weight loss journey. I am confident I will be able to completely change my eating habits and finally stop being lazy about exercising. I currently weigh 284 lbs (my heaviest). I would like to lose 100 lbs within 6 months. My goal weight is 200 lbs but if i can certainly make it to 184 lbs that would be MARVELOUS! I am not sure if this is a bit much to lose in such a short amount of time but this is definitely a goal of mine. I have read so many reviews on Phe. I was discourage by many reviews but everyone’s body reacts differently so I decided to give it a try. I am going to take a picture of myself naked this Friday and every two weeks after take another picture to compare my weight loss. I am nervous and excited at the same damn time 🙂 WISH ME ALL THE BEST 🙂

    • Hi Jaz,
      Taking a photo is a good idea as then you’ll see the changes to your body and not just on the scale, which can be a very unreliable guide of how your body is improving due to the work you’re doing. Your six month goal of 84-100 lbs is a little optimistic – it’s great to have a goal to aim for, but just be aware that this is a lot more than the average person would lose in this time, so you should feel happy to make progress, and around half this amount would still be a really great achievement in 6 months.

  64. I started 37.5 Phentermine w/10 mg Prozac on 1-12-16. I’m 5’8, 250lbs. I weighed myself today, 1-15-16, I lost 9lbs in 3 days. I can’t believe it. I haven’t even had a chance to excercise! I have no appetite at all. I have to force myself to eat and my energy level is through the roof. I drink plenty of water throughout the day. Now, I have experienced side effects..dry mouth, slight headache if I don’t eat and my eyes seem to be very sensitive and a bit watery..will talk to doc about that. I know I dropped water weight but I also dropped one size! This pill is allowing me to change my lifestyle while losing weight. Good Luck.

    • Great news Kimmy, well done! Let’s hope the side effects reduce soon for you!

  65. Just started taking phentermine 30 mg capsules – it’s been 4 days, I exercise 30-45 minutes a day, drink up to 10 glasses of water, I eat 3 meals mostly eggs with ham in the morning crab meat or salad with ranch and some broccoli for lunch and then whatever is for dinner I have cut out soda even though I only drink diet I haven’t had any sweets since I started I make sure I hit 1200 calories a day because I don’t want my body to go in starvation mode and I want this to be long term but I haven’t lost any weight at all what else can I do?

    • Hi Cristal,
      If you feel that phentermine is helping you to be more active and to eat better then it’s working as it should, then it’s up to you to lose the weight. It’s good that you’ve cut out soda (diet is JUST as bad as regular though, so try to keep away from both) and sweets, and the water will help you to lose. However, your diet doesn’t sound like you’re eating the best things; ham is processed and usually high in salt, so it’s best to skip that unless it’s really good quality and lean. Eggs in the morning are great, but they are better combined with a source of fiber and carbs, such as whole grain toast. A salad with some lean meat for lunch is good, and then a healthy dinner with plenty of vegetables would be perfect. Snacking on healthy foods like nuts, yogurt and fruit is also recommended to keep your metabolism ticking along, so as not to go into starvation mode as you said. Good luck!

  66. Hello! I’ve never had a problem with weight until 5 years ago.. Was an avid power walker, was in the best shape of my life and weighed a healthy 115 lbs. Then it was like a switch flipped inside my body. Now I’m 175lbs with a waist size of 42.5 inches! Im 5ft.2in. and 50 years old. I cry if I accidentally see myself in the bathroom mirror when getting in or out of shower. I got a YEAST Infection along my belly roll it was the most humiliating thing to smell the horrible odor coming from me. I’ve stopped sleeping with my husband because I’m so embarrassed of myself and we haven’t been intimate for 3 years. I broke down and went to a weight loss clinic yesterday and was prescribed Phentermine 37.5. Its my first day. . He is also giving me weekly injections of B-12/ Lipo/and Chromium. He has also given me those same vitamins to take daily along with Cinnamon Capsules to take with my prescription. He has written me a great diet to stick to that’s so easy! I FEEL AMAZING TODAY! I’ve drank water out the wazoo, no side effects and crazy energy! My spirits are amazingly high. I hope this euphoria never ends.. I actually feel like walking again!!!! I AM going to be the beautiful woman I used to be. I WILL BEAT THIS FAT!!! Thanks for letting me vent!

    • Thanks for sharing Linda, we wish you the best of luck!!
      Sally, phentermine.com

    • your story is so similar to mine – I’m 5 feet tall, 49, and do NOT like my view of the mirror!

      I wonder – what is the purpose of the cinnamon capsule?

      remember this: You have ALWAYS been and still are that beautiful woman! It’s just that some fat has made a coat around you and it’s harder for you to see her right now. Watch out world —
      Here she comes 🙂

  67. Hi there! I have struggled with my weight all my life. (I am only 31 but it has always been a struggle) A few years ago I took Phen and dropped down to under 200 pounds and it was wonderful. This time around I am a mother of two children and want to lose the baby weight I have put on. I started taking phen 2 weeks ago today. I started out at 221 and I am now 211. The first week I lost about a pound a day and was super excited. I have been stuck at 211 for a few days now and I am trying to figure out what I should do. I have a hard time eating enough and I have been doing atleast 30 minutes of some activity outside of the normal running after my kids every other day. I have gone down a dress size which I am super excited about. I hope to lose another 15 pounds. It would be so nice to be back under 200 pounds again. I want to lose more than that eventually but small goals in the beginning. 😀 I will check back later and update.

    • Hi Desiree,
      Well done! You’ve lost 10 lbs in two weeks which is a really fast rate, so it’s natural that your body would need to take a few days to readjust. Just continue to do what you’re doing, don’t obsess over the scale (weighing once a week is enough) and be sure to appreciate other goals you’re reaching, such as dropping that dress size, having more energy, getting stronger/fitter etc – you’ll start to see a drop in the scale very soon!

  68. Hi all! I just wanted to share my journey on phentermine,
    So I started it on 04/01/2015 my start weight was 215 but my highest weight was 230 and that scared the crap out of me as I was only 18 at the time, I started when when I was 20 obviously, anyway, at first I was very skeptical as I had tried almost every diet fad out! This time I was determined to put in the work required to get the results I wanted , I took my before picture, and the first month I simply ate different, and that alone I went from 215 to 192! That’s 23 pounds! I was overwhelmed! And so happy! So I signed up for a gym and started working out 5 days a weeks for an hour, mainly doing cardio, my ending result was 155! 60 pounds lost in 4 months! I stopped taking phentermine as I didn’t want to be reliant on it and wanted to continue on my own, I did just fine in maintaining my weight, but unfortunately some bad luck came my way causing me to not have a job and no more gym, I let things get out of hand a little causing me to put on about 20 pounds, I feel the effects of it and absolutely hate it, so I am back on phentermine again, and hoping to regain control of my weight and hopefully lose that 29 pounds and a few extra pounds to as I want to wear the two piece bathing suit I bought for summer! Good luck everyone! Just remember to stay focused and don’t let anyone bring you down! Know that you can say no and that there’s a cheat day for a reason! I believe that anyone who’s puts the work in to achieve their weight loss goals will succeed!

    • Good luck Julia, you can do this!!
      Sally 🙂

  69. I just started Monday on phentermine I am 48 and weight 217 and 5’8″. I am not happy with my body. I look at myself in pictures and can not believe how big I look. my goal is 150. I know I can do this. it is now Thursday and I am down to 215. I now a lot of this is water weight. Next week I will start walking about 2 miles a day 5x a week. I hope this helps. Cheers to me 🙂

  70. Hi. I’m 30 year old female and started Phentermine 37.5 on January 30,2015. I started at 196 and in less then two weeks I lost 11 pounds. It’s been a week now and I’ve lost nothing, it has me worried that I am stuck again. I eat healthy and drink water and work out 6 days a week. Plus my job is demanding. I don’t know what I’m doing wrong or if it’s suppose to really slow down. Do I drink more water? I gave up starches. Sweets, candy, juice – all of it. As a woman I’m trying to keep it light weight at the lifting no more then 45 pounds. I’m feeling defeated again.

    • Hi Dawn,
      Really you shouldn’t worry – you lost 11lbs in two weeks, which is great but it’s also a BIG change for your body. Often weight loss doesn’t go in a steady downward slope, there are stops and starts all the time, and normally it´s because your body is adjusting to your new weight, your new regime etc, so when it’s ready it will go back to dropping pounds but you just have to give it some time and continue doing all the good things you’re doing. Phentermine is meant to give you the help to work out and cut back on unhealthy foods, so if you’re able to keep up the good habits then it’s working, and the results will come as your reward. Well done and keep strong!
      Sally, phentermine.com

    • Recent research shows no reason women should keep lifting light. Hope you were able to get back on track.

  71. I’m a 54 yr old female with type two diabetes 5ft8 and 225 lbs. I lost 25 lbs over a year ago by cutting out some carbs. Stuck at this weight. Don’t excercise because my knees hurt. Started phentermine two days ago and although feeling a bit jittery I feel much more energetic and my knees weren’t hurting as much. Will keep my progress posted. Fingers crossed. How does one lose the extra skin after weight loss without major surgery? Exercise alone surely can’t help?

    • Hi MommaJ,
      Thanks for sharing with us – it sounds like the phentermine is working for you already! Some good ways to get active without putting pressure on your knees are to go swimming or try pilates, then, as you lose weight the pain should decrease.

  72. Anyone off phentermine and able to keep the weight off? I really worry about gaining it all back once I stop taking it.

  73. Hey!
    I’m Jo! Well, I’ve been reading all the comments and what all have been saying in re: to phentermine. And granted, I see everyone’s different stories, reactions…I’m really looking forward to starting this journey. I was wanting to get the gastric sleeve surgery. As much as I wanted it, I guess the Good Lord didn’t feel it was best for me, lol. I’ve no insurance, well…no, I do have insurance. It’s thru a local hospital. The doctor that performs the surgery is a part of the same hospital. But, he wants the $ out of pocket. I just don’t have it like that. I will tell you…I was tearful. I have carried 5 babies & am close to 300. I am DISGUSTED w/myself! This is THE BIGGEST I’ve EVER been. So, w/the 5 pregnancies & carrying the extra weight..I now have arthritis in my pelvis. If I walk more than 30 min. the pain I feel in my pelvic area later in the day, puts me in tears & I cannot walk. Taking just one step hurts so bad. Feels like I’m dropping a baby. I’ve been checked out by my GYN & all my parts are still in the right place, lol.
    After an MRI, I was told that due to multiple pregnancies & weight, I’ve arthritis in my pelvis.
    B/c of this, my independence has gotten limited. My husband works & by God’s good grace, we’ve survived. But, I’m 5’2 & soon to be 47. I’ve gained a great deal of my weight after moving. Now, since I wasn’t able to get the surgery, my doctor mentioned putting me on phentermine. I know someone whose been on it since October & she’s lost 50 pounds. I also recently bought myself a bike! I loved riding as a kid/teenager in the 80s & it kept weight off me! My hubby and I are taking a spin over the weekend and I’m excited!
    As for Phentermine, I’m going into this with a positive attitude. I’m a tad nervous about side effects. And if someone could pls help me understand what type of diet…
    Can you take phentermine longer than 3 months? I’m only asking b/c I do know someone who has been taking it since Oct. 2015.
    You’ve all been so inspiring, thank you! I’m open to any advice/suggestions….& I thank you in advance 🙂

  74. I have been taking phentermine for 7 days now I have lost 15lbs
    I drink about a gallon of water a day and I can only eat 1000 calories a day and that’s making myself eat. And walking for an hour every day.

  75. I started with headaches for the firsts four days three days and now on the 8th day I have a headache but now I feel like its not working its not doing much for my appetite but I have been trying to manage what I eat

  76. I just started taking this medication yesterday. I’m taking it to counteract a medication that causes weight gain. I’m having trouble sleeping at night. I do enjoy the energy it gives me and for the first time since my illness I want to be active.
    I have chronic abdominal pain and an issue with malabsorption. I have one healthy meal a day and the rest of my day I drink vitamin rich shakes.Any advice on assisting with sleeping? I take this medication early in the morning so not sure why I can’t sleep.

    • Hi Patti,
      Insomnia is a common side effect of phentermine, and something which the majority of users suffer from at some point. Many people find it helpful to halve their dosage in the first few days while they get used to the side effects. For more information on why insomnia happens and other ways to reduce the problem, take a look at this article: https://www.phentermine.com/blog/insomnia-from-phentermine/

  77. Hi I’m 29 and I started taking phen on Feb 2 2016 I weighed in at 311 after taking it I lost 26lbs my first month not really doing any exercise because my job is hard enough but I’m going to start soon.. I snack on healthy foods through out the day and at least once every other week I enjoy a cheat meal.. I’m doing great and feel motivated to reach my goal weight of 180.. Everybody keep it up and don’t lose hope…

  78. I just started taking phentermine today 3/27/2016. My current weight is 213 lbs. I am hoping to drop about 70 to 75 lbs. over the next few months. I hope this will work for me. From what I have read so far, pretty much everyone is successful with this.

    • I started that day too! Curious how it is going for you?

  79. I am 58 5’6 and disabled with 4 hip surgeries. I have lost 50lbs on my own in the last year. 4/14/16 I weigh 213lbs. Have high blood pressure and moderate sleep apnea with 27 episodes an hour so loosing weight is crucial to me for health. Dr prescribed this drug. I took it on 4/15/16 friday its now 4/17/16. And I weigh 206lbs in 3 days .. a 7lb loss. Wow !! Excited

  80. I’m 184 I wanna be 160 or 150 in a month

  81. I just began today…
    Start weight 176
    Goal weight 123
    Doctors orders: 1/2 pill for the first few days, then the full 37.5 strength. 1200 calories per day and either one hour of walking or 45 mins on the elliptical or walk/jogs five days each week. My doc figures I’ll lose ten pounds a month over the next three months before I discontinue using it. I plan on following orders strictly so praying she is right! That is just over half the weight I want to lose, that would be huge motivation!

  82. I started with half pill on Friday 10 June 2016 weighed in at gym at 210. Half a pill Saturday and whole pill Sunday. Monday half pill and Tuesday whole pill. Today is Wednesday 15 June half pill weighed in at 202 today unbelievable

  83. Hi everyone! Been seeing a weight loss doc since Jan 2016, Started out at 226 my cholesterol was 700 borderline type 2 diabetic and my brother went blind within a year and died within 3 years of being diagnosed. I knew the day was coming for me since everyone else in my family is also diagnosed a diabetic. For me it happened after a back injury and 4 years of recovery then 3 years fighting planters fascitis. After 8+ years of fighting injuries I went from 152 to 226. So my journey began. He put me on a slew of supplements and diethylpropion. Started with proteins and education. Changed my food intake. Lost 24lbs. I have managed to loose 8 more lbs after flip flops in the weight. I am finally able to walk in short spans of less than a mile then rest my feet. I ride my bike and walk steps. The diethypropion I feel has not really done anything. So I weighed in today and put on a pound this devastated me. So I asked to be put on phentermine. I cut the pills in half after reading here and will do half for the first week. Will try to check back after with updates. I wanted to quit today by the way. I pay cash to see the doctor. I felt I was not getting any results I could not obtain myself. Is that the wrong way of looking at it?

  84. I’ve been watching what I eat for three days and taking half a pill for the last two. I’ve lost 5 lbs in that amount of time – 3 days! I know it’s all water weight, but still! I feel great! I have a ton of energy, no trouble sleeping, no jitters, NO APPETITE, and the only symptom I have is dry mouth. I don’t even mind the dry mouth because it reminds me to drink, drink, drink that water. I’m thrilled!

    • Hi Corey,
      Thanks for your feedback, it’s great to hear you’re doing so well and with no side effects apart from dry mouth! We’d really appreciate it if you could leave a review for us here: https://www.phentermine.com/reviews.htm so that we can share your experience of phentermine with even more people. You can just copy and paste what you’ve written above. Thank you!

  85. I will like to loose weight

  86. Started taking phentermine about a week ago. Took a few days to adjust. Have much less appetite, although at meal times am still hungry if I haven’t eaten much. Trying to eat small, healthy portions many times throughout the day. So far I’ve lost a couple pounds, but it fluctuates almost daily, and at times that discourages me because I might be heavier one day than previous.

    I have more energy, am happier, more focused. The first few days I did have some trouble sleeping, but have adjusted pretty well now. I do have dry mouth like others have, but I also think this is a good reminder to stay hydrated, which is good for you!

    My doc only prescribed for 30 days and told me I have to lose at least 10 lbs or she won’t refill the Rx. I’m a little nervous because I have had NO luck with losing weight the past few years. I really, really hope this is the key to helping me get going in the right direction! Diet alone won’t result in me losing weight, so now that I have adjusted to just starting phentermine, the next step is to incorporate good work outs as well.

  87. Started taking phen 30.mg 8/1/2016. Lost 7 lbs first week (water weight obviously). Lost 2 lbs the next week, 6 lbs (3rd week) and so far 2 lbs (4th week i have 5 more days to go). So I think i will lose total of 20 lbs this month. But I had to cut pill in half because it gave me bad insomnia as well as rapid heart rate.
    So after 3 days of insomnia (and no appetite at all) i cut pill in half. I eat usually cheerios and almond or 2% organic milk for breakfast than around 11 am i take my pill. I drink lots of water (galon per day), after that i do not feel hungry at all. My lunch is usually peace of meat and salad and i snack on almonds or apples. I dis eat spaghetti and rice also ( but all my portions are 1 cup on that) as well as some bread (2 slices of wheat mountain bread). So i eat usually meat, veggies and fruit, however in the last 3 weeks i did not eat any sweets at all. No chocolate, no icecream nothing. I take carbs from fruit and vegetables. I think what helped me lose so much weight is the fact that i do not eat over 1400 calories and i am counting my calories so that works for me because my doc told me you can diet and lose weight but you will gain it all back if you are on very strict diet so i try to eat healthy. Sometimes im not hungry so i just take protein shakes to help maintain 1400, because if you eat less than that your body would go to starvation mode and you will stop losing weight despite taking phen.
    I also take flaxseed 2 spoons per day and i run for about 35 minutes per day (just to mention when i started i could harsly walk).
    My initial weight on jun 1 was 265 lbs, by 8/1 without phen i got to 246.5 lbs and now i am 229 lbs. i hope to be 226 lbs in 3 days.
    To conclude 30 minutes cardio 5 to 7 days a week, half of the pill, 1 gallon of water per day, no sweets and everything else in small portions works for me. Hope this helps. My goal weight is 178 as i am 6 ft tall.

  88. I’m 37 years old and 5ft, I started with a weight of 180. I’ve always been petite, but after kids sh*t hit the fence. After my last kid 3 years ago I was tired of not being able to lose the weight. When my son turned 2 that’s when I said enough is enough. I lost 25lbs on my own eating well and going to the gym but plateaued. So I finally went to the clinic and they prescribed my phentermine, today is the first day and I have no appetite, but forcing myself to eat small portions. I’m very excited for what’s to come. Good luck everyone!!!

  89. I’m 45, and I’m praying phentermine helps me in achieving my lifestyle goals. I suffer with PCOS, so losing weight has been impossible. Add a couple of serious car accidents then extensive back surgeries, which left me with faucet joint arthritis throughout my lower back. 2 years ago I could only walk 1/4 mile. Steps killed me. My weight was 240. I worked out and got a trainer and was able to get down to 212. Then the weight crawled back on. June 20, 2016 I was 233 at the doctors office. I started walking daily with friends. We built up to 8 miles a night and a very lean diet with vegetables and lean proteins. I’ve been stuck at 209 for over a month. Very frustrating to walk 48 miles extra a week and not see results. I had to prove to my doctor I was determined before he would prescribe me the phentermine. I started taking the phentermine on 10-5-16. I’m down to 204 already. Let’s see how far I can go with this……success is the only option…..

    Starting 209 with my BMI in the obese category
    Current weight 204
    First goal 185….that brings my BMI to overweight
    Final goal 154…that gives me a normal BMI

  90. Hi. About 4 years ago I took phentermine for 5 months and I lost 60 pounds. The only thing I did was work 8 hours a day and I drank a lot of water. I did change my eating habits as well which was easy because of my appetite. Unfortunately when I stopped taking it I gained all the weight back because I started pigging out on fast food and sweets. I thought since I was slimmer that I would stay that way. Well I thought that I would try it out again so I’ve currently been taking it for 3 weeks now and have lost 7 pounds. For the past week I’ve been working out on Wii fit for an hour a day. I drink 8 bottles of water a day and have cut out fast food. I think I will keep it off this time. Good luck everyone

  91. My doctor prescribed me phentermine on February 2, 2016. I weighed 216 lbs. She also put me on a 1200 cal. diet. I stuck with the diet and taking the pills (0.5 in the morning and 0.5 at noon). As of today, November 30, 2016 I weigh 166.4 lbs. I have lost 50.5 lbs in 9 months. I am still 27 lbs away from my goal weight which is 140, but I am extremely proud of how far I came. Hopefully in a few months I will see my goal.

    • Hi Kaylie,
      Well done on your weight loss and good luck for the rest of your goal!
      Sally, phentermine.com

  92. I started Phentermine in September. I found out that I had high Cholesterol in June and decided that I would try and lower it on my own (I was warned the cholesterol medicine is very damaging to muscles). I lost 10 pounds just changing diet a little. I had already eaten fairly healthy (at least for portion and some not so healthy snacks more than I should was the problem) so it wasn’t too hard to change. After the 10 pounds I was able to maintain it but not lose anymore. So in August my Dr offered Phentermine describing the side effects what to watch for and that no matter what by May 2017 I would need to go off it and explained that it is an addicting drug. I was skeptical about it because of addiction. I do not have addiction problems myself but it runs in my family for various drugs and alcohol. I talked to trusting friends family, church members and my husband and let everyone know I was going on it so they can all help to watch for signs of addiction.
    On September 5th I started Phentermine and Vitamin B-12 I weighed 262# when I started it It is now December 8th and I weighed this morning at 226#. I have lost a good amount of weight considering I haven’t started working out I do walk a bit. But am starting a workout routine this week to speed things up. I want to be off the phentermine sooner than May. My goal when I started my weight loss a year ago was 220# I am very close to getting there. My goal on the phentermine is 200# the appointment after reaching under 200# I will discuss with my Dr a lower dose to start moving off it.

    I did start at the 15MG and went to the higher dose the next month. When I went to the higher dose I was worried it would be too much energy so I took half before breakfast and half after lunch. (this is not as prescribed I did tell my Dr it was planned though because my sensitivity to caffeine in the past he said it was ok for me) I now take the whole pill first thing in the morning and have no problems. and my B-12 (5000 MG dissolving) around 2 or 3 when I start feeling a little tired. On the 15 MG if I took it in the morning I was tired by 2pm and took a nap at that time for about 2 hours. I use to never take naps. So I had to change times on taking it. I do not have that problem with the 37.5 MG.
    I do find myself not eating and have to make myself eat. It is very bad to not eat if you starve your body of food it will hold onto what you give it longer posing a chance at not successfully losing weight. The phentermine definitely makes me not hungry I normally don’t eat breakfast since everything I used to eat is high cholesterol lol (eggs OMG tons!!!). I snack healthy so I don’t go too long without food, you will notice if you do your stomach will start to growl you wont feel too good headaches could start. I just don’t recommend not eating and using the pill as an excuse not to its too dangerous.
    I worry about the weight coming back. But I also know that I make healthier choices now I rarely eat out and if I do I order small and can’t finish it anyways. I tend to get salads if I have to eat out anyways. The weigh loss won’t be as great if you don’t do anything to help it. There is no miracle pill to just make it go away it does take effort still.

  93. I am 42 yrs old 215 lbs and started phentermine 1/26/17. I quit smoking 2.5yrs ago and despite diet and exercise have continued to gain wt. I was always of normal weight prior to. This has been utterly devastating and has obviously caused a massive body image disturbance. I do not drink alcohol and i started back to riding my stationary bike 45 min 5 days a week. Any advice on how to get the best result with use of phentermine is welcome!

  94. I started taking Phentermine on 1/5/2017. I am 51 years old and my starting weight was 205lbs. I just had my 1 month weigh in and I lost 17.3lbs my first month!! My goal when I started taking it was to lose 30lbs and then take it 10lbs at a time.

  95. Hi Everyone,

    I started the phentermine program (37.5 MG) 30 days ago and just had my first follow-up visit yesterday. 29 days on phentermine and my weight has dropped from 231 lbs to 203 lbs already!! So for losing 28 lbs in 29 days, I am super impressed with this program. I even skipped the pill about three days of the 29 to give my CNS a break (it speeds you up). The pill has changed my eating habits dramatically. I was probably eating well over 5000 calories a day before I started. This would usually be from a drive through window. The pill completely kills my appetite and I immediately dropped to about 1000 calories or less per day. Typically I only eat once per day in the evening (only time I feel like I am able to eat). I have not done any exercising yet and I sometimes feel cold (especially in the feet) from the body using reserves. I also seem to have a new found sense of disgust for fast food, carbs and processed foods. All I eat now is chicken or beef with no cal seasonings (usually grilled or broiled), mostly green veggies and fruits for natural carbs and energy. I take a multivitamin and 1000MG of B12 daily along with the phentermine in the morning. I mostly drink coffee with no cal sweetener and half/half or juice during the day. I hope everyone gets positive results!! Good Luck!!

  96. Hi, I just my weight loss journey. Yesterday I weighed in at 223 & my goal weight from my doctor to have a healthy bum is 160. I\’m very excited & cant for my results.

  97. HI I\’m Eileen S I lost 89 pounds and I am so thankful for the jump start that I got with this prescription of phentermine from my doctor. It helped me with control and gave me the energy I needed to get out there and go for long walks, hiking in the mountains and even my favorite roller skating again!!! I was skeptical about this and to be honest I thought I was throwing money away but I invested in me and the returns are amazing.

    • Congratulations Eileen! It sounds like phentermine worked great for you. If you’re interested in sharing your story with other phentermine users, we’d love to hear more about your journey on our Success Stories page here: https://www.phentermine.com/phentermine_success_stories_form.htm.

  98. Hello, this is my 2nd month taking phentermine. The 1st month I lost 16lbs. So exciting to see the scale go down but it seems like no one notice. What a bummer lol. I started 6-5-17 @256 so a month passed and now I\’m at 240. I\’m around 5\’5. I walk on treadmill in the morning for 1 hour . I eat dinner before 6pm. And around 7:30ish I go walking on the track for 1hr. So that\’s 2 hrs a day and 5-6 days. My eating habits changed, I no longer eat fast food, nor drink sodas etc. Somedays I do have cheat days not consider cheat days I eat regular food but just a smaller portion. The thing that scares me is when I get off the Phentmerine. Will I gain my weight back ? Will I still be exercising. I\’m not sure if I want to get on it next month. I really want to try and do it on my own. But overall I am very happy how things going right now. I would be very very happy if I get to 199.9 lbs..lol

    • Hi I take phertermine and losted 12 lbs in 12 days…my friend takes it and she losted about 80lbs. she stop taking it and she gained maybe 8 to 10lbs in 3 months and she now takes phertermine one time a week and she exercise all a lot like you do. She don\’t gain but loses about 1 pound a month. She talked to her doctor and he said it was fine that she takes 4 pills in one month because it wont her her. I hope take this helps you

  99. I started to take phentermine on July5th and weighed 244lbs and now on july17th I weigh 232lbs. I excersie maybe 20mins 3 or 4 days a week ..50 sit ups,50 squats, 20 step ups on each leg and lifted 15lbs pounds and now 20 lbs. I don\’t feel hungry but I eat a little through out the day and drink lots of water. I don\’t take the pills everyday because I stay awake at night but I never skip more then 2 days without taking it.

  100. I\’m 36 and at the start I weighed in at 276lbs. I am diabetic and never really did anything to control my diabetes. I tried taking metphormin but I had pretty much every negative side effect you can have with them. I started phentermine and said goodbye to carbs and anything with sugar in it. I ate 2 meals everyday. Small portions of meat and vegetables. It\’s been 4 weeks and I have lost 40 pounds. I had a cheat day every Sunday where I would eat whatever I wanted including sugar. It\’s only been a month and feel like the phentermine doesn\’t effect me at all anymore, what I mean is I\’ve stopped taking it and I\’m still not hungry all the time. Guess I\’ll sign up for another month, want to reach my goal of 193. Then I\’ll eat till I gain about 20 pounds and then I pick up excercising again.

  101. I am 34 and I have been on the phentermine for two weeks and I lost 2lbs I don\’t have a appetite much but I started walking every day. I am on 30mg I feel like I ain\’t loosing that much.

    • Hi Debra!

      We recommend contacting your prescribing doctor if you really feel that phentermine is not working out for you. There could be underlying causes for this, and your doctor could help you discover if maybe another approach is more effective. However, also realize that all bodies react differently, and age, metabolism and lifestyle are very important in the effects they have upon weight loss. A good, healthy weight loss number is about 2 pounds per week. Although you can lose more than that, there is a risk for those that lose too much weight too fast.



  102. I personally used Phentermine prescribed by my PCP in the past. It truly helped curb my appetite immediately. I then made a food journal and didn’t go above 1500-1800 calories daily while choosing a wide variety of foods. I only played the game Just Dance at home at least 5x weekly for 30+ minutes and three in some normal sit-ups, push-ups, etc for 10 minutes before dancing (obviously stretched beforehand). I drank water like a mad woman. I lost over 70 pounds in a 5 month time frame, remember it is only prescribed 12 weeks. I did full doses on rare occasion and took half doses a lot so it lasted longer than it’s 12 week span. However what no one warns you that sometimes you shouldn’t dive head first into a completely new lifestyle change!! I had almost completely cut off fatty foods to get the most out of this in the short period they would allow me to use Phentermine. I allowed myself one cheat day per week to go to 2000 calories with any food of choice. I stopped using the medicine for month or so and I started having TERRIBLE stomach problems. Anytime I ate anything with a slight amount of fat I had these almost like heart attack episodes. I decided I would go to the ER during my fourth attack. Come to find out, I completely threw my body into whack by my drastic lifestyle change. I was found to have a gallstone blocking my ducts causing liver failed and pancreatitis. I was hospitalized for a week and ended up having my gallbladder removed. After all my hard work, dedication, new found love for exercise and eating healthy I had to take time off from it to recoup. I may have went head first and shocked my body but it certainly made me feel great losing 70 pounds and loving exercise. At the time I was breathing better, losing weight, boosting self esteem, finally enjoying exercise which helped with mood, and thought I was eating right. Moral of my story is I went to hard to get results and hurt myself in the end. A year later I gained back half of the weight lost and felt worse because I worked so hard and it hurt me in more ways than one. I strongly suggest this medication to the determined individual with REALISTIC AND HEALTHY lifestyle changes…only at a slow pace! It works wonders but will definitely hurt you if you do not have realistic goals. Even if your physician wants to achieve its max potential in 12 weeks, only do what you can in a healthy manner! I was so thrilled that I continued my eating healthy and exercising after the med..but then would be upset because I couldn’t lose much at all without it and still had a target I just didn’t meet (even after 70 pounds). In the end it really hurt me physically and emotionally and I only would recommend this to those who can control themselves in a manner of knowing and keeping healthy boundaries no matter what more you could lose. Otherwise be ready to gain most back and potentially harm yourself physically and or mentally just to achieve a number you will not keep. POSITIVE REALISTIC BOUNDARIES folks!! Otherwise do not even attempt this medication.
