Read their stories and then browse through the dozens of inspiring success stories at the end of this page to explore other users' motivations, routines and diets!
Expected phentermine weight loss is 5% of starting body weight in three months .
This means that your healthcare team will expect you to lose at least 10 pounds if your starting weight is 200 pounds, or at least 15 pounds if you start at 300 pounds. The average weight loss on phentermine is anywhere from 3-5 pounds per month [2-4].
That being said, many patients see phentermine results that far exceed these minimum goals. The video below exemplifies just some of the wide variety of phentermine weight loss results that real users experience.

Phentermine is designed as a "short term adjunct therapy" to complement healthy lifestyle changes and help patients manage obesity . When it comes to prescription weight loss drugs, "short term" is generally interpreted to mean no more than 12 weeks at a time .
So, when prescribed as directed, phentermine weight loss pills are taken for 1-3 months.

“It’s all about the small victories. Buying new clothes has been amazing… Getting amazing compliments from everyone has been so rewarding.”
Monica was disheartened by what she saw in the mirror, so she decided to try phentermine. Along the way, she suffered from dry mouth and had trouble giving-up sweets, but she loves her phentermine weight loss results.
With healthy eating, regular workouts and a boost from this medication, Monica has lost 50 pounds in just three months (check out those amazing phentermine before and after pics!).
When asked what advice she would give to other people interested in losing weight with phentermine, she said: “Exercise is very important, don’t give up, and don’t let no one bring you down."

“I get stopped in the hallway at work and people tell me how awesome I look. Men check me out!!!”
Sarah was always a “big girl” growing up. As she got older, she kept eating like she was sixteen and the pounds piled on little by little.
At her heaviest, Sarah weighed 239 pounds. She was embarrassed to be tagged in pictures on social media or go out with men. That’s when she decided to talk to her doctor about phentermine.
In just three months, she lost almost forty pounds! To achieve these impressive phentermine results, Sarah worked closely with her doctor to set realistic goals (around 10 lbs per month) and watched her portions while following a low-sodium diet.
For exercise, she goes to the gym with a friend and chases toddlers around all day at work. Sarah says the biggest sacrifice on her path to phentermine before and after success has been partying less, but the compliments and the feeling of too big jeans falling off her now-smaller hips makes it all worth it.
A 4-6 month prescription of phentermine is only slightly more than the recommended prescribing period. This treatment duration also encompasses patients who take two rounds of medication to achieve more significant phentermine results.

“Always stay focused on your goals. Don’t get discouraged if you don’t get the results you were hoping for right away... It’s really great to wake up in the morning and not feel any pain in my hips or my joints.”
Sabrina decided to lose weight with phentermine when her doctor presented her with two options: monthly shots for pain management or weight loss. As a professional woman in her mid-40s, spending the rest of her life in pain was not an option.
It was a little hard to workout at first, but Sabrina could not be happier with her phentermine weight loss results. She has completely made-over the way she eats and loves that she does not have to shop in the plus-size section anymore. Plus, best of all, her joint pain disappeared!
Starting Weight: 367 lbs
Current Weight: 277 lbs
Total Weight Loss: 90 lbs
“Just keep at it. Don't get discouraged... It's normal to have good days and bad days.”
Brent had always been overweight, but things only got worse as he aged. Despite his consistently-good bloodwork, he eventually weighed-in at 367 pounds and realized he never wanted to see 400 on that scale.
When Brent asked his doctor for help, his doctor prescribed phentermine. After almost 6 months of meal tracking, consistent exercise and phentermine, Brent has lost 90 pounds!

“I’ve lost 35 pounds with phentermine so far... I just go at my own pace. When I set a [time-specific] goal I get extremely disappointed if I fail and I tend to give up. So, I just remind myself to keep pushing and that I can do it on my own time limit.”
Melissa knew she needed to make a change when her doctor prescribed cholesterol medication, in addition to her already-routine blood pressure medication.
At first, she struggled to give-up soda and energy drinks, but now Melissa avoids energy drinks all together and only drinks 1-2 sodas per week. Her stunning phentermine weight loss results have enabled her to run and play with her 5-year-old daughter, while also decreasing her need for daily blood pressure medication.
For others hoping to achieve similar phentermine before and after success, Melissa offers some great advice
“Start slowly. Most people make multiple huge changes all at once and they end up failing. Make 1-2 small changes at a time. [For example], increase your water intake and cut portion sizes. Do this for a month or two then add 1-2 more changes. In my experience, when I change everything all at once I give up extremely quickly. Since trying things with a different approach I have had great results.”
Patients who take phentermine for 7-12 months may either use this medication continuously, or take multiple rounds of phentermine punctuated by short breaks (as directed by their doctors). Only a medical doctor is qualified to assess if the potential benefits of extended phentermine use outweigh the potential downsides.

Since starting phentermine, she has lost almost 50 pounds by cooking more, eating fewer processed foods and staying active. Stevie warns about the side effects (like dry mouth and constipation), and encourages everyone to do their research before taking these pills, but definitely loves her phentermine weight loss results overall.

Now, after accomplishing these amazing phentermine results, Mayling loves wearing smaller clothes, having better self-control and taking advantage of her increased stamina & energy.

Her biggest struggle in achieving these phentermine results was eating healthy while her husband snacked on junk food, but she loves the newfound energy to keep up with her kids!
For all the people out there who aim to achieve similar phentermine before and after success, she says: “Things can get better if you want it bad enough!!”.

“I have always been overweight and I was always frustrated that it was so hard to lose weight. I tried every diet I could Google from low carb, to low fat, to only carbs.”
Chrissy wanted to lose weight before her wedding. She didn’t want to “feel fat” on her big day so, with nine months to go, she asked her doctor about phentermine.
When she started treatment, Chrissy noticed that she couldn't finish big meals anymore and felt guilty about cheat days, which made weight loss easier. After months of hard work, she loves her phentermine before and after photos and felt absolutely beautiful on her wedding day!
Plus, after losing over 50 pounds, Chrissy has the energy and freedom to take part in activities that she would have definitely avoided before (like zip lining!).

“I decided if I was going to finally make a change I would do it right this time – so I ate healthy, began a 30 minute a day, 5 days a week gym routine and the weight started to fly off.”
Michel was overweight his entire life, topping 200 lbs in high school and over 300 lbs in college. Despite his fun and outgoing nature, his weight held him back from lots of activities.
When he realized everything he was missing, he decided it was time to slim down. After trying multiple celebrity-endorsed, over-the-counter diet pills with no success, Michel heard about phentermine.
For Michel, the hardest part of getting healthy was learning self-control in social situations. After losing almost 140 pounds, however, he loves watching people’s reactions when they see him after a long time and don’t even recognize him because he is so much skinnier.
For him, the biggest sign that he'd finally gotten his phentermine weight loss results was when a salesperson told him he was so thin that he needed a slim-cut suit!
