Phentermine is prescribed as a short-term treatment for obesity, so we tend to wonder a lot about life after phentermine… How will it look? Will I be able to keep the weight off? Do I need to eat like this forever? What challenges should I expect? There’s a common misconception that it’s impossible to maintain your new, slimmer figure without going back on phentermine. Thankfully, that’s NOT true. Still, if we’re being honest, keeping the weight off won’t be effortless either.
In this article we’ll talk frankly about what you need to know for life after phentermine, including proven tricks for weight maintenance and daily habits to keep you on the path to health!
Habits for Weight Maintenance
Losing weight is hard work. It’s an accomplishment that you should be able to show off for years to come! But, contrary to popular belief, the hard work isn’t over when you reach your goal weight.
About 80% of people who lose a significant amount of weight regain all or some of that weight within two years. The key to successful weight maintenance is to behave like the determined 20% who keep the weight off long term. Lucky for us, this is a heavily-studied topic and experts can offer some practical, concrete recommendations that will help you avoid re-gain.
In the US, there’s a group called the National Weight Control Registry (NWCR). This list keeps track of people have lost at least 30 pounds and kept it off for a full year or more. The registry is voluntary and currently tracks over 10,000 individuals. When experts analyzed the data gathered through NWCR questionnaires, certain patterns emerged in the daily routines of people who successfully maintain major weight loss. If you’re wondering how to keep the weight off during the ups and downs of life after phentermine, check out these six straightforward tips!
People successfully keep the weight off by choosing to:
1. Eat Breakfast
If you want to maintain major weight loss, eating breakfast proves key. But don’t stress – it doesn’t need to be anything fancy! The most common breakfast among NWCR participants is milk and cereal, but scrambled egg whites & toast, a smoothie or a meal replacement shake are great options too. The most important thing is that you eat (or drink) something. Aim for about 250-400 calories at this first meal.
2. Stick to a Healthy Diet
Have you heard people telling each other, “If you want something you’ve never had before, you have to do something you’ve never done before”? As cliché as it sounds, this advice holds amazingly true – as does the opposite. If you do what you’ve always done, you’ll end-up where you’ve always been. So, it’s important to stick with your new, healthier diet if you want to maintain your new, healthier weight. NWCR respondents report sticking to a low-fat, calorie-controlled diet long-term. Experts estimate that these maintainers eat about 1800 calories per day (when exercising) and avoid high-fat foods.
3. Cook at Home
Eating at home is healthier, and cheaper, than eating out. Studies show that home-cooked meals are almost always lower calorie, lower fat and lower in sodium as compared to restaurant meals. Moreover, diners who usually eat at home tend to eat less when they choose to eat out. People that lose a lot of weight and keep it off know this. Successful maintainers in the NWCR only eat out an average of 2.5 meals per week, and less than once a week at fast food restaurants.
4. Maintain Restraint
One reason people who successfully keep the weight off are able to stick with their healthy habits long-term is because they keep a “just lost weight” mindset. Instead of allowing themselves to slack, successful maintainers preserve their discipline. They stay highly motivated to eat right and get moving each day long after they’ve reached their goal weight.
The most successful maintainers hold onto this mindset even on weekends and holidays. This matters because these are the times when we’re most likely to binge or otherwise abandon healthy habits. To maintain major weight loss, healthy living should be a 24/7 endeavor.
5. Stay Active
It’s no secret that healthy diet and exercise work together in keeping your body healthy. So, it’s important to incorporate both into your daily routine to maintain weight loss. NWCR participants report fitting in an average of one hour per day of moderate exercise. Walking is the most common workout, but hiking, workout classes and water sports also prove popular. Anything works as long as you enjoy the activity and keep moving!
6. Weigh Regularly
Getting too attached to your scale is definitely controversial, but studies show that pesky machine plays a legitimate role in weight maintenance. The majority of those 20% that maintain their lower weight weigh daily, or at the very least weekly. Experts think this helps because it allows the individual to note small fluctuations in weight and adjust accordingly. If you weigh frequently, it’s much less likely that you’ll gain ten or fifteen pounds without noticing.
Preparing for Life After Phentermine
If you’re nervous about reaching the end of your phentermine prescription, routine and a strong support system will prove extra important in making your transition off the medication successful.
Establish Healthy Routines
During the final weeks of your phentermine prescription, make it a point to establish healthy routines based on the above tips. For example, if you aren’t normally a big breakfast person, take this opportunity to start incorporating a morning meal into your daily routine. Same goes for exercise. If you’re working out 3-4 times a week now, make an effort to increase this activity to 5-6 times per week. The lower your body weight, the less calories you need to function. So, if you’re working to permanently maintain a more slender figure, controlling intake and increasing activity are paramount.
Establishing routines also proves extremely helpful in a more general sense. While you still have the help of phentermine, start getting your body used to a set daily routine. If you’re already used to eating healthy meals and snacks, working out and sleeping at the same time each day, it will be much easier to control your appetite and energy levels post-phentermine. Wondering what a healthy routine looks like? Check out the example below!
Last, but definitely not least, seek out a strong support network. Did you know that obesity is medically considered a chronic condition? That’s because doctors, nurses, dietitians and the rest of the medical community understand that weight loss and maintenance is a life-long activity. None of us are 100% motivated all of the time, so seek-out a strong support system that will celebrate the victories and brave the lows with you.
This support can either be found in-person or online. If you have a friend, coworker or partner that will keep you accountable and help you navigate challenges that’s perfect! Check-in regularly with this person about your meals, workouts and life in general. It can be fun if you two (or a group of you) swap healthy recipes, explore new fitness classes, and offer each other emotional support when life gets tough.
If you don’t have that person (or you’re keeping phentermine a secret), consider seeking support in an online community. We maintain a number of lively communities that serve just this purpose for thousands of phentermine users every day!
