Life After Phentermine

Life After Phentermine

No one would deny that losing weight is hard work, but, contrary to popular belief, the hard work isn’t over when you reach your goal weight.

So, for patients nearing the end of their prescription, it’s important to consider life after phentermine: the sustainability of their wellness routine, potential phentermine withdrawal symptoms, how to avoid rebound weight gain, and where to turn for support.

How to NOT Gain Weight After Stopping Phentermine

The best way to avoid weight gain after phentermine is to establish, and commit to, healthy routines long-term.

About 80% of people who lose a significant amount of weight regain all or some of that weight within two years ( 1 ).

So what do those 20% of people do to keep the weight off long term?

The National Weight Control Registry (NWCR) offers some insight. This voluntary program tracks US residents who have lost 30 pounds or more and kept it off for a year or more, and currently contains more than 10,000 participants ( 2 ). When experts analyzed NWCR questionnaire data, certain patterns emerged.

People who successfully keep the weight off choose to ( 3 ):

1. Eat Breakfast

Eating breakfast is key to maintaining major weight loss.

Thankfully, it doesn’t need to be anything fancy. The most common breakfast among NWCR participants was milk and cereal but scrambled egg whites & toast, a smoothie, or a meal replacement shake are all great options too.

Takeaway: Eat or drink something in the first 1-2 hours after you wake up. Aim for 250-400 calories at breakfast.

2. Stick to a Healthy Diet

To avoid weight gain after phentermine, it is important to maintain a nutritious diet.

NWCR respondents stick to a low-fat, calorie-controlled diet long-term. Experts estimate that these weight maintainers eat an average of 1800 calories per day (when exercising) and avoid high-fat foods.

Takeaway: Keep an eye on calories and fat even after you reach your goal weight.

3. Cook at Home

Eating at home is healthier and cheaper than eating out. Plus, studies show that home-cooked meals are lower calorie, lower fat, and lower in sodium, on average, as compared to restaurant meals.

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.

Takeaway: Eat at home to save money and your waistline.

4. Maintain Restraint​

People who successfully keep the weight off the stick with their healthy habits long-term by retaining a “just lost weight” mindset.

Instead of allowing themselves to slack, successful maintainers stay disciplined about their diet and exercise habits. The most successful maintainers hold onto this mindset even on weekends and holidays.

Takeaway: To avoid weight regain, stay highly committed to healthy daily habits.

5. Stay Active​

Healthy food and regular exercise work together to keep your body healthy. So, it is important to incorporate both into your daily routine.

NWCR participants report doing an average of one hour per day of moderate exercise. Walking is the most common workout, but hiking, dancing, workout classes, and water sports are also popular.

Takeaway: Stay active. Aim for at least 60 minutes of exercise per day.

6. Weigh Regularly

Weighing daily is undoubtedly controversial, but studies show that balance plays a legitimate role in weight maintenance.

The majority of people who keep the weight off weigh daily, or at the very least weekly. Experts think this helps because it helps you notice small fluctuations in weight and adjust accordingly.

Takeaway: Weigh daily to keep your weight in check.
