Keeping Weight Off After GLP-1 Treatment: The Role of Exercise

Research on GLP-1 medications shows that weight often returns after treatment stops. It also shows that people who exercise regularly keep much more of it off.

What happens after treatment stops

In a follow-up to the STEP 1 semaglutide trial, researchers tracked 327 adults for one year after they stopped both the medication and the lifestyle program. During treatment, these participants had lost an average of 17% of their body weight. Within a year of stopping, they had regained about two-thirds of it, and most of the improvements in blood pressure and blood sugar had reversed.

The researchers concluded that obesity is a chronic condition and that most people need some form of ongoing support to maintain their results.

How exercise affects weight regain

A separate study followed people for one year after they completed one of four programs: exercise, a GLP-1 medication, both, or placebo.

  • People who had taken medication only regained the most weight.
  • People who had exercised kept their weight and body composition largely stable through the following year.
  • People who had done both were about 4 times more likely than the medication-only group to still be at least 10% below their starting weight one year later.

Participants exercised two to three times a week at an intensity that raised their heart rate and breathing, for a total of about two hours a week.

Habits that help maintain weight loss

  1. Schedule exercise like an appointment. Include both aerobic activity and strength training each week.
  2. Keep up strength training. Maintaining muscle helps the body maintain a healthy weight. Our article on protecting muscle while losing weight on a GLP-1 explains how.
  3. Plan your meals. Build meals around protein, vegetables and whole foods so your eating habits hold up when appetite returns.
  4. Keep your follow-up visits. Regular check-ins make it easier to catch small regains early.
  5. Talk to your provider before changing medication. Do not stop or adjust a prescribed medication on your own. Some people benefit from long-term treatment, and your provider can help you decide.

Frequently asked questions

Will I regain weight if I stop a GLP-1 medication?

Many people do. In the STEP 1 extension, people who stopped both the medication and their lifestyle program regained about two-thirds of the weight they had lost within a year.

Does exercise help keep weight off?

Yes. In a study that followed people for a year after treatment ended, those who had exercised kept their weight largely stable. Those who had combined exercise and medication were about 4 times more likely than the medication-only group to stay at least 10% below their starting weight.

Should I stop my medication on my own?

No. Do not stop or change a prescribed medication without talking to your provider first.

How much exercise helps?

In the study, people exercised two to three times a week at a level that raised their heart rate and breathing, about two hours a week in total. Your provider can help you decide what is safe for you.
