Coming off a GLP-1: what research shows and habits that help

People think about coming off a GLP-1 for many reasons, from cost and side effects to reaching a goal. This guide doesn’t tell you whether or how to stop; it covers what research shows and the habits that help.

Who should I talk to first?

Your prescriber, before changing anything about your medication.

They can help you weigh your options, plan how any change happens, set up follow-up, and consider other health conditions.

What happens to weight after stopping?

In one major trial, people regained about two-thirds of the weight they had lost within a year.

In STEP 1, adults took weekly semaglutide with a lifestyle program for 68 weeks. Then both stopped, and a group was followed for another year (Wilding et al., 2022).

The average regain was 11.6 percentage points. The structured lifestyle support also ended, which may have contributed. The researchers say the findings reflect the long-term nature of obesity and suggest ongoing care is needed. A 2025 joint advisory (ACLM, ASN, OMA and TOS) agrees: when GLP-1 medications are stopped, weight regain is common.

What does this mean for me?

These are averages, and regain isn’t a personal failure.

Obesity is a long-term condition that often needs ongoing care, whether medication, other care from your doctor, or a mix. Habits still matter too. The NIDDK notes you will probably regain some weight after stopping, and that healthy eating and more activity may help you regain less or keep it off.

Which habits are worth building now?

Protein at meals, strength training, regular whole-food meals and a planned week.

Keep protein at every meal

It helps you feel satisfied and supports your muscles. The advisory suggests 1.2 to 1.6 grams per kilogram of body weight per day during weight loss. See how much protein you need.

Keep strength training

The advisory suggests strength training at least 3 times a week plus at least 150 minutes of moderate aerobic activity. The Physical Activity Guidelines for Americans recommend 150 to 300 minutes of moderate activity and muscle-strengthening at least 2 days a week. See protecting muscle.

Eat regular meals built on whole foods

Fruits, vegetables, whole grains, dairy, lean proteins, nuts, seeds and plant oils, at consistent times, with little refined grain, added sugar or fast food.

Plan your week

Meals already decided mean fewer in-the-moment choices. A grocery list helps.

Know your maintenance calories

Your energy needs change once weight loss isn’t the goal. The calorie calculator gives a starting estimate, and a registered dietitian can fine-tune it.

What if my appetite comes back?

Eat regular meals, lead with protein and fiber, and start with smaller portions.

The advisory describes these medications as reducing hunger and “food noise” while people take them, so this may shift afterward.

Long gaps can leave you overly hungry. Protein and fiber help meals feel satisfying. Hunger is simply information, so notice it without judging.

What support can I keep?

Your doctor, a registered dietitian and a plan with your prescriber.

Plan with your prescriber what to do if weight starts to return. The advisory recommends pairing GLP-1 use with dietitian counseling, and that support can continue after your medication changes.

Whatever you decide, every meal you plan and every habit you keep is still yours. Imi plans meals like this for you each week, on or off medication. For the full picture, see eating well on a GLP-1.
