To maintain weight loss after a GLP-1, the consensus sources point to the same few habits: regular physical activity including muscle strengthening, an eating pattern you can realistically keep, weekly weigh-ins, and ongoing support. None of these is a guarantee. Studies of people who stopped GLP-1 medicines show that regaining weight is common, and no habit list reverses that for everyone. This guide restates what NIDDK, the CDC and a joint advisory from four US societies say, so you can build a plan with your prescriber.

Start with the honest baseline

The numbers behind the problem are in what happens when you stop taking a GLP-1. In short, in the STEP 1 extension, people who stopped semaglutide 2.4 mg regained about two-thirds of their weight loss within a year. A 2026 BMJ meta-analysis of weight management medicines found average regain of 0.4 kg per month after stopping, and regain that was faster after medication than after behavioral programs, by 0.3 kg per month.

That is the reason to treat maintenance as a plan with support, not a matter of willpower. Whether you stop, continue or change a medicine is a decision for you and your prescriber. Everything below is general information that applies whether or not you are still on treatment.

What the consensus sources say

Keep moving, in a way you can sustain

NIDDK, part of the US National Institutes of Health, says a plan for keeping weight off should include 150 to 300 minutes or more of physical activity per week. The CDC’s tips for keeping weight off suggest 60 to 90 minutes of moderate-intensity activity most days, which can be split into shorter bouts such as 20 to 30 minutes three times a day. Those two figures differ, and both are general guidance for adults. Ask your clinician what is reasonable for your health and fitness, and build up gradually.

Add strength training

The CDC’s adult activity guidance says adults need 2 days of muscle-strengthening activity each week, on top of aerobic activity. The joint advisory on nutrition during GLP-1 therapy, from the American College of Lifestyle Medicine, the American Society for Nutrition, the Obesity Medicine Association and The Obesity Society, lists adequate protein and strength training to preserve lean mass among its eight priorities. For more on that topic, see protein on a GLP-1 and GLP-1 and muscle loss.

Choose an eating pattern you can repeat

The CDC advises following a healthy and realistic eating pattern and avoiding getting over-hungry and overeating. The joint advisory calls for personalized, nutrient-dense, minimally processed diets. Neither source prescribes one diet for everyone. Our GLP-1 diet guide covers food choices in more detail, and a dietitian can tailor a pattern to you.

The advisory’s summary also states that patients who had structured nutrition guidance alongside GLP-1 therapy had greater weight loss, better adherence and were more likely to sustain weight loss after discontinuing medication than patients on medication alone. That is a finding about support, not about a specific diet.

Weigh in weekly and track a few habits

NIDDK recommends monitoring your weight at least once a week as part of a maintenance plan. The CDC suggests weighing yourself once a week, and recording steps, physical activity and fruit and vegetable intake, so you can spot patterns early. If weighing is stressful for you, tell your clinician.

Line up support

NIDDK advises looking for a program that gives ongoing support, such as counseling sessions, for keeping the weight off. The CDC suggests relying on friends or partners who are pursuing similar goals. The joint advisory also names activity, sleep, stress, substance use and social connections as areas to address for long-term success.

A simple weekly check-in

This is one way to put the sources into practice, not a protocol.

  1. Same day each week: weigh in and write it down.
  2. Count the sessions: how many days of activity, and how many of strength training.
  3. Note the basics: meals you could repeat, sleep, stress, and anything that felt hard.
  4. Compare over weeks, not days. Single readings move for many reasons.
  5. Bring the log to your appointments. Agree with your prescriber in advance on what changes in weight or other measurements should prompt a call.

When to call a clinician

Contact your prescriber or another clinician if your weight, blood pressure or blood sugar numbers change in ways that worry you, if eating or weighing is causing distress, or if you are unsure how to begin exercising safely.

If you are still taking a GLP-1 pen, the Medication Guides for Wegovy, Ozempic and Zepbound say to stop the medicine and call your healthcare provider right away for severe stomach pain that will not go away, with or without vomiting. Your prescriber and pharmacist set your plan.

Frequently asked questions

How do I maintain weight loss after Zepbound or Mounjaro?

The general principles above apply regardless of the product: activity, strength training, a repeatable eating pattern, weekly weigh-ins and support. A medication-specific plan, including whether to stay on treatment, is for your prescriber. For what trials found after tirzepatide was stopped, read what happens when you stop taking a GLP-1.

How much exercise do I need to keep weight off?

NIDDK mentions 150 to 300 minutes or more per week, and the CDC suggests 60 to 90 minutes of moderate-intensity activity most days. Both are general adult guidance. Start where you are and ask your clinician about a safe ramp-up.

Should I weigh myself every day?

NIDDK says to monitor your weight at least once a week, and the CDC suggests once a week. A weekly pattern is easier to read than daily ups and downs. If weighing affects your mood, say so to your clinician.

Will the weight come back anyway?

Group averages in the studies show regain is common after stopping, which is why a plan with support matters. Averages do not predict any one person, and habits are one part of a larger picture that includes your prescriber’s guidance.

Keep the habits visible

Dosinha’s weight log, water log and protein targets are free, and the shot log keeps your treatment history in one place for appointments. You can use them to keep a record and notice patterns to share with your prescriber. The app does not prevent weight regain or tell you what to do about your medicine. Try the free tools.
