Rapid adoption of GLP-1 therapies has transformed overweight and obesity treatment. About 1 in 8 adults (12%) say they use a GLP-1 medication for weight loss or to treat a chronic condition, and 18% say they have used a GLP-1 medication at some point. (1)
As use of GLP-1s for weight management grows, questions remain around what happens when treatment is discontinued. Early evidence demonstrates that weight regain is common after stopping GLP-1 use. (2) This underscores the importance of establishing sustainable lifestyle habits and a long-term maintenance plan early in the treatment journey.
Healthcare professionals are uniquely positioned to help patients successfully navigate the transition off GLP-1s. Tailored nutrition guidance, behavioral strategies and ongoing support will help patients sustain progress and avoid weight regain.
Read on to explore what happens after GLP-1 therapy ends and practical strategies to help patients maintain weight loss over time.
What Happens After GLP-1 Treatment Ends?
GLP-1 medications reduce food intake by slowing digestion and reducing appetite, which helps people feel fuller for longer. (3) As a result, people may feel satisfied with smaller portions or think about food less often. This ultimately results in weight loss.
Though leading health and nutrition organizations including the World Health Organization (WHO) support the use of GLP-1 therapies as a long-term obesity treatment, many still commonly approach their use as short-term medications. (4) A retrospective cohort study followed up with over 125,000 adults with overweight or obesity who had initiated GLP-1 treatment. After one year, nearly 54% of participants had discontinued treatment. (5) These results are consistent with other analyses.
When therapy is discontinued, appetite and hunger cues return as part of a normal biological response. Hunger-related hormones like ghrelin may rise again, making it more challenging to maintain weight loss. (6)
Weight regain is common. The STEP 1 trial extension followed more than 300 participants from around the world for one year after discontinuing GLP-1 treatment. They were evaluated for changes in body weight and cardiometabolic risk factors. At the study’s conclusion, participants regained about two-thirds of initial weight lost within a year of stopping GLP-1 treatment. (7)
Losing weight is just one part of the journey. Successfully maintaining weight loss over time requires realistic, sustainable strategies that are core to a person’s everyday routine.
What Does the Evidence Say About Weight Loss Maintenance?
Maintaining weight loss is difficult for most people, whether following a GLP-1 medication or not. A widely cited analysis of long-term studies found that most people regain about half the weight they lose within 2 years. By 5 years, that figure climbs above 80%. (8)
Some of the best data on long-term weight maintenance comes from the National Weight Control Registry. Established in 1994, this investigation has tracked more than 10,000 people who lost significant weight and kept it off, in some cases for decades. (9)
While participants have used a variety of approaches to lose weight, these lifestyle habits are common among successful weight maintainers:
- 78% eat breakfast every day.
- 62% watch less than 10 hours of TV per week - well below the national average.
- 75% weigh themselves at least once a week, with regular self-monitoring being one of the most common traits of success.
- 90% exercise for about 1 hour per day on average, combining cardio and strength training.
How to Help Patients Achieve Sustainable Weight Loss
There is no single approach to maintaining weight loss. Instead, consistent habits that support nutrition, physical activity and self-monitoring can help people work toward long-term weight-management goals.
Strategies to consider adopting during GLP-1 treatment and at discontinuation include:
- Prioritize nutrient-dense meals and snacks centered around protein and fiber.
- Consume moderate amounts of carbohydrate (~100 net carbohydrates per day), which has better long-term adherence and may be a better weight maintenance strategy.
- Choose water and higher-protein, low-sugar drinks for hydration.
- Exercise regularly to preserve lean muscle mass.
- Practice mindful eating by listening to hunger cues and avoiding distractions during mealtimes.
- Schedule regular check-ins between patients and practitioners to monitor weight, lifestyle behaviors and maintenance goals and adjust the plan when needed.
Practitioner support is essential for long-term success. In a 2025 joint statement from the American College of Lifestyle Medicine, the American Society for Nutrition, the Obesity Medicine Association, and The Obesity Society, organizations emphasize the importance of clinician-guided lifestyle interventions, particularly given medication adherence challenges. Nutritional and lifestyle counseling is recommended before, during, and after the weight reduction period. (10)
Framing Treatment as a Long-Term Commitment
GLP-1 discontinuation is common, and so is weight regain. This makes long-term weight management strategies an important part of the conversation. While research continues to evolve around the best strategies for maintenance after GLP-1 discontinuation, establishing a plan that incorporates lifestyle behaviors can help prepare patients should they transition off.
Healthcare professionals play an important role throughout the journey. Prioritize helping patients build individualized maintenance plans and provide ongoing support as needs and goals change over time. Beginning this conversation early on in treatment can help ensure patient success.
