New research suggests that people who discontinue popular GLP-1 drugs like semaglutide or tirzepatide may regain reduced body mass far faster than those who stop traditional lifestyle regimens.
Research printed in a major health publication points out that while obese individuals frequently drop a large proportion of their body weight while undergoing treatment, the weight comes back at an average rate of 0.8 kg per month after stopping.
"Individuals buying these medications need to be cognizant of the risk of quick weight regain when the therapy concludes," warns researcher Dr. Susan Jebb.
That rate of recovery means a reversion to pre-treatment mass in about one and a half years.
Analyzing Approaches
The analysis, which examined dozens of trials involving thousands of participants, compared the outcomes of the injectable medications with conventional dieting.
Scientists emphasize that individuals who shed pounds through diet and exercise generally experience a less rapid weight regain—around 100 grams monthly—after stopping.
Explaining the Fast Rebound
Experts believe the mechanism of the jabs accounts for the heightened weight return.
The injections mimic a body's own chemical called GLP-1, which controls appetite.
"Sustained high doses of the hormone levels far above than the body's typical production could lead to the body to generate a reduced amount of its own natural GLP-1, and could reduce responsiveness to its actions," explained Dr. Adam Collins, a nutrition expert.
"Discontinuation of this medication results in appetite is unsuppressed, making binge eating a significant risk."
A Lifelong Condition?
Medical guidelines suggest the injections for people with obesity-related health risks, alongside prescribed lifestyle changes.
Many experts contend that, considering the significant potential of relapse, the therapy is often life-long.
This view is reinforced by pharmaceutical companies, who say that the findings "emphasize the long-term character of obesity," similar to managing diseases like diabetes.
Patient Testimonies
People who have come off the jabs report a powerful return of cravings.
"It was like something activating and you become extremely hungry," said an individual.
This challenge is exacerbated if individuals have not developed permanent dietary or behavioural modifications during treatment.
Widespread Interest
Figures suggest that a significant number of people in the UK have used these injections in the past year, with interest remaining high.
- Use is greater among women compared to men.
- The 40s and 50s age group shows the highest level of interest.
- A large proportion access the medications through private prescriptions rather than public health services.
Finally, clinicians emphasize that while the jabs are potent tools for shedding pounds, they are not a magic solution and long-term success hinges on ongoing lifestyle changes.
