New research suggests that individuals who discontinue popular GLP-1 drugs like semaglutide or tirzepatide may regain lost weight much more quickly than those who stop conventional lifestyle plans.
Published data in a prominent health publication shows that while obese people often shed substantial amounts of their total mass while using the jabs, the weight returns at an average rate of nearly a kilo each month after stopping.
"People purchasing such medications must be cognizant of the potential of fast weight regain when the therapy concludes," cautioned expert Dr. Susan Jebb.
That rate of recovery implies a reversion to pre-treatment weight within about 18 months.
Comparing Approaches
The research, which reviewed 37 of studies involving over 9,000 of patients, contrasted the outcomes of these new drugs with conventional dieting.
The team emphasize that individuals who shed pounds through lifestyle changes alone usually have a more gradual creep back—approximately 100 grams monthly—once they finish.
The Reason for the Quick Rebound
Doctors propose the mode of action of the injections accounts for the heightened regain.
These medications imitate a natural hormone called GLP-1, which helps regulate feelings of fullness.
"Sustained high doses of GLP-1 concentrations several times higher than the body's typical production could lead to the body to generate a reduced amount of its own natural hormone, and could lessen sensitivity to its effects," said Dr. Adam Collins, a dietetics researcher.
"Stopping of this medication leads to appetite is unsuppressed, making binge eating much more probable."
A Chronic Condition?
Medical guidelines suggest the injections for people with obesity-related medical conditions, accompanied by recommended diet and exercise modifications.
Many experts say that, considering the high risk of weight regain, the treatment should be considered ongoing.
This opinion is supported by pharmaceutical companies, who note that the findings "underscore the chronic nature of excess weight," similar to managing conditions like diabetes.
User Accounts
Individuals who have discontinued the medication explain a powerful return of appetite.
"It felt as if a trigger flipping and I was suddenly starving," recalled one woman.
The struggle is exacerbated if individuals have not adopted lasting lifestyle or habit changes during therapy.
Growing Use
Figures indicate that millions of adults in the UK have tried these injections in the past year, with desire remaining high.
- Use is more common among females compared to men.
- The 40s and 50s demographic shows the greatest level of interest.
- Many obtain the medications through private healthcare rather than the NHS.
In conclusion, experts caution that while the jabs are effective agents for weight loss, they are not a magic fix and long-term success hinges on integrated behavioural changes.
