A recent study reveals that patients who come off blockbuster GLP-1 drugs like semaglutide or tirzepatide tend to recover shed pounds far faster than those who halt conventional diet and exercise programs.
Published data in a major health publication shows that while overweight people frequently drop a large proportion of their total mass while using the jabs, the weight is regained at an average rate of 0.8 kg per month once they quit.
"People purchasing such drugs need to be informed of the potential of rapid weight regain when the treatment ends," stated lead investigator Dr. Susan Jebb.
That rate of regain implies a reversion to starting weight within about one and a half years.
Analyzing Therapies
The research, which reviewed 37 of studies involving thousands of patients, contrasted the effects of the injectable medications with conventional dieting.
The team emphasize that people who lose weight through diet and exercise generally have a less rapid weight regain—approximately 100 grams monthly—once they finish.
Explaining the Rapid Regain
Experts suggest the mechanism of the injections accounts for the heightened rebound.
The injections imitate a body's own chemical called glucagon-like peptide-1, which controls feelings of fullness.
"Artificially providing the hormone levels far above than normal could lead to the body to generate a reduced amount of its own natural GLP-1, and could diminish responsiveness to its actions," noted Dr. Adam Collins, a nutrition researcher.
"Discontinuation of this medication results in appetite is no longer kept in check, making binge eating much more probable."
A Lifelong Condition?
Health authorities advise the injections for individuals with weight-linked medical conditions, accompanied by recommended diet and exercise modifications.
Many experts argue that, given the significant potential of weight regain, the therapy is often ongoing.
This perspective is reinforced by pharmaceutical companies, who note that the findings "emphasize the long-term character of excess weight," comparing it to managing conditions like high blood pressure.
User Experiences
Individuals who have come off the medication explain a intense return of hunger.
"It felt as if a trigger activating and you're instantly ravenous," said one woman.
The struggle is worsened if users have not adopted sustainable dietary or behavioural changes during treatment.
Growing Use
Figures show that millions of people in the UK have tried these injections in the past year, with desire continuing to grow.
- Use is more common among females compared to men.
- The middle-aged demographic shows the greatest level of interest.
- A large proportion obtain the drugs through private healthcare rather than public health services.
Finally, experts stress that while the jabs are powerful tools for weight loss, they are not a permanent cure and long-term success likely depends on combined lifestyle management.
