A recent study indicates that patients who come off popular slimming jabs like semaglutide or tirzepatide can put back on reduced body mass far faster than those who end traditional diet and exercise plans.
Findings released in a major medical journal shows that while obese individuals frequently drop a large proportion of their total mass while undergoing treatment, the mass comes back at an average rate of nearly a kilo each month once they quit.
"People buying such medications should be informed of the risk of quick rebound weight gain when the treatment ends," stated lead investigator Dr. Susan Jebb.
Such speed of regain suggests a reversion to starting weight in about one and a half years.
Analyzing Therapies
The study, which looked at 37 of trials involving thousands of patients, compared the outcomes of GLP-1 agonists with older methods.
Scientists note that people who shed pounds through lifestyle changes alone usually experience a slower weight regain—approximately 0.1 kg a month—post-intervention.
Understanding the Fast Rebound
Experts believe the mechanism of the drugs is key to understanding the amplified regain.
The injections imitate a body's own chemical called GLP-1, which helps regulate feelings of fullness.
"Long-term administration of GLP-1 concentrations several times higher than normal could lead to the body to produce less of its endogenous GLP-1, and may also reduce sensitivity to its effects," noted Dr. Adam Collins, a nutrition researcher.
"Stopping of this GLP-1 'fix' means hunger is unsuppressed, making binge eating much more probable."
An Ongoing Disease?
Health authorities recommend the jabs for people with obesity-related medical conditions, accompanied by prescribed lifestyle changes.
Many experts argue that, given the significant potential of relapse, the treatment should be considered long-term.
This opinion is reinforced by drug manufacturers, who say that the findings "underscore the chronic character of obesity," similar to managing diseases like diabetes.
User Experiences
People who have stopped the medication explain a sudden resurgence of appetite.
"It felt as if something that goes on and you're instantly starving," described a patient.
This challenge is compounded if patients have not adopted lasting lifestyle or habit changes during treatment.
Widespread Adoption
Figures indicate that millions of adults in the UK have tried weight-loss jabs in the past year, with desire remaining high.
- Use is greater among women compared to men.
- The 40s and 50s demographic shows the highest level of interest.
- A large proportion access the drugs through private prescriptions rather than the NHS.
Finally, experts caution that while these medications are powerful agents for shedding pounds, they are not a magic fix and maintained weight loss hinges on ongoing lifestyle changes.
