New research suggests that people who come off blockbuster GLP-1 drugs like semaglutide or tirzepatide can put back on lost weight far faster than those who stop conventional lifestyle programs.
Research printed in a major health publication shows that while overweight individuals often shed substantial amounts of their total mass while using the jabs, the mass is regained at an average rate of nearly a kilo each month upon discontinuation.
"Users using such drugs must be aware of the danger of quick weight regain when the treatment ends," stated researcher Dr. Susan Jebb.
That rate of recovery means a return to pre-treatment weight within about a year and a half.
Comparing Approaches
The research, which looked at dozens of studies involving thousands of patients, contrasted the outcomes of GLP-1 agonists with other pills.
The team emphasize that people who shed pounds through dieting usually experience a less rapid creep back—approximately 100 grams monthly—post-intervention.
The Reason for the Quick Rebound
Experts believe the way of the jabs accounts for the heightened weight return.
GLP-1 drugs mimic a natural hormone called GLP-1, which helps regulate appetite.
"Artificially providing the hormone concentrations several times higher than the body's typical production might result in the body to produce less of its endogenous hormone, and could diminish responsiveness to its actions," noted Dr. Adam Collins, a nutrition specialist.
"Stopping of this medication results in hunger is no longer kept in check, making excessive eating a significant risk."
A Chronic Condition?
The NHS suggest the jabs for individuals with weight-linked health risks, accompanied by recommended diet and exercise modifications.
A number of clinicians contend that, considering the significant potential of relapse, the treatment is often long-term.
This perspective is supported by drug manufacturers, who state that the findings "underscore the persistent nature of excess weight," akin to managing diseases like diabetes.
Patient Experiences
People who have discontinued the medication report a sudden resurgence of cravings.
"It was like something flipping and you become extremely hungry," recalled a patient.
This difficulty is compounded if individuals have not developed sustainable lifestyle or habit modifications during therapy.
Growing Interest
Figures show that millions of adults in the UK have used weight-loss jabs in the last 12 months, with demand continuing to grow.
- Use is more common among females than males.
- The 40s and 50s demographic shows the greatest level of interest.
- A large proportion access the medications through private prescriptions rather than public health services.
In conclusion, clinicians caution that while the jabs are powerful agents for shedding pounds, they are not a standalone fix and long-term success likely depends on integrated lifestyle support.
