A recent study indicates that patients who stop using new GLP-1 drugs like semaglutide or tirzepatide can put back on reduced body mass much more quickly than those who end conventional diet and exercise regimens.
Published data in a major health publication demonstrates that while overweight people frequently drop substantial amounts of their body weight while undergoing treatment, the weight is regained at an average rate of nearly a kilo each month once they quit.
"Individuals purchasing such medications should be aware of the risk of rapid weight regain when the medication ends," stated lead investigator Dr. Susan Jebb.
Such speed of recovery implies a return to starting mass within about a year and a half.
Comparing Approaches
The research, which looked at 37 of trials involving over 9,000 of patients, compared the effects of GLP-1 agonists with other pills.
Scientists emphasize that individuals who shed pounds through lifestyle changes alone usually see a less rapid weight regain—approximately 100 grams monthly—once they finish.
The Reason for the Fast Rebound
Doctors believe the mechanism of the jabs accounts for the accelerated regain.
GLP-1 drugs copy a natural hormone called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Sustained high doses of GLP-1 concentrations far above than normal may cause the body to produce less of its own natural hormone, and could lessen sensitivity to its effects," explained Dr. Adam Collins, a nutrition specialist.
"Discontinuation of this GLP-1 'fix' leads to hunger is no longer kept in check, making binge eating a significant risk."
A Chronic Condition?
Health authorities advise the jabs for individuals with weight-linked health risks, alongside prescribed diet and exercise modifications.
Professionals say that, considering the high risk of relapse, the treatment should be considered ongoing.
This view is reinforced by drug manufacturers, who note that the results "underscore the long-term character of obesity," similar to managing conditions like diabetes.
User Testimonies
Individuals who have stopped the jabs report a sudden return of appetite.
"It felt as if a trigger that goes on and you become ravenous," described a patient.
This challenge is worsened if individuals have not developed sustainable lifestyle or habit changes during therapy.
Widespread Adoption
Figures indicate that millions of adults in the UK have used these injections in the past year, with desire continuing to grow.
- Adoption is more common among females compared to men.
- The middle-aged age group shows the highest usage rates.
- A large proportion obtain the medications through private prescriptions rather than the NHS.
Ultimately, researchers stress that while the jabs are powerful tools for shedding pounds, they are not a standalone solution and maintained weight loss likely depends on combined lifestyle changes.
