A recent study indicates that patients who come off popular slimming jabs like semaglutide or tirzepatide may regain reduced body mass far faster than those who halt conventional lifestyle regimens.
Research printed in a prominent medical journal demonstrates that while obese individuals can lose 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 need to be cognizant of the danger of quick rebound weight gain when the medication concludes," warns expert Dr. Susan Jebb.
That rate of regain means a reversion to starting weight within about a year and a half.
Weighing Approaches
The study, which reviewed dozens of trials involving over 9,000 of participants, compared the effects of GLP-1 agonists with other pills.
Researchers emphasize that people who lose weight through dieting usually experience a less rapid creep back—perhaps 100 grams monthly—after stopping.
Explaining the Fast Regain
Doctors suggest the way of the jabs explains the heightened rebound.
The injections copy a natural hormone called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Long-term administration of GLP-1 concentrations far above than normal could lead to the body to produce less of its own natural GLP-1, and could diminish responsiveness to its effects," said Dr. Adam Collins, a nutrition expert.
"Discontinuation of this hormone supplement means hunger is uncontrolled, making overeating far more likely."
An Ongoing Issue?
Health authorities suggest the injections for individuals with weight-linked medical conditions, accompanied by prescribed diet and exercise modifications.
A number of clinicians argue that, considering the significant potential of relapse, the therapy should be considered long-term.
This perspective is supported by pharmaceutical companies, who note that the findings "highlight the persistent character of excess weight," comparing it to managing conditions like diabetes.
User Testimonies
People who have discontinued the medication report a powerful return of appetite.
"I experienced a trigger activating and you're instantly ravenous," recalled an individual.
The struggle is compounded if patients have not established permanent lifestyle or habit changes during therapy.
Widespread Adoption
Recent estimates suggest that millions of people in the UK have tried weight-loss jabs in the past year, with interest being substantial.
- Use is higher among females than men.
- The middle-aged demographic shows the greatest usage rates.
- Many access the medications through private prescriptions rather than public health services.
Ultimately, researchers caution that while GLP-1 drugs are potent agents for weight loss, they are not a standalone cure and lasting health benefits hinges on integrated lifestyle changes.
