New research reveals that people who discontinue popular GLP-1 drugs like semaglutide or tirzepatide tend to recover reduced body mass much more quickly than those who halt conventional diet and exercise regimens.
Published data in a leading medical journal points out that while overweight individuals frequently drop substantial amounts of their body weight while undergoing treatment, the weight comes back at an average rate of nearly a kilo each month once they quit.
"Individuals using such drugs need to be aware of the risk of quick weight regain when the treatment concludes," cautioned expert Dr. Susan Jebb.
This pace of recovery suggests a reversion to starting weight within about 18 months.
Weighing Therapies
The study, which reviewed 37 of studies involving thousands of patients, contrasted the effects of GLP-1 agonists with older methods.
The team emphasize that people who shed pounds through dieting generally see a slower creep back—perhaps 0.1 kg a month—post-intervention.
Explaining the Fast Rebound
Nutrition scientists suggest the mode of action of the drugs explains the amplified rebound.
These medications mimic a body's own chemical called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Artificially providing the hormone concentrations several times higher than normal might result in the body to generate a reduced amount of its own natural GLP-1, and could reduce responsiveness to its effects," explained Dr. Adam Collins, a dietetics expert.
"Stopping of this hormone supplement means appetite is uncontrolled, making overeating far more likely."
A Lifelong Issue?
Health authorities suggest the injections for people with weight-linked health risks, alongside recommended lifestyle changes.
Professionals say that, given the significant potential of weight regain, the therapy might need to be ongoing.
This opinion is echoed by drug manufacturers, who note that the results "emphasize the persistent nature of excess weight," similar to managing diseases like high blood pressure.
User Testimonies
Individuals who have stopped the jabs explain a sudden return of appetite.
"I experienced something that goes on and I was suddenly extremely hungry," said an individual.
The struggle is compounded if patients have not established lasting lifestyle or habit changes during therapy.
Growing Adoption
Recent estimates suggest that a significant number of adults in the UK have used weight-loss jabs in the past year, with interest remaining high.
- Use is more common among females compared to males.
- The 40s and 50s demographic shows the greatest usage rates.
- A large proportion access the medications through private healthcare rather than public health services.
In conclusion, clinicians stress that while these medications are potent tools for shedding pounds, they are not a magic solution and long-term success likely depends on combined behavioural changes.
