A recent study indicates that people who stop using new GLP-1 drugs like semaglutide or tirzepatide may regain shed pounds far faster than those who end conventional lifestyle regimens.
Published data in a prominent health publication demonstrates that while obese people can lose substantial amounts of their total mass while undergoing treatment, the weight returns at an average rate of nearly a kilo each month after stopping.
"Individuals purchasing such drugs need to be aware of the danger of fast weight regain when the medication concludes," warns researcher Dr. Susan Jebb.
This pace of regain implies a reversion to pre-treatment mass within about a year and a half.
Comparing Therapies
The research, which looked at dozens of studies involving over 9,000 of patients, compared the effects of GLP-1 agonists with other pills.
The team emphasize that individuals who lose weight through lifestyle changes alone generally have a slower weight regain—approximately 100 grams monthly—post-intervention.
Explaining the Quick Rebound
Experts propose the mode of action of the jabs accounts for the accelerated rebound.
GLP-1 drugs imitate a body's own chemical called glucagon-like peptide-1, which controls feelings of fullness.
"Sustained high doses of GLP-1 levels several times higher than the body's typical production might result in the system to produce less of its own natural hormone, and may also lessen responsiveness to its effects," explained Dr. Adam Collins, a dietetics specialist.
"Stopping of this GLP-1 'fix' results in hunger is no longer kept in check, making excessive eating much more probable."
A Chronic Condition?
Medical guidelines suggest the jabs for individuals with obesity-related health risks, accompanied by prescribed diet and exercise modifications.
Professionals say that, considering the significant potential of weight regain, the therapy should be considered long-term.
This opinion is supported by drug manufacturers, who note that the findings "highlight the long-term character of excess weight," similar to managing conditions like high blood pressure.
User Experiences
People who have stopped the jabs explain a powerful resurgence of appetite.
"It was like a trigger flipping and you're instantly extremely hungry," said an individual.
This difficulty is exacerbated if individuals have not established permanent dietary or behavioural changes during therapy.
Widespread Interest
Recent estimates show that millions of people in the UK have tried these injections in the last 12 months, with desire continuing to grow.
- Adoption is greater among women compared to males.
- The 40s and 50s age group shows the greatest usage rates.
- Many obtain the medications through private prescriptions rather than public health services.
Finally, experts stress that while the jabs are potent agents for weight loss, they are not a permanent solution and long-term success hinges on ongoing behavioural changes.
