New research suggests that people who discontinue popular weight-loss injections like semaglutide or tirzepatide tend to recover shed pounds at a significantly accelerated pace than those who stop traditional diet and exercise plans.
Published data in a prominent health publication shows that while overweight individuals frequently drop substantial amounts of their total mass while using the jabs, the mass is regained at an average rate of nearly a kilo each month after stopping.
"People purchasing these drugs should be aware of the risk of fast rebound weight gain when the therapy ends," warns expert Dr. Susan Jebb.
That rate of regain implies a return to original mass in about 18 months.
Analyzing Approaches
The analysis, which examined 37 of trials involving over 9,000 of patients, contrasted the effects of these new drugs with other pills.
Scientists emphasize that individuals who shed pounds through lifestyle changes alone typically see a less rapid weight regain—approximately 0.1 kg a month—once they finish.
Understanding the Rapid Regain
Experts propose the mechanism of the drugs accounts for the accelerated regain.
The injections mimic a body's own chemical called GLP-1, which controls appetite.
"Artificially providing the hormone concentrations several times higher than normal could lead to the system to generate a reduced amount of its endogenous GLP-1, and may also reduce responsiveness to its effects," noted Dr. Adam Collins, a dietetics researcher.
"Stopping of this medication results in appetite is no longer kept in check, making binge eating much more probable."
A Lifelong Condition?
The NHS advise the jabs for people with obesity-related health risks, alongside prescribed lifestyle changes.
Professionals argue that, given the high risk of weight regain, the treatment is often long-term.
This opinion is reinforced by pharmaceutical companies, who state that the results "underscore the long-term nature of obesity," similar to managing conditions like diabetes.
User Accounts
Users who have stopped the medication describe a intense resurgence of cravings.
"It was like a trigger flipping and you're instantly starving," said one woman.
This challenge is exacerbated if individuals have not adopted lasting lifestyle or habit changes during treatment.
Widespread Interest
Figures show that a significant number of adults in the UK have used these injections in the last 12 months, with interest being substantial.
- Use is more common among females than males.
- The middle-aged age group shows the highest usage rates.
- Many access the medications through private prescriptions rather than public health services.
Ultimately, experts stress that while the jabs are potent tools for shedding pounds, they are not a standalone cure and lasting health benefits hinges on combined behavioural support.
