New research reveals that patients who come off new slimming jabs like semaglutide or tirzepatide tend to recover reduced body mass at a significantly accelerated pace than those who halt traditional diet and exercise regimens.
Findings released in a major medical journal demonstrates that while obese individuals often shed a large proportion of their body weight while on the medication, the mass returns at an estimated rate of nearly a kilo each month after stopping.
"People using such treatments should be cognizant of the risk of quick weight regain when the treatment ends," stated lead investigator Dr. Susan Jebb.
That rate of recovery means a return to starting weight within about 18 months.
Analyzing Therapies
The analysis, which looked at dozens of studies involving thousands of participants, compared the results of the injectable medications with other pills.
The team emphasize that people who shed pounds through lifestyle changes alone typically see a more gradual weight regain—around 100 grams monthly—once they finish.
Understanding the Quick Rebound
Experts believe the mode of action of the drugs is key to understanding the heightened rebound.
The injections mimic a natural hormone called glucagon-like peptide-1, which helps regulate hunger.
"Artificially providing GLP-1 levels far above than normal may cause the system to generate a reduced amount of its own natural hormone, and could diminish responsiveness to its effects," said Dr. Adam Collins, a dietetics researcher.
"Stopping of this GLP-1 'fix' results in appetite is no longer kept in check, making binge eating a significant risk."
A Chronic Disease?
Health authorities recommend the jabs for individuals with weight-linked health risks, alongside recommended diet and exercise modifications.
A number of clinicians argue that, considering the likelihood of relapse, the therapy is often life-long.
This opinion is echoed by drug manufacturers, who state that the results "highlight the chronic character of obesity," akin to managing conditions like diabetes.
Patient Testimonies
Individuals who have discontinued the medication report a powerful resurgence of cravings.
"It was like something flipping and you become extremely hungry," said an individual.
This challenge is worsened if individuals have not adopted lasting lifestyle or habit changes during therapy.
Significant Use
Survey data indicate that a significant number of adults in the UK have tried these injections in the past year, with demand being substantial.
- Use is more common among women than males.
- The middle-aged demographic shows the highest usage rates.
- Many access the medications through private healthcare rather than public health services.
Ultimately, researchers caution that while these medications are effective agents for shedding pounds, they are not a magic solution and long-term success hinges on ongoing lifestyle support.
