Fresh analysis indicates that people who come off popular GLP-1 drugs like semaglutide or tirzepatide may regain reduced body mass far faster than those who end traditional lifestyle plans.
Research printed in a major health publication points out that while overweight 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 once they quit.
"Individuals using these medications should be informed of the potential of fast rebound weight gain when the therapy ends," stated lead investigator Dr. Susan Jebb.
Such speed of recovery means a return to original weight in about one and a half years.
Analyzing Therapies
The research, which reviewed 37 of studies involving thousands of patients, compared the effects of these new drugs with older methods.
The team emphasize that individuals who shed pounds through dieting generally see a more gradual weight regain—around 100 grams monthly—once they finish.
Explaining the Quick Rebound
Doctors believe the mode of action of the injections accounts for the accelerated regain.
These medications copy a body's own chemical called GLP-1, which helps regulate feelings of fullness.
"Artificially providing the hormone levels several times higher than normal might result in the system to generate a reduced amount of its own natural GLP-1, and may also diminish responsiveness to its actions," noted Dr. Adam Collins, a nutrition expert.
"Stopping of this hormone supplement leads to appetite is uncontrolled, making binge eating far more likely."
A Lifelong Issue?
Medical guidelines recommend the jabs for individuals with weight-linked health risks, alongside recommended lifestyle changes.
Professionals contend that, considering the significant potential of relapse, the therapy might need to be ongoing.
This view is echoed by drug manufacturers, who say that the results "highlight the long-term character of obesity," akin to managing diseases like high blood pressure.
User Experiences
People who have come off the jabs explain a intense resurgence of appetite.
"It felt as if something flipping and you're instantly starving," said a patient.
This challenge is worsened if patients have not established lasting lifestyle or habit modifications during therapy.
Widespread Interest
Figures indicate that millions of adults in the UK have used weight-loss jabs in the past year, with interest remaining high.
- Use is greater among women than men.
- The middle-aged age group shows the highest level of interest.
- A large proportion access the drugs through private prescriptions rather than the NHS.
Finally, experts caution that while GLP-1 drugs are effective tools for shedding pounds, they are not a standalone fix and long-term success hinges on ongoing lifestyle management.
