Fresh analysis reveals that patients who stop using new weight-loss injections like semaglutide or tirzepatide tend to recover shed pounds far faster than those who end conventional diet and exercise programs.
Published data in a leading health publication points out that while overweight individuals frequently drop substantial amounts of their body weight while undergoing treatment, the mass returns at an average rate of 0.8 kg per month after stopping.
"Users purchasing these treatments need to be cognizant of the potential of rapid rebound weight gain when the therapy ends," warns researcher Dr. Susan Jebb.
That rate of recovery suggests a return to original weight within about one and a half years.
Analyzing Approaches
The research, which examined 37 of trials involving over 9,000 of participants, contrasted the results of the injectable medications with conventional dieting.
The team point out that people who lose weight through dieting generally experience a more gradual creep back—perhaps 0.1 kg a month—post-intervention.
The Reason for the Fast Rebound
Experts propose the mechanism of the jabs is key to understanding the amplified rebound.
The injections imitate a body's own chemical called GLP-1, which controls hunger.
"Long-term administration of GLP-1 levels several times higher than normal may cause the body to produce less of its own natural hormone, and could lessen sensitivity to its actions," said Dr. Adam Collins, a nutrition expert.
"Withdrawal of this medication leads to hunger is unsuppressed, making overeating much more probable."
A Lifelong Condition?
Medical guidelines recommend the injections for individuals with weight-linked health risks, alongside recommended diet and exercise modifications.
A number of clinicians argue that, given the high risk of relapse, the treatment should be considered ongoing.
This view is reinforced by drug manufacturers, who say that the findings "underscore the chronic character of excess weight," similar to managing conditions like hypertension.
User Testimonies
Users who have stopped the medication report a powerful resurgence of appetite.
"It felt as if a trigger flipping and you're instantly starving," recalled one woman.
The struggle is exacerbated if individuals have not developed sustainable dietary or behavioural modifications during treatment.
Widespread Interest
Figures show that a significant number of adults in the UK have tried weight-loss jabs in the past year, with demand remaining high.
- Use is higher among women compared to males.
- The 40s and 50s age group shows the highest usage rates.
- A large proportion obtain the medications through private prescriptions rather than the NHS.
Ultimately, clinicians emphasize that while these medications are effective tools for shedding pounds, they are not a standalone fix and lasting health benefits relies on combined lifestyle changes.
