New research indicates that individuals who come off new weight-loss injections like semaglutide or tirzepatide tend to recover shed pounds far faster than those who stop traditional lifestyle programs.
Findings released in a leading medical journal demonstrates that while obese individuals often shed about a fifth of their body weight while on the medication, the mass returns at an estimated rate of 0.8 kg per month once they quit.
"People using these treatments must be cognizant of the danger of fast rebound weight gain when the therapy ends," warns lead investigator Dr. Susan Jebb.
Such speed of recovery implies a return to original weight in about 18 months.
Weighing Treatments
The analysis, which reviewed 37 of trials involving over 9,000 of participants, contrasted the effects of the injectable medications with older methods.
Researchers emphasize that people who lose weight through lifestyle changes alone usually see a more gradual weight regain—approximately 0.1 kg a month—once they finish.
The Reason for the Fast Rebound
Doctors suggest the way of the injections is key to understanding the accelerated rebound.
GLP-1 drugs imitate a natural hormone called glucagon-like peptide-1, which moderates hunger.
"Artificially providing the hormone levels far above than the body's typical production might result in the system to generate a reduced amount of its endogenous GLP-1, and could lessen responsiveness to its actions," said Dr. Adam Collins, a nutrition expert.
"Discontinuation of this GLP-1 'fix' leads to hunger is no longer kept in check, making binge eating a significant risk."
An Ongoing Issue?
Medical guidelines suggest the injections for individuals with weight-linked health risks, accompanied by recommended diet and exercise modifications.
A number of clinicians say that, considering the significant potential of weight regain, the treatment should be considered life-long.
This view is echoed by pharmaceutical companies, who state that the results "highlight the long-term character of excess weight," comparing it to managing diseases like hypertension.
User Accounts
People who have come off the medication describe a powerful return of hunger.
"I experienced a trigger flipping and you become starving," recalled one woman.
This challenge is compounded if users have not developed permanent lifestyle or habit changes during treatment.
Significant Adoption
Figures show that a significant number of adults in the UK have used weight-loss jabs in the last 12 months, with desire remaining high.
- Adoption is more common among females compared to men.
- The middle-aged demographic shows the highest usage rates.
- A large proportion obtain the medications through private healthcare rather than the NHS.
In conclusion, experts emphasize that while these medications are effective tools for weight loss, they are not a magic cure and long-term success relies on combined lifestyle changes.
