New research indicates that people who come off popular slimming jabs like Wegovy and Mounjaro may regain shed pounds far faster than those who halt conventional lifestyle programs.
Published data in a prominent medical journal points out that while obese individuals frequently drop substantial amounts of their total mass while using the jabs, the weight returns at an estimated rate of 0.8 kg per month once they quit.
"People purchasing such drugs need to be cognizant of the danger of rapid weight regain when the therapy ends," cautioned lead investigator Dr. Susan Jebb.
Such speed of regain implies a reversion to original weight within about a year and a half.
Comparing Therapies
The analysis, which examined 37 of trials involving over 9,000 of patients, compared the results of GLP-1 agonists with other pills.
The team point out that people who shed pounds through diet and exercise typically experience a more gradual creep back—perhaps 100 grams monthly—post-intervention.
Understanding the Fast Rebound
Experts believe the mode of action of the injections accounts for the accelerated rebound.
The injections mimic a natural hormone called glucagon-like peptide-1, which helps regulate appetite.
"Sustained high doses of GLP-1 levels far above than the body's typical production might result in the system to produce less of its own natural GLP-1, and could lessen sensitivity to its effects," said Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this medication leads to hunger is unsuppressed, making overeating a significant risk."
A Chronic Disease?
Health authorities recommend the jabs for individuals with obesity-related health risks, alongside recommended diet and exercise modifications.
A number of clinicians say that, considering the significant potential of weight regain, the treatment is often long-term.
This opinion is echoed by pharmaceutical companies, who note that the findings "highlight the persistent character of excess weight," comparing it to managing conditions like high blood pressure.
User Accounts
People who have stopped the jabs explain a intense return of cravings.
"I experienced a switch that goes on and I was suddenly starving," recalled an individual.
The struggle is compounded if individuals have not adopted permanent lifestyle or habit changes during treatment.
Significant Adoption
Recent estimates indicate that a significant number of adults in the UK have tried these injections in the past year, with interest being substantial.
- Adoption is more common among women than men.
- The middle-aged age group shows the greatest level of interest.
- A large proportion access the medications through private healthcare rather than public health services.
Ultimately, clinicians emphasize that while the jabs are effective agents for weight loss, they are not a magic fix and maintained weight loss relies on combined lifestyle support.
