New research reveals that individuals who stop using blockbuster slimming jabs like Wegovy and Mounjaro tend to recover shed pounds at a significantly accelerated pace than those who end traditional diet and exercise programs.
Published data in a leading medical journal demonstrates that while obese people can lose a large proportion of their total mass while using the jabs, the mass comes back at an average rate of 0.8 kg per month upon discontinuation.
"Individuals purchasing such medications should be aware of the danger of rapid weight regain when the treatment concludes," stated expert Dr. Susan Jebb.
This pace of regain implies a reversion to starting weight in about a year and a half.
Comparing Approaches
The study, which reviewed dozens of trials involving over 9,000 of patients, contrasted the effects of GLP-1 agonists with conventional dieting.
Scientists emphasize that individuals who shed pounds through dieting generally have a slower creep back—approximately 0.1 kg a month—once they finish.
Understanding the Fast Rebound
Nutrition scientists suggest the mechanism of the jabs explains the heightened weight return.
The injections copy a natural hormone called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Long-term administration of the hormone levels several times higher than normal could lead to the system to generate a reduced amount of its endogenous GLP-1, and may also diminish sensitivity to its actions," said Dr. Adam Collins, a dietetics expert.
"Discontinuation of this GLP-1 'fix' results in hunger is no longer kept in check, making overeating far more likely."
A Lifelong Disease?
The NHS recommend the jabs for individuals with weight-linked medical conditions, accompanied by recommended diet and exercise modifications.
A number of clinicians argue that, considering the likelihood of weight regain, the treatment might need to be ongoing.
This view is echoed by pharmaceutical companies, who say that the findings "highlight the chronic nature of obesity," comparing it to managing conditions like diabetes.
User Accounts
Individuals who have stopped the jabs explain a powerful resurgence of appetite.
"I experienced a trigger that goes on and you become starving," said a patient.
This challenge is exacerbated if patients have not developed lasting lifestyle or habit changes during treatment.
Significant Use
Survey data suggest that a significant number of adults in the UK have used these injections in the last 12 months, with desire remaining high.
- Use is greater among women compared to men.
- The 40s and 50s demographic shows the highest usage rates.
- A large proportion obtain the drugs through private healthcare rather than public health services.
Ultimately, researchers stress that while the jabs are effective agents for shedding pounds, they are not a standalone solution and long-term success likely depends on integrated lifestyle management.
