Fresh analysis reveals that individuals who discontinue new GLP-1 drugs like Wegovy and Mounjaro can put back on shed pounds far faster than those who halt conventional diet and exercise programs.
Published data in a prominent health publication demonstrates that while obese people often shed a large proportion of their total mass while undergoing treatment, the mass comes back at an estimated rate of 0.8 kg per month once they quit.
"People purchasing these treatments must be cognizant of the danger of fast rebound weight gain when the treatment ends," stated expert Dr. Susan Jebb.
Such speed of recovery implies a reversion to original weight within about one and a half years.
Weighing Treatments
The study, which reviewed dozens of studies involving over 9,000 of patients, compared the results of the injectable medications with other pills.
Scientists note that people who lose weight through dieting generally see a slower weight regain—perhaps 100 grams monthly—post-intervention.
Explaining the Fast Rebound
Nutrition scientists suggest the mode of action of the injections is key to understanding the accelerated rebound.
These medications mimic a natural hormone called glucagon-like peptide-1, which controls appetite.
"Artificially providing the hormone levels far above than normal might result in the system to produce less of its endogenous hormone, and may also lessen responsiveness to its actions," said Dr. Adam Collins, a nutrition specialist.
"Discontinuation of this hormone supplement means appetite is uncontrolled, making overeating a significant risk."
A Lifelong Disease?
Health authorities recommend the injections for individuals with obesity-related medical conditions, alongside recommended lifestyle changes.
Professionals argue that, due to the significant potential of weight regain, the treatment should be considered long-term.
This opinion is echoed by drug manufacturers, who say that the results "highlight the long-term character of excess weight," comparing it to managing conditions like hypertension.
User Testimonies
People who have discontinued the jabs describe a intense resurgence of hunger.
"It felt as if something flipping and you become extremely hungry," recalled one woman.
This difficulty is worsened if individuals have not developed sustainable lifestyle or habit changes during treatment.
Widespread Use
Figures indicate that a significant number of adults in the UK have used weight-loss jabs in the past year, with interest being substantial.
- Use is higher among women than men.
- The 40s and 50s demographic shows the highest usage rates.
- A large proportion access the drugs through private prescriptions rather than the NHS.
Ultimately, clinicians stress that while these medications are potent agents for shedding pounds, they are not a standalone fix and maintained weight loss relies on combined behavioural management.
