New research indicates that people who stop using blockbuster slimming jabs like Wegovy and Mounjaro may regain shed pounds much more quickly than those who end traditional lifestyle regimens.
Research printed in a major medical journal points out that while overweight people often shed substantial amounts of their body weight while undergoing treatment, the mass comes back at an estimated rate of nearly a kilo each month after stopping.
"People buying these drugs must be informed of the danger of fast rebound weight gain when the treatment ends," warns lead investigator Dr. Susan Jebb.
This pace of recovery suggests a reversion to starting weight in about 18 months.
Weighing Approaches
The research, which examined 37 of studies involving over 9,000 of patients, contrasted the outcomes of GLP-1 agonists with other pills.
Scientists emphasize that individuals who lose weight through diet and exercise generally have a more gradual weight regain—approximately 100 grams monthly—once they finish.
Understanding the Rapid Rebound
Nutrition scientists propose the way of the jabs explains the heightened weight return.
The injections copy a body's own chemical called glucagon-like peptide-1, which helps regulate hunger.
"Long-term administration of GLP-1 concentrations several times higher than normal could lead to the system to produce less of its endogenous GLP-1, and may also lessen responsiveness to its actions," explained Dr. Adam Collins, a dietetics specialist.
"Stopping of this GLP-1 'fix' results in hunger is no longer kept in check, making excessive eating a significant risk."
A Chronic Disease?
Health authorities recommend the injections for people with weight-linked medical conditions, alongside recommended diet and exercise modifications.
Many experts say that, due to the significant potential of weight regain, the treatment should be considered life-long.
This perspective is echoed by drug manufacturers, who say that the findings "underscore the chronic nature of excess weight," akin to managing conditions like hypertension.
Patient Testimonies
Users who have come off the jabs describe a sudden resurgence of appetite.
"It was like a trigger that goes on and you're instantly extremely hungry," described a patient.
This challenge is compounded if patients have not developed permanent lifestyle or habit modifications during therapy.
Significant Interest
Figures suggest that millions of adults in the UK have tried these injections in the past year, with demand remaining high.
- Adoption is more common among females compared to males.
- The middle-aged demographic shows the highest usage rates.
- A large proportion access the drugs through private prescriptions rather than public health services.
Ultimately, experts caution that while the jabs are powerful tools for shedding pounds, they are not a magic cure and maintained weight loss hinges on integrated lifestyle management.
