New research suggests that patients who come off blockbuster GLP-1 drugs like Wegovy and Mounjaro can put back on reduced body mass at a significantly accelerated pace than those who end conventional diet and exercise programs.
Research printed in a prominent health publication shows that while overweight individuals often shed substantial amounts of their total mass while using the jabs, the weight returns at an estimated rate of 0.8 kg per month upon discontinuation.
"Individuals buying these medications should be informed of the potential of rapid weight regain when the therapy is stopped," warns expert Dr. Susan Jebb.
That rate of regain suggests a reversion to pre-treatment weight within about a year and a half.
Analyzing Treatments
The study, which examined dozens of trials involving over 9,000 of participants, compared the outcomes of GLP-1 agonists with conventional dieting.
The team note that people who lose weight through diet and exercise generally experience a less rapid weight regain—around 0.1 kg a month—once they finish.
Explaining the Rapid Regain
Experts propose the way of the jabs explains the amplified weight return.
The injections mimic a natural hormone called glucagon-like peptide-1, which controls hunger.
"Artificially providing GLP-1 concentrations several times higher than normal might result in the system to produce less of its endogenous GLP-1, and could lessen sensitivity to its effects," noted Dr. Adam Collins, a dietetics researcher.
"Withdrawal of this hormone supplement leads to hunger is no longer kept in check, making overeating far more likely."
A Chronic Condition?
Health authorities recommend the jabs for people with weight-linked medical conditions, accompanied by recommended lifestyle changes.
Many experts contend that, given the high risk of relapse, the treatment is often ongoing.
This view is supported by pharmaceutical companies, who note that the results "underscore the chronic character of obesity," similar to managing conditions like high blood pressure.
User Experiences
People who have discontinued the jabs report a intense return of hunger.
"I experienced a switch flipping and you become extremely hungry," described an individual.
The struggle is compounded if patients have not adopted lasting lifestyle or habit changes during therapy.
Significant Use
Figures suggest that a significant number of people in the UK have tried weight-loss jabs in the last 12 months, with demand remaining high.
- Use is higher among women compared to males.
- The middle-aged age group shows the highest usage rates.
- A large proportion obtain the medications through private healthcare rather than the NHS.
In conclusion, clinicians emphasize that while these medications are potent agents for shedding pounds, they are not a magic cure and maintained weight loss hinges on ongoing lifestyle management.
