New research suggests that patients who come off blockbuster weight-loss injections like Wegovy and Mounjaro tend to recover shed pounds far faster than those who stop traditional diet and exercise regimens.
Research printed in a leading medical journal shows that while overweight people frequently drop about a fifth of their total mass while using the jabs, the mass returns at an estimated rate of 0.8 kg per month upon discontinuation.
"Users buying such medications should be cognizant of the risk of quick weight regain when the medication is stopped," warns researcher Dr. Susan Jebb.
That rate of recovery means a return to starting mass in about a year and a half.
Weighing Treatments
The analysis, which examined dozens of trials involving thousands of patients, contrasted the outcomes of GLP-1 agonists with older methods.
Researchers emphasize that people who shed pounds through dieting usually see a slower weight regain—perhaps 0.1 kg a month—post-intervention.
Understanding the Quick Regain
Experts believe the mechanism of the drugs explains the amplified rebound.
The injections copy a natural hormone called glucagon-like peptide-1, which helps regulate appetite.
"Long-term administration of GLP-1 concentrations several times higher than the body's typical production might result in the system to generate a reduced amount of its endogenous hormone, and may also diminish sensitivity to its actions," noted Dr. Adam Collins, a dietetics specialist.
"Stopping of this hormone supplement results in appetite is unsuppressed, making binge eating much more probable."
A Lifelong Issue?
Health authorities suggest the injections for individuals with weight-linked medical conditions, alongside recommended diet and exercise modifications.
Professionals say that, considering the high risk of weight regain, the treatment should be considered ongoing.
This view is supported by pharmaceutical companies, who state that the findings "highlight the persistent character of obesity," comparing it to managing diseases like hypertension.
Patient Testimonies
People who have stopped the jabs report a intense resurgence of cravings.
"I experienced a switch activating and I was suddenly extremely hungry," recalled an individual.
This difficulty is compounded if individuals have not adopted lasting dietary or behavioural modifications during therapy.
Significant Interest
Figures suggest that millions of adults in the UK have used weight-loss jabs in the last 12 months, with desire being substantial.
- Adoption is more common among women compared to men.
- The 40s and 50s age group shows the greatest usage rates.
- A large proportion obtain the drugs through private prescriptions rather than the NHS.
Finally, clinicians caution that while the jabs are effective agents for weight loss, they are not a standalone cure and maintained weight loss hinges on integrated lifestyle management.
