Fresh analysis indicates that patients who discontinue new slimming jabs like Wegovy and Mounjaro tend to recover shed pounds far faster than those who stop traditional diet and exercise programs.
Research printed in a prominent medical journal points out that while overweight people can lose a large proportion of their body weight while on the medication, the mass comes back at an average rate of nearly a kilo each month once they quit.
"Users buying these medications must be cognizant of the risk of quick rebound weight gain when the treatment concludes," warns expert Dr. Susan Jebb.
This pace of recovery suggests a return to starting weight within about a year and a half.
Weighing Therapies
The analysis, which examined dozens of trials involving over 9,000 of patients, contrasted the outcomes of the injectable medications with conventional dieting.
The team point out that individuals who lose weight through lifestyle changes alone generally have a less rapid weight regain—approximately 100 grams monthly—after stopping.
The Reason for the Quick Regain
Nutrition scientists suggest the mode of action of the drugs explains the accelerated weight return.
The injections imitate a body's own chemical called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Sustained high doses of the hormone concentrations several times higher than the body's typical production might result in the body to produce less of its endogenous GLP-1, and could lessen responsiveness to its actions," explained Dr. Adam Collins, a dietetics specialist.
"Discontinuation of this medication means hunger is unsuppressed, making overeating much more probable."
An Ongoing Disease?
Medical guidelines suggest the injections for people with weight-linked health risks, alongside recommended lifestyle changes.
Many experts contend that, due to the high risk of weight regain, the treatment should be considered long-term.
This opinion is echoed by pharmaceutical companies, who note that the findings "underscore the persistent nature of obesity," similar to managing conditions like hypertension.
User Accounts
Individuals who have stopped the medication describe a intense return of appetite.
"I experienced a switch that goes on and I was suddenly extremely hungry," recalled a patient.
This difficulty is exacerbated if users have not developed sustainable dietary or behavioural changes during treatment.
Growing Interest
Recent estimates show that millions of people in the UK have tried weight-loss jabs in the last 12 months, with desire remaining high.
- Adoption is higher among females compared to males.
- The 40s and 50s demographic shows the greatest usage rates.
- Many access the medications through private prescriptions rather than the NHS.
Finally, experts emphasize that while these medications are effective agents for shedding pounds, they are not a standalone fix and maintained weight loss likely depends on combined lifestyle support.
