A recent study indicates that individuals who discontinue blockbuster slimming jabs like Wegovy and Mounjaro may regain shed pounds at a significantly accelerated pace than those who stop traditional diet and exercise programs.
Research printed in a major health publication points out that while overweight individuals can lose about a fifth of their total mass while on the medication, the mass returns at an average rate of nearly a kilo each month once they quit.
"Individuals buying such drugs need to be cognizant of the danger of fast rebound weight gain when the medication ends," warns lead investigator Dr. Susan Jebb.
Such speed of recovery means a reversion to pre-treatment mass in about one and a half years.
Weighing Therapies
The research, which reviewed dozens of trials involving thousands of patients, contrasted the effects of GLP-1 agonists with conventional dieting.
Researchers point out that individuals who shed pounds through lifestyle changes alone generally have a more gradual weight regain—approximately 100 grams monthly—once they finish.
Understanding the Fast Regain
Nutrition scientists suggest the mode of action of the injections explains the heightened rebound.
The injections imitate a body's own chemical called glucagon-like peptide-1, which moderates hunger.
"Long-term administration of GLP-1 concentrations far above than the body's typical production might result in the system to generate a reduced amount of its endogenous hormone, and could reduce responsiveness to its actions," explained Dr. Adam Collins, a dietetics expert.
"Withdrawal of this GLP-1 'fix' means hunger is unsuppressed, making excessive eating a significant risk."
A Lifelong Issue?
Health authorities recommend the jabs for individuals with obesity-related medical conditions, accompanied by prescribed lifestyle changes.
Many experts say that, considering the significant potential of weight regain, the treatment should be considered long-term.
This opinion is reinforced by drug manufacturers, who note that the findings "highlight the chronic nature of obesity," comparing it to managing diseases like hypertension.
Patient Testimonies
People who have stopped the jabs report a intense return of cravings.
"I experienced a switch activating and you become extremely hungry," said a patient.
The struggle is exacerbated if patients have not established lasting lifestyle or habit changes during therapy.
Growing Interest
Figures indicate that a significant number of adults in the UK have tried these injections in the last 12 months, with desire being substantial.
- Use is higher among females compared to males.
- The 40s and 50s demographic shows the highest usage rates.
- A large proportion obtain the drugs through private healthcare rather than public health services.
Ultimately, clinicians emphasize that while these medications are potent tools for shedding pounds, they are not a permanent solution and lasting health benefits hinges on combined behavioural management.
