Fresh analysis suggests that people who come off blockbuster slimming jabs like Wegovy and Mounjaro tend to recover shed pounds far faster than those who halt traditional diet and exercise programs.
Research printed in a prominent health publication shows that while obese individuals can lose about a fifth of their body weight while on the medication, the mass returns at an average rate of 0.8 kg per month once they quit.
"Individuals purchasing such treatments should be informed of the risk of rapid weight regain when the medication is stopped," stated lead investigator Dr. Susan Jebb.
That rate of recovery means a reversion to original mass in about 18 months.
Weighing Treatments
The study, which reviewed 37 of trials involving thousands of patients, compared the outcomes of GLP-1 agonists with older methods.
Scientists emphasize that people who shed pounds through lifestyle changes alone generally have a more gradual creep back—approximately 100 grams monthly—post-intervention.
Understanding the Quick Rebound
Experts propose the way of the jabs is key to understanding the accelerated weight return.
GLP-1 drugs mimic a body's own chemical called glucagon-like peptide-1, which helps regulate appetite.
"Sustained high doses of the hormone concentrations several times higher than the body's typical production could lead to the body to produce less of its endogenous GLP-1, and may also diminish responsiveness to its actions," said Dr. Adam Collins, a dietetics researcher.
"Stopping of this medication means appetite is uncontrolled, making excessive eating far more likely."
An Ongoing Disease?
The NHS recommend the jabs for individuals with weight-linked medical conditions, alongside prescribed diet and exercise modifications.
Many experts say that, given the significant potential of relapse, the therapy is often life-long.
This view is reinforced by drug manufacturers, who say that the findings "emphasize the chronic character of obesity," akin to managing conditions like diabetes.
User Testimonies
People who have stopped the jabs report a intense resurgence of hunger.
"It was like something activating and you become extremely hungry," said one woman.
This difficulty is exacerbated if individuals have not established permanent lifestyle or habit changes during treatment.
Significant Adoption
Figures suggest that millions of people in the UK have tried weight-loss jabs in the last 12 months, with desire being substantial.
- Use is greater among women compared to males.
- The 40s and 50s age group shows the greatest level of interest.
- Many access the medications through private prescriptions rather than public health services.
Finally, researchers emphasize that while GLP-1 drugs are potent tools for weight loss, they are not a standalone cure and long-term success likely depends on combined lifestyle support.
