New research indicates that people who discontinue blockbuster slimming jabs like Wegovy and Mounjaro can put back on lost weight at a significantly accelerated pace than those who stop traditional diet and exercise programs.
Findings released in a major medical journal demonstrates that while overweight individuals can lose a large proportion of their body weight while undergoing treatment, the mass is regained at an average rate of nearly a kilo each month after stopping.
"Individuals purchasing such medications should be aware of the potential of fast rebound weight gain when the treatment is stopped," warns expert Dr. Susan Jebb.
This pace of regain suggests a return to original mass in about a year and a half.
Analyzing Approaches
The analysis, which reviewed 37 of studies involving thousands of participants, contrasted the outcomes of GLP-1 agonists with other pills.
Researchers point out that individuals who lose weight through dieting typically experience a slower creep back—approximately 100 grams monthly—once they finish.
Explaining the Fast Rebound
Doctors propose the way of the injections explains the accelerated weight return.
The injections mimic a natural hormone called GLP-1, which helps regulate appetite.
"Sustained high doses of the hormone levels several times higher than normal could lead to the body to generate a reduced amount of its endogenous hormone, and may also reduce responsiveness to its actions," explained Dr. Adam Collins, a nutrition expert.
"Stopping of this hormone supplement results in appetite is uncontrolled, making binge eating much more probable."
A Chronic Issue?
Health authorities advise the jabs for people with weight-linked health risks, alongside prescribed diet and exercise modifications.
Professionals say that, due to the high risk of weight regain, the therapy is often long-term.
This view is reinforced by drug manufacturers, who note that the results "emphasize the long-term character of obesity," akin to managing diseases like diabetes.
Patient Accounts
Individuals who have discontinued the medication explain a intense resurgence of appetite.
"It was like something activating and I was suddenly extremely hungry," described a patient.
The struggle is compounded if users have not adopted sustainable lifestyle or habit changes during treatment.
Significant Use
Figures indicate that a significant number of adults in the UK have used weight-loss jabs in the last 12 months, with desire continuing to grow.
- Use is higher among women compared to men.
- The 40s and 50s demographic shows the greatest usage rates.
- Many access the drugs through private prescriptions rather than public health services.
Finally, clinicians emphasize that while the jabs are effective tools for shedding pounds, they are not a standalone cure and long-term success hinges on integrated lifestyle support.
