New research suggests that patients who stop using popular weight-loss injections like Wegovy and Mounjaro tend to recover lost weight much more quickly than those who stop traditional diet and exercise regimens.
Findings released in a major medical journal demonstrates that while overweight people often shed substantial amounts of their total mass while on the medication, the weight returns at an average rate of nearly a kilo each month once they quit.
"Users buying such medications must be cognizant of the danger of quick rebound weight gain when the treatment concludes," cautioned lead investigator Dr. Susan Jebb.
That rate of regain means a return to starting mass within about a year and a half.
Comparing Therapies
The research, which examined dozens of trials involving thousands of patients, compared the results of these new drugs with other pills.
Researchers emphasize that people who shed pounds through lifestyle changes alone generally see a slower weight regain—perhaps 100 grams monthly—once they finish.
Explaining the Fast Rebound
Nutrition scientists believe the mode of action of the jabs explains the amplified regain.
The injections copy a natural hormone called GLP-1, which moderates appetite.
"Sustained high doses of the hormone concentrations far above than normal might result in the body to generate a reduced amount of its own natural hormone, and may also diminish responsiveness to its actions," noted Dr. Adam Collins, a dietetics researcher.
"Withdrawal of this GLP-1 'fix' results in appetite is no longer kept in check, making binge eating much more probable."
An Ongoing Issue?
Medical guidelines advise the jabs for individuals with weight-linked medical conditions, alongside prescribed lifestyle changes.
Professionals say that, considering the high risk of relapse, the therapy is often long-term.
This perspective is reinforced by drug manufacturers, who state that the findings "highlight the chronic character of obesity," similar to managing diseases like hypertension.
Patient Experiences
People who have come off the medication report a intense resurgence of cravings.
"I experienced a switch that goes on and you're instantly starving," said a patient.
The struggle is worsened if users have not developed lasting lifestyle or habit changes during treatment.
Significant Interest
Recent estimates suggest that a significant number of adults in the UK have used weight-loss jabs in the past year, with desire remaining high.
- Adoption is more common among women than men.
- The middle-aged demographic shows the greatest level of interest.
- A large proportion obtain the medications through private prescriptions rather than public health services.
Finally, experts emphasize that while GLP-1 drugs are effective agents for shedding pounds, they are not a permanent fix and maintained weight loss relies on ongoing lifestyle changes.
