Fresh analysis suggests that people who come off new weight-loss injections like Wegovy and Mounjaro may regain reduced body mass at a significantly accelerated pace than those who halt conventional diet and exercise plans.
Published data in a major health publication points out that while overweight individuals frequently drop a large proportion of their body weight while using the jabs, the weight comes back at an estimated rate of nearly a kilo each month after stopping.
"People purchasing these medications must be informed of the danger of fast rebound weight gain when the treatment is stopped," warns researcher Dr. Susan Jebb.
That rate of recovery suggests a return to starting weight within about one and a half years.
Comparing Therapies
The study, which examined 37 of trials involving over 9,000 of patients, compared the outcomes of GLP-1 agonists with other pills.
The team emphasize that individuals who shed pounds through dieting usually see a slower creep back—perhaps 100 grams monthly—once they finish.
Understanding the Quick Regain
Experts propose the mechanism of the injections explains the accelerated regain.
GLP-1 drugs mimic a natural hormone called GLP-1, which helps regulate feelings of fullness.
"Sustained high doses of the hormone concentrations several times higher than normal may cause the system to generate a reduced amount of its endogenous hormone, and may also lessen responsiveness to its actions," noted Dr. Adam Collins, a dietetics researcher.
"Discontinuation of this GLP-1 'fix' leads to hunger is uncontrolled, making overeating far more likely."
A Chronic Disease?
Health authorities recommend the injections for individuals with weight-linked health risks, accompanied by prescribed diet and exercise modifications.
Professionals say that, considering the high risk of relapse, the therapy should be considered ongoing.
This opinion is reinforced by pharmaceutical companies, who state that the findings "highlight the long-term nature of obesity," similar to managing diseases like high blood pressure.
User Accounts
Individuals who have discontinued the medication describe a sudden resurgence of cravings.
"It was like a switch activating and you're instantly ravenous," said a patient.
This challenge is worsened if users have not adopted permanent lifestyle or habit changes during treatment.
Growing Interest
Recent estimates show that a significant number of people in the UK have used weight-loss jabs in the past year, with interest continuing to grow.
- Adoption is more common among females compared to males.
- The middle-aged demographic shows the greatest level of interest.
- Many access the drugs through private healthcare rather than public health services.
Ultimately, clinicians caution that while the jabs are powerful tools for shedding pounds, they are not a standalone solution and maintained weight loss hinges on integrated lifestyle support.
