New research indicates that people who discontinue popular GLP-1 drugs like Mounjaro or Wegovy may regain reduced body mass much more quickly than those who halt conventional diet and exercise plans.
Published data in a prominent health publication points out that while overweight individuals can lose a large proportion of their total mass while using the jabs, the mass comes back at an estimated rate of 0.8 kg per month after stopping.
"Users buying these medications need to be cognizant of the danger of fast rebound weight gain when the treatment concludes," warns lead investigator Dr. Susan Jebb.
That rate of regain implies a return to pre-treatment mass within about 18 months.
Analyzing Therapies
The study, which examined dozens of studies involving over 9,000 of participants, contrasted the results of these new drugs with conventional dieting.
Scientists emphasize that individuals who shed pounds through diet and exercise usually see a slower creep back—perhaps 100 grams monthly—once they finish.
The Reason for the Quick Rebound
Doctors believe the way of the drugs is key to understanding the heightened weight return.
GLP-1 drugs imitate a body's own chemical called glucagon-like peptide-1, which helps regulate hunger.
"Sustained high doses of GLP-1 levels far above than the body's typical production could lead to the body to generate a reduced amount of its own natural hormone, and may also diminish sensitivity to its effects," noted Dr. Adam Collins, a dietetics expert.
"Stopping of this medication leads to appetite is no longer kept in check, making overeating much more probable."
A Lifelong Condition?
The NHS advise the injections for individuals with weight-linked health risks, accompanied by recommended diet and exercise modifications.
Many experts argue that, due to the high risk of relapse, the therapy should be considered life-long.
This opinion is echoed by drug manufacturers, who state that the findings "emphasize the persistent character of obesity," similar to managing diseases like hypertension.
Patient Experiences
Individuals who have stopped the jabs describe a powerful resurgence of hunger.
"I experienced something that goes on and you become starving," recalled a patient.
The struggle is worsened if individuals have not established permanent dietary or behavioural modifications during treatment.
Widespread Use
Survey data indicate that a significant number of people in the UK have used these injections in the last 12 months, with demand remaining high.
- Adoption is higher among females compared to males.
- The 40s and 50s demographic shows the highest usage rates.
- Many access the medications through private healthcare rather than public health services.
Finally, researchers caution that while the jabs are effective agents for weight loss, they are not a magic solution and lasting health benefits hinges on ongoing lifestyle support.
