A recent study indicates that individuals who stop using new GLP-1 drugs like Mounjaro or Wegovy may regain reduced body mass at a significantly accelerated pace than those who end traditional diet and exercise regimens.
Published data in a leading health publication shows that while obese people often shed a large proportion of their body weight while using the jabs, the weight comes back at an average rate of nearly a kilo each month after stopping.
"People using these medications must be aware of the danger of quick weight regain when the therapy is stopped," stated researcher Dr. Susan Jebb.
That rate of regain implies a return to starting mass within about a year and a half.
Weighing Treatments
The study, which examined dozens of studies involving over 9,000 of patients, contrasted the effects of GLP-1 agonists with other pills.
Researchers point out that people who shed pounds through dieting typically have a more gradual creep back—perhaps 100 grams monthly—once they finish.
The Reason for the Quick Regain
Nutrition scientists propose the mode of action of the jabs accounts for the accelerated weight return.
These medications copy a natural hormone called GLP-1, which controls feelings of fullness.
"Artificially providing the hormone levels several times higher than normal might result in the system to generate a reduced amount of its endogenous GLP-1, and may also reduce responsiveness to its actions," noted Dr. Adam Collins, a dietetics researcher.
"Stopping of this GLP-1 'fix' means appetite is no longer kept in check, making binge eating much more probable."
A Chronic Condition?
The NHS recommend the injections for individuals with weight-linked health risks, alongside recommended lifestyle changes.
Many experts contend that, given the significant potential of weight regain, the therapy is often ongoing.
This view is reinforced by pharmaceutical companies, who state that the results "emphasize the chronic nature of excess weight," akin to managing diseases like diabetes.
User Testimonies
Individuals who have come off the medication describe a powerful resurgence of hunger.
"I experienced something flipping and you become starving," said one woman.
This challenge is compounded if patients have not developed permanent dietary or behavioural changes during therapy.
Growing Use
Survey data indicate that millions of people in the UK have used weight-loss jabs in the past year, with demand being substantial.
- Use is more common among women compared to men.
- The 40s and 50s age group shows the greatest level of interest.
- Many obtain the medications through private prescriptions rather than public health services.
Finally, clinicians stress that while the jabs are effective agents for weight loss, they are not a magic solution and long-term success likely depends on integrated behavioural changes.
