A recent study reveals that people who stop using blockbuster GLP-1 drugs like Mounjaro or Wegovy can put back on reduced body mass far faster than those who end conventional lifestyle plans.
Findings released in a major medical journal demonstrates that while obese individuals often shed about a fifth of their body weight while undergoing treatment, the weight is regained at an estimated rate of nearly a kilo each month once they quit.
"Users buying these medications should be cognizant of the danger of fast rebound weight gain when the medication is stopped," stated researcher Dr. Susan Jebb.
This pace of recovery implies a return to original mass in about a year and a half.
Comparing Approaches
The research, which examined dozens of trials involving thousands of participants, contrasted the outcomes of these new drugs with other pills.
Scientists point out that people who shed pounds through lifestyle changes alone usually experience a more gradual weight regain—perhaps 0.1 kg a month—once they finish.
The Reason for the Rapid Rebound
Doctors believe the way of the injections explains the heightened rebound.
The injections mimic a natural hormone called GLP-1, which moderates appetite.
"Long-term administration of the hormone levels far above than normal may cause the system to produce less of its own natural GLP-1, and could lessen sensitivity to its actions," noted Dr. Adam Collins, a dietetics expert.
"Stopping of this GLP-1 'fix' leads to appetite is uncontrolled, making excessive eating much more probable."
A Chronic Disease?
Health authorities advise the injections for people with weight-linked health risks, accompanied by recommended lifestyle changes.
A number of clinicians contend that, due to the high risk of weight regain, the therapy is often life-long.
This perspective is supported by drug manufacturers, who state that the results "emphasize the persistent nature of obesity," akin to managing diseases like hypertension.
Patient Accounts
Users who have come off the jabs describe a intense return of cravings.
"It felt as if a trigger flipping and I was suddenly ravenous," recalled a patient.
The struggle is worsened if patients have not adopted permanent lifestyle or habit changes during treatment.
Widespread Adoption
Figures show that millions of adults in the UK have used these injections in the past year, with desire remaining high.
- Use is more common among women than males.
- The middle-aged age group shows the highest level of interest.
- A large proportion access the medications through private healthcare rather than public health services.
Ultimately, experts stress that while these medications are powerful agents for shedding pounds, they are not a standalone solution and maintained weight loss hinges on integrated lifestyle support.
