New research reveals that patients who come off blockbuster GLP-1 drugs like Mounjaro or Wegovy may regain reduced body mass much more quickly than those who halt conventional diet and exercise regimens.
Findings released in a leading medical journal shows that while obese individuals often shed a large proportion of their total mass while using the jabs, the mass comes back at an estimated rate of nearly a kilo each month once they quit.
"Users purchasing these treatments must be cognizant of the potential of rapid weight regain when the treatment concludes," warns expert Dr. Susan Jebb.
That rate of regain suggests a return to starting mass within about a year and a half.
Weighing Therapies
The study, which reviewed dozens of trials involving thousands of patients, contrasted the effects of these new drugs with older methods.
Researchers note that individuals who shed pounds through diet and exercise usually experience a slower weight regain—approximately 0.1 kg a month—after stopping.
Explaining the Rapid Rebound
Experts believe the way of the drugs accounts for the amplified rebound.
These medications copy a natural hormone called glucagon-like peptide-1, which moderates feelings of fullness.
"Artificially providing the hormone levels far above than normal may cause the system to generate a reduced amount of its endogenous GLP-1, and could reduce responsiveness to its actions," noted Dr. Adam Collins, a dietetics researcher.
"Withdrawal of this GLP-1 'fix' means appetite is unsuppressed, making binge eating a significant risk."
An Ongoing Disease?
Health authorities advise the injections for individuals with weight-linked medical conditions, accompanied by recommended diet and exercise modifications.
Professionals argue that, considering the high risk of relapse, the treatment should be considered ongoing.
This opinion is echoed by drug manufacturers, who state that the findings "highlight the chronic character of obesity," comparing it to managing diseases like hypertension.
User Testimonies
Users who have come off the jabs report a intense resurgence of cravings.
"It felt as if a trigger activating and I was suddenly ravenous," said an individual.
The struggle is compounded if individuals have not established sustainable lifestyle or habit changes during treatment.
Widespread Interest
Survey data show that a significant number of adults in the UK have used weight-loss jabs in the past year, with desire continuing to grow.
- Adoption is higher among females compared to men.
- The middle-aged demographic shows the greatest usage rates.
- Many obtain the medications through private prescriptions rather than public health services.
Ultimately, clinicians caution that while these medications are powerful tools for weight loss, they are not a permanent fix and maintained weight loss likely depends on integrated lifestyle support.
