Fresh analysis indicates that patients who come off new GLP-1 drugs like Wegovy and Mounjaro can put back on reduced body mass much more quickly than those who stop traditional lifestyle regimens.
Research printed in a leading medical journal demonstrates that while obese people often shed a large proportion of their body weight while using the jabs, the weight returns at an average rate of 0.8 kg per month after stopping.
"Individuals buying these medications should be cognizant of the danger of rapid rebound weight gain when the therapy concludes," stated expert Dr. Susan Jebb.
That rate of regain implies a return to original mass in about a year and a half.
Comparing Approaches
The research, which reviewed 37 of trials involving over 9,000 of participants, contrasted the results of the injectable medications with other pills.
Researchers note that people who lose weight through diet and exercise typically experience a slower creep back—approximately 100 grams monthly—after stopping.
Understanding the Rapid Rebound
Experts suggest the way of the drugs explains the heightened rebound.
GLP-1 drugs mimic a body's own chemical called glucagon-like peptide-1, which moderates feelings of fullness.
"Artificially providing the hormone levels far above than the body's typical production may cause the system to produce less of its endogenous GLP-1, and may also lessen responsiveness to its effects," said Dr. Adam Collins, a dietetics researcher.
"Stopping of this medication results in hunger is no longer kept in check, making binge eating much more probable."
A Chronic Condition?
Health authorities recommend the jabs for individuals with weight-linked medical conditions, alongside prescribed diet and exercise modifications.
Professionals say that, due to the likelihood of relapse, the therapy should be considered long-term.
This view is supported by drug manufacturers, who note that the results "underscore the chronic nature of obesity," similar to managing diseases like hypertension.
User Experiences
Individuals who have stopped the medication explain a sudden return of hunger.
"It felt as if something flipping and you're instantly extremely hungry," described an individual.
This difficulty is compounded if users have not developed lasting dietary or behavioural modifications during treatment.
Growing Interest
Survey data show that millions of people in the UK have used these injections in the past year, with demand remaining high.
- Adoption is higher among females than males.
- The middle-aged age group shows the greatest level of interest.
- A large proportion access the medications through private prescriptions rather than public health services.
In conclusion, experts caution that while the jabs are powerful agents for shedding pounds, they are not a permanent solution and lasting health benefits relies on integrated lifestyle changes.
