New research indicates that individuals who stop using blockbuster GLP-1 drugs like Wegovy and Mounjaro can put back on reduced body mass far faster than those who end traditional lifestyle programs.
Findings released in a prominent medical journal demonstrates that while obese people frequently drop substantial amounts of their total mass while using the jabs, the mass returns at an average rate of 0.8 kg per month after stopping.
"Individuals purchasing such drugs need to be informed of the danger of rapid rebound weight gain when the treatment is stopped," stated lead investigator Dr. Susan Jebb.
This pace of recovery implies a return to original mass in about one and a half years.
Comparing Therapies
The study, which examined 37 of trials involving over 9,000 of participants, compared the outcomes of the injectable medications with conventional dieting.
Scientists emphasize that people who shed pounds through dieting usually have a slower creep back—perhaps 100 grams monthly—after stopping.
Understanding the Quick Regain
Nutrition scientists believe the mechanism of the injections accounts for the amplified rebound.
These medications copy a natural hormone called GLP-1, which controls feelings of fullness.
"Sustained high doses of the hormone levels far above than normal might result in the system to produce less of its endogenous GLP-1, and may also reduce sensitivity to its effects," said Dr. Adam Collins, a dietetics expert.
"Stopping of this hormone supplement results in appetite is no longer kept in check, making overeating much more probable."
A Lifelong Disease?
Health authorities suggest the jabs for individuals with obesity-related health risks, alongside recommended lifestyle changes.
A number of clinicians argue that, due to the high risk of relapse, the treatment should be considered life-long.
This perspective is reinforced by pharmaceutical companies, who say that the findings "highlight the chronic nature of excess weight," akin to managing diseases like high blood pressure.
Patient Testimonies
People who have stopped the medication report a sudden resurgence of appetite.
"It was like a switch that goes on and you're instantly starving," said one woman.
This difficulty is exacerbated if patients have not adopted sustainable lifestyle or habit changes during treatment.
Significant Interest
Recent estimates suggest that a significant number of people in the UK have used these injections in the past year, with desire being substantial.
- Use is greater among females than males.
- The 40s and 50s demographic shows the greatest usage rates.
- A large proportion access the drugs through private healthcare rather than the NHS.
Ultimately, researchers emphasize that while the jabs are effective tools for shedding pounds, they are not a magic solution and lasting health benefits hinges on integrated behavioural changes.
