Fresh analysis reveals that people who discontinue new slimming jabs like Wegovy and Mounjaro may regain shed pounds much more quickly than those who stop conventional lifestyle programs.
Research printed in a prominent medical journal shows that while obese people often shed a large proportion of their body weight while on the medication, the mass comes back at an average rate of 0.8 kg per month once they quit.
"Individuals using these medications need to be cognizant of the potential of quick rebound weight gain when the treatment is stopped," stated expert Dr. Susan Jebb.
Such speed of recovery suggests a reversion to starting mass within about one and a half years.
Weighing Treatments
The analysis, which reviewed dozens of trials involving over 9,000 of participants, contrasted the effects of GLP-1 agonists with other pills.
Researchers note that individuals who shed pounds through diet and exercise typically see a more gradual creep back—approximately 100 grams monthly—post-intervention.
The Reason for the Rapid Regain
Experts suggest the mechanism of the drugs is key to understanding the accelerated rebound.
The injections mimic a natural hormone called glucagon-like peptide-1, which moderates 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 hormone, and could reduce sensitivity to its effects," explained Dr. Adam Collins, a nutrition researcher.
"Stopping of this hormone supplement results in hunger is unsuppressed, making binge eating much more probable."
A Lifelong Disease?
Medical guidelines recommend the jabs for people with obesity-related health risks, accompanied by recommended diet and exercise modifications.
A number of clinicians say that, considering the high risk of relapse, the treatment might need to be life-long.
This opinion is echoed by pharmaceutical companies, who say that the findings "emphasize the chronic nature of excess weight," comparing it to managing diseases like diabetes.
User Experiences
Individuals who have stopped the jabs report a intense return of hunger.
"It was like a switch flipping and I was suddenly ravenous," said one woman.
This difficulty is compounded if individuals have not adopted sustainable dietary or behavioural changes during therapy.
Significant Interest
Survey data suggest that millions of people in the UK have tried weight-loss jabs in the last 12 months, with demand being substantial.
- Use is greater among women than men.
- The 40s and 50s demographic shows the highest level of interest.
- Many obtain the drugs through private healthcare rather than public health services.
In conclusion, researchers stress that while the jabs are powerful agents for shedding pounds, they are not a magic solution and long-term success likely depends on integrated lifestyle support.
