Fresh analysis reveals that patients who come off new slimming jabs like Mounjaro or Wegovy tend to recover reduced body mass at a significantly accelerated pace than those who halt conventional lifestyle regimens.
Published data in a major medical journal points out that while overweight people frequently drop substantial amounts of their total mass while using the jabs, the mass returns at an average rate of nearly a kilo each month once they quit.
"People using these drugs need to be cognizant of the potential of fast rebound weight gain when the therapy is stopped," stated expert Dr. Susan Jebb.
This pace of recovery means a reversion to original weight within about 18 months.
Weighing Treatments
The analysis, which examined 37 of trials involving thousands of patients, contrasted the effects of these new drugs with other pills.
The team note that people who lose weight through diet and exercise typically experience a more gradual weight regain—perhaps 100 grams monthly—after stopping.
Explaining the Quick Regain
Doctors believe the mode of action of the injections is key to understanding the heightened rebound.
These medications imitate a natural hormone called GLP-1, which helps regulate appetite.
"Long-term administration of GLP-1 levels several times higher than normal could lead to the system to generate a reduced amount of its own natural GLP-1, and could reduce sensitivity to its actions," said Dr. Adam Collins, a nutrition expert.
"Withdrawal of this hormone supplement means appetite is no longer kept in check, making overeating far more likely."
An Ongoing Disease?
The NHS suggest the jabs for individuals with obesity-related health risks, accompanied by prescribed lifestyle changes.
Professionals argue that, given the high risk of relapse, the therapy should be considered ongoing.
This perspective is reinforced by drug manufacturers, who say that the results "emphasize the chronic character of obesity," similar to managing diseases like diabetes.
User Experiences
People who have come off the jabs explain a powerful return of cravings.
"It felt as if a trigger that goes on and I was suddenly extremely hungry," said an individual.
This challenge is compounded if patients have not adopted sustainable lifestyle or habit changes during therapy.
Growing Use
Recent estimates indicate that a significant number of adults in the UK have tried these injections in the last 12 months, with demand continuing to grow.
- Adoption is higher among females than males.
- The 40s and 50s demographic shows the highest usage rates.
- Many obtain the drugs through private prescriptions rather than public health services.
Ultimately, researchers stress that while GLP-1 drugs are potent tools for shedding pounds, they are not a permanent solution and maintained weight loss relies on combined lifestyle changes.
