Fresh analysis suggests that individuals who stop using blockbuster slimming jabs like Mounjaro or Wegovy may regain lost weight at a significantly accelerated pace than those who stop conventional lifestyle plans.
Research printed in a leading medical journal shows that while overweight people often shed substantial amounts of their total mass while undergoing treatment, the weight comes back at an average rate of 0.8 kg per month once they quit.
"Users buying these treatments must be aware of the danger of quick rebound weight gain when the medication is stopped," cautioned expert Dr. Susan Jebb.
That rate of recovery suggests a return to original mass within about a year and a half.
Analyzing Approaches
The study, which examined dozens of studies involving over 9,000 of patients, compared the effects of the injectable medications with older methods.
Scientists point out that individuals who lose weight through lifestyle changes alone generally have a slower weight regain—around 0.1 kg a month—once they finish.
Explaining the Rapid Regain
Experts propose the mechanism of the injections accounts for the heightened rebound.
GLP-1 drugs imitate a body's own chemical called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Artificially providing GLP-1 levels far above than the body's typical production could lead to the system to produce less of its own natural GLP-1, and may also lessen sensitivity to its effects," said Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this medication results in appetite is uncontrolled, making overeating far more likely."
A Chronic Disease?
The NHS recommend the jabs for individuals with weight-linked health risks, accompanied by prescribed lifestyle changes.
Professionals argue that, considering the significant potential of weight regain, the therapy is often long-term.
This perspective is echoed by drug manufacturers, who say that the findings "underscore the chronic character of obesity," comparing it to managing conditions like diabetes.
User Accounts
Individuals who have stopped the jabs describe a intense return of appetite.
"I experienced a switch that goes on and you become extremely hungry," described a patient.
This challenge is compounded if users have not adopted sustainable lifestyle or habit changes during treatment.
Significant Use
Survey data suggest that millions of people in the UK have used these injections in the past year, with demand being substantial.
- Adoption is greater among females than men.
- The middle-aged age group shows the highest usage rates.
- Many obtain the drugs through private healthcare rather than public health services.
In conclusion, researchers caution that while the jabs are powerful agents for shedding pounds, they are not a magic fix and lasting health benefits relies on integrated lifestyle changes.
