Fresh analysis indicates that individuals who come off new slimming jabs like Mounjaro or Wegovy may regain lost weight far faster than those who end traditional lifestyle programs.
Research printed in a major medical journal demonstrates that while obese individuals often shed about a fifth of their body weight while using the jabs, the weight returns at an estimated rate of 0.8 kg per month after stopping.
"Individuals buying these treatments need to be aware of the danger of rapid weight regain when the therapy concludes," cautioned researcher Dr. Susan Jebb.
Such speed of regain implies a return to pre-treatment mass in about one and a half years.
Weighing Approaches
The analysis, which looked at dozens of trials involving thousands of patients, compared the effects of the injectable medications with older methods.
Researchers emphasize that individuals who shed pounds through lifestyle changes alone generally have a slower weight regain—approximately 100 grams monthly—post-intervention.
Understanding the Fast Rebound
Doctors propose the way of the jabs accounts for the accelerated weight return.
The injections imitate 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 could lead to the system to produce less of its endogenous hormone, and could lessen responsiveness to its actions," said Dr. Adam Collins, a nutrition expert.
"Discontinuation of this hormone supplement results in hunger is uncontrolled, making overeating much more probable."
A Chronic Issue?
Medical guidelines advise the jabs for people with obesity-related medical conditions, accompanied by prescribed diet and exercise modifications.
Professionals say that, due to the significant potential of relapse, the treatment is often long-term.
This view is supported by drug manufacturers, who note that the findings "underscore the long-term character of obesity," comparing it to managing conditions like diabetes.
User Testimonies
People who have discontinued the jabs report a powerful resurgence of hunger.
"It was like a trigger flipping and you're instantly starving," recalled a patient.
This difficulty is compounded if users have not developed permanent dietary or behavioural changes during therapy.
Widespread Adoption
Survey data show that a significant number of people in the UK have used these injections in the last 12 months, with interest remaining high.
- Adoption is greater among women compared to males.
- The middle-aged demographic shows the highest usage rates.
- A large proportion obtain the medications through private prescriptions rather than the NHS.
Finally, experts caution that while the jabs are potent tools for shedding pounds, they are not a permanent cure and lasting health benefits relies on integrated lifestyle support.
