A recent study indicates that individuals who discontinue new slimming jabs like Wegovy and Mounjaro tend to recover shed pounds at a significantly accelerated pace than those who halt conventional diet and exercise regimens.
Research printed in a leading medical journal points out that while obese people often shed a large proportion of their total mass while undergoing treatment, the mass comes back at an average rate of 0.8 kg per month upon discontinuation.
"Individuals using these treatments must be aware of the danger of fast rebound weight gain when the treatment ends," cautioned expert Dr. Susan Jebb.
That rate of recovery suggests a return to pre-treatment weight in about a year and a half.
Comparing Treatments
The research, which looked at dozens of studies involving thousands of participants, contrasted the outcomes of the injectable medications with conventional dieting.
The team note that people who lose weight through dieting typically see a slower creep back—approximately 100 grams monthly—post-intervention.
Explaining the Quick Rebound
Nutrition scientists propose the way of the drugs is key to understanding the accelerated weight return.
These medications mimic a natural hormone called glucagon-like peptide-1, which helps regulate appetite.
"Long-term administration of GLP-1 concentrations several times higher than normal could lead to the body to generate a reduced amount of its endogenous GLP-1, and may also diminish sensitivity to its effects," said Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this medication leads to appetite is uncontrolled, making overeating much more probable."
A Lifelong Condition?
Health authorities recommend the injections for people with weight-linked medical conditions, alongside prescribed lifestyle changes.
Many experts argue that, considering the significant potential of relapse, the therapy should be considered ongoing.
This opinion is reinforced by pharmaceutical companies, who say that the findings "emphasize the persistent nature of excess weight," akin to managing conditions like high blood pressure.
User Testimonies
Users who have discontinued the medication report a powerful return of appetite.
"It was like a trigger flipping and I was suddenly starving," described an individual.
This difficulty is exacerbated if individuals have not developed sustainable dietary or behavioural modifications during treatment.
Significant Use
Survey data suggest that a significant number of people in the UK have tried these injections in the last 12 months, with interest being substantial.
- Adoption is greater among females than men.
- The middle-aged age group shows the highest usage rates.
- A large proportion obtain the drugs through private healthcare rather than public health services.
Finally, researchers stress that while these medications are potent agents for shedding pounds, they are not a permanent cure and maintained weight loss hinges on ongoing behavioural support.
