A recent study reveals that people who come off popular slimming jabs like Wegovy and Mounjaro can put back on reduced body mass far faster than those who stop conventional lifestyle plans.
Published data in a leading health publication demonstrates that while overweight people can lose a large proportion of their total mass while undergoing treatment, the mass is regained at an estimated rate of 0.8 kg per month upon discontinuation.
"Users purchasing these medications need to be aware of the potential of fast rebound weight gain when the treatment ends," cautioned expert Dr. Susan Jebb.
That rate of recovery suggests a reversion to original weight within about a year and a half.
Comparing Approaches
The analysis, which examined 37 of studies involving thousands of participants, contrasted the outcomes of GLP-1 agonists with other pills.
Researchers point out that individuals who shed pounds through diet and exercise generally experience a more gradual creep back—around 0.1 kg a month—after stopping.
The Reason for the Quick Rebound
Nutrition scientists believe the mechanism of the jabs accounts for the amplified weight return.
These medications imitate a natural hormone called glucagon-like peptide-1, which helps regulate appetite.
"Artificially providing GLP-1 concentrations several times higher than the body's typical production could lead to the system to produce less of its endogenous GLP-1, and could diminish responsiveness to its effects," explained Dr. Adam Collins, a nutrition expert.
"Withdrawal of this medication leads to hunger is no longer kept in check, making overeating much more probable."
An Ongoing Condition?
The NHS recommend the jabs for individuals with weight-linked health risks, alongside prescribed diet and exercise modifications.
Many experts argue that, considering the likelihood of relapse, the therapy might need to be long-term.
This opinion is reinforced by pharmaceutical companies, who note that the findings "highlight the chronic character of obesity," similar to managing conditions like diabetes.
User Testimonies
Users who have discontinued the jabs describe a powerful return of appetite.
"It was like a trigger flipping and you become extremely hungry," recalled one woman.
The struggle is compounded if patients have not developed permanent dietary or behavioural changes during therapy.
Significant Adoption
Recent estimates show that a significant number of adults in the UK have tried weight-loss jabs in the past year, with interest remaining high.
- Use is more common among females than men.
- The middle-aged age group shows the highest level of interest.
- A large proportion obtain the drugs through private prescriptions rather than public health services.
Finally, experts emphasize that while these medications are potent agents for weight loss, they are not a standalone cure and long-term success hinges on ongoing lifestyle management.
