Fresh analysis suggests that individuals who come off blockbuster slimming jabs like Wegovy and Mounjaro tend to recover reduced body mass much more quickly than those who end traditional lifestyle regimens.
Published data in a prominent medical journal points out that while obese individuals can lose a large proportion of their total mass while on the medication, the weight comes back at an average rate of nearly a kilo each month after stopping.
"People using such treatments need to be aware of the danger of fast weight regain when the medication is stopped," cautioned lead investigator Dr. Susan Jebb.
This pace of regain implies a reversion to pre-treatment mass within about one and a half years.
Weighing Approaches
The analysis, which reviewed 37 of studies involving thousands of patients, compared the effects of these new drugs with older methods.
Scientists point out that individuals who shed pounds through diet and exercise typically see a less rapid weight regain—around 0.1 kg a month—after stopping.
Understanding the Quick Regain
Doctors believe the mode of action of the jabs accounts for the accelerated weight return.
The injections mimic a body's own chemical called GLP-1, which controls feelings of fullness.
"Artificially providing GLP-1 concentrations several times higher than normal may cause the system to generate a reduced amount of its own natural GLP-1, and may also reduce sensitivity to its effects," noted Dr. Adam Collins, a dietetics specialist.
"Discontinuation of this hormone supplement results in hunger is unsuppressed, making excessive eating far more likely."
A Lifelong Disease?
Medical guidelines advise the injections for people with obesity-related health risks, accompanied by recommended lifestyle changes.
Many experts say that, considering the significant potential of relapse, the treatment should be considered ongoing.
This opinion is echoed by drug manufacturers, who note that the findings "underscore the long-term character of obesity," akin to managing conditions like high blood pressure.
Patient Testimonies
People who have stopped the medication explain a sudden return of hunger.
"I experienced a trigger that goes on and I was suddenly starving," recalled one woman.
The struggle is worsened if patients have not established lasting lifestyle or habit changes during treatment.
Significant Adoption
Survey data show that a significant number of adults in the UK have tried these injections in the last 12 months, with demand being substantial.
- Adoption is more common among females compared to men.
- The 40s and 50s demographic shows the highest level of interest.
- Many obtain the medications through private prescriptions rather than public health services.
Finally, clinicians emphasize that while the jabs are potent tools for shedding pounds, they are not a permanent cure and lasting health benefits relies on integrated behavioural management.
