New research indicates that people who stop using new slimming jabs like Wegovy and Mounjaro may regain lost weight far faster than those who stop traditional diet and exercise regimens.
Published data in a leading medical journal shows that while overweight people often shed substantial amounts of their total mass while undergoing treatment, the mass comes back at an average rate of 0.8 kg per month once they quit.
"Individuals using such drugs should be aware of the danger of rapid weight regain when the medication ends," stated expert Dr. Susan Jebb.
That rate of recovery implies a reversion to pre-treatment weight in about one and a half years.
Analyzing Approaches
The analysis, which looked at dozens of studies involving over 9,000 of participants, compared the outcomes of GLP-1 agonists with older methods.
Scientists point out that individuals who shed pounds through lifestyle changes alone typically have a more gradual weight regain—perhaps 100 grams monthly—once they finish.
The Reason for the Fast Regain
Experts believe the way of the drugs accounts for the accelerated weight return.
The injections mimic a natural hormone called glucagon-like peptide-1, which moderates hunger.
"Artificially providing GLP-1 levels several times higher than normal might result in the system to generate a reduced amount of its endogenous GLP-1, and may also lessen sensitivity to its effects," explained Dr. Adam Collins, a nutrition expert.
"Discontinuation of this hormone supplement leads to appetite is no longer kept in check, making binge eating much more probable."
A Chronic Disease?
Health authorities suggest the injections for people with weight-linked medical conditions, accompanied by recommended lifestyle changes.
Many experts say that, due to the likelihood of weight regain, the therapy might need to be life-long.
This view is echoed by pharmaceutical companies, who note that the results "emphasize the long-term character of excess weight," akin to managing conditions like high blood pressure.
Patient Testimonies
Individuals who have discontinued the jabs describe a intense resurgence of cravings.
"I experienced something activating and you become extremely hungry," described a patient.
This difficulty is compounded if individuals have not established lasting dietary or behavioural changes during therapy.
Widespread Use
Survey data show that millions of people in the UK have tried these injections in the last 12 months, with interest being substantial.
- Adoption is higher among women compared to males.
- The middle-aged age group shows the greatest usage rates.
- Many access the drugs through private prescriptions rather than public health services.
Finally, experts emphasize that while the jabs are effective agents for shedding pounds, they are not a magic solution and lasting health benefits hinges on ongoing lifestyle support.
