Fresh analysis suggests that individuals who come off blockbuster slimming jabs like Wegovy and Mounjaro may regain shed pounds far faster than those who stop traditional lifestyle regimens.
Published data in a leading health publication points out that while overweight individuals frequently drop about a fifth of their total mass while on the medication, the weight comes back at an estimated rate of 0.8 kg per month after stopping.
"Individuals purchasing these medications must be cognizant of the danger of fast rebound weight gain when the therapy ends," cautioned expert Dr. Susan Jebb.
This pace of regain implies a reversion to pre-treatment weight within about a year and a half.
Weighing Treatments
The study, which examined dozens of studies involving over 9,000 of patients, contrasted the outcomes of these new drugs with other pills.
Scientists note that people who lose weight through lifestyle changes alone generally see a less rapid weight regain—perhaps 100 grams monthly—once they finish.
Understanding the Rapid Rebound
Experts believe the mechanism of the drugs accounts for the amplified weight return.
The injections imitate a natural hormone called GLP-1, which controls appetite.
"Artificially providing GLP-1 concentrations far above than normal might result in the system to generate a reduced amount of its own natural hormone, and could lessen responsiveness to its actions," explained Dr. Adam Collins, a nutrition researcher.
"Stopping of this medication results in appetite is uncontrolled, making overeating a significant risk."
A Lifelong Disease?
Health authorities recommend the jabs for individuals with weight-linked health risks, alongside recommended lifestyle changes.
Many experts contend that, due to the likelihood of weight regain, the therapy should be considered ongoing.
This view is reinforced by drug manufacturers, who state that the findings "underscore the long-term nature of excess weight," akin to managing conditions like hypertension.
Patient Experiences
Users who have come off the jabs report a intense return of cravings.
"It was like a switch that goes on and you become extremely hungry," said an individual.
The struggle is exacerbated if users have not adopted sustainable dietary or behavioural changes during therapy.
Growing Adoption
Survey data suggest that a significant number of people in the UK have tried weight-loss jabs in the past year, with demand continuing to grow.
- Use is higher among women than men.
- The 40s and 50s age group shows the highest usage rates.
- Many obtain the drugs through private prescriptions rather than the NHS.
In conclusion, experts caution that while these medications are potent agents for weight loss, they are not a magic cure and maintained weight loss relies on ongoing lifestyle support.
