Fresh analysis reveals that patients who stop using blockbuster slimming jabs like Wegovy and Mounjaro may regain shed pounds far faster than those who stop conventional lifestyle regimens.
Published data in a leading health publication points out that while overweight individuals frequently drop substantial amounts of their total mass while using the jabs, the mass comes back at an estimated rate of 0.8 kg per month after stopping.
"Individuals buying these drugs should be cognizant of the potential of fast rebound weight gain when the treatment ends," warns researcher Dr. Susan Jebb.
That rate of regain suggests a return to original weight within about 18 months.
Comparing Treatments
The study, which examined 37 of trials involving over 9,000 of patients, compared the effects of GLP-1 agonists with conventional dieting.
Scientists point out that individuals who shed pounds through dieting generally have a slower weight regain—around 100 grams monthly—once they finish.
Explaining the Fast Rebound
Nutrition scientists suggest the way of the jabs is key to understanding the accelerated rebound.
The injections imitate a natural hormone called glucagon-like peptide-1, which controls hunger.
"Long-term administration of the hormone levels several times higher than normal might result in the body to produce less of its endogenous hormone, and could lessen sensitivity to its actions," explained Dr. Adam Collins, a nutrition expert.
"Withdrawal of this GLP-1 'fix' results in hunger is uncontrolled, making excessive eating far more likely."
A Lifelong Condition?
Health authorities suggest the jabs for people with obesity-related medical conditions, accompanied by prescribed lifestyle changes.
Many experts say that, considering the significant potential of weight regain, the treatment should be considered ongoing.
This opinion is reinforced by drug manufacturers, who note that the results "emphasize the long-term nature of obesity," similar to managing conditions like hypertension.
Patient Experiences
Users who have stopped the jabs explain a powerful resurgence of appetite.
"I experienced a switch that goes on and you're instantly starving," recalled one woman.
This difficulty is worsened if users have not established permanent lifestyle or habit modifications during treatment.
Widespread Adoption
Recent estimates show that a significant number of adults in the UK have tried these injections in the past year, with demand being substantial.
- Adoption is higher among women than men.
- The middle-aged age group shows the greatest usage rates.
- Many access the medications through private healthcare rather than public health services.
In conclusion, clinicians emphasize that while the jabs are powerful tools for weight loss, they are not a permanent cure and lasting health benefits relies on ongoing behavioural changes.
