Fresh analysis reveals that individuals who discontinue new GLP-1 drugs like Wegovy and Mounjaro can put back on lost weight at a significantly accelerated pace than those who end conventional diet and exercise regimens.
Research printed in a major health publication demonstrates that while overweight individuals often shed substantial amounts of their total mass while on the medication, the weight is regained at an estimated rate of 0.8 kg per month once they quit.
"Individuals using these treatments must be cognizant of the danger of rapid rebound weight gain when the therapy ends," warns expert Dr. Susan Jebb.
That rate of recovery implies a reversion to starting weight within about a year and a half.
Analyzing Treatments
The analysis, which reviewed 37 of studies involving thousands of patients, compared the effects of the injectable medications with conventional dieting.
Researchers note that individuals who lose weight through lifestyle changes alone typically have a slower creep back—approximately 0.1 kg a month—post-intervention.
The Reason for the Fast Regain
Doctors believe the way of the injections is key to understanding the heightened rebound.
GLP-1 drugs imitate a body's own chemical called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Long-term administration of GLP-1 concentrations several times higher than the body's typical production might result in the body to produce less of its endogenous hormone, and could diminish sensitivity to its actions," explained Dr. Adam Collins, a nutrition expert.
"Stopping of this medication results in hunger is uncontrolled, making excessive eating much more probable."
An Ongoing Disease?
The NHS suggest the injections for people with weight-linked health risks, accompanied by prescribed lifestyle changes.
Many experts say that, considering the high risk of weight regain, the therapy should be considered long-term.
This opinion is echoed by pharmaceutical companies, who state that the results "underscore the chronic character of obesity," similar to managing diseases like hypertension.
User Accounts
People who have stopped the jabs describe a sudden resurgence of cravings.
"It felt as if a switch that goes on and I was suddenly starving," recalled a patient.
This challenge is exacerbated if patients have not developed sustainable lifestyle or habit modifications during therapy.
Widespread Adoption
Figures indicate that millions of people in the UK have tried these injections in the last 12 months, with demand remaining high.
- Use is greater among females compared to men.
- The 40s and 50s age group shows the greatest usage rates.
- Many access the medications through private healthcare rather than the NHS.
In conclusion, experts stress that while these medications are effective tools for shedding pounds, they are not a standalone cure and long-term success likely depends on ongoing lifestyle support.
