New research suggests that people who stop using blockbuster slimming jabs like Mounjaro or Wegovy tend to recover reduced body mass much more quickly than those who halt traditional diet and exercise programs.
Published data in a prominent medical journal shows that while overweight individuals frequently drop substantial amounts of their body weight while undergoing treatment, the mass is regained at an average rate of nearly a kilo each month upon discontinuation.
"People buying these medications should be informed of the risk of rapid rebound weight gain when the treatment is stopped," stated expert Dr. Susan Jebb.
This pace of recovery means a reversion to starting mass in about one and a half years.
Weighing Therapies
The research, which looked at 37 of trials involving over 9,000 of patients, compared the results of GLP-1 agonists with other pills.
The team emphasize that people who lose weight through lifestyle changes alone generally see a less rapid weight regain—perhaps 0.1 kg a month—once they finish.
The Reason for the Rapid Rebound
Doctors propose the mode of action of the jabs explains the amplified regain.
The injections copy a natural hormone called glucagon-like peptide-1, which controls appetite.
"Artificially providing GLP-1 levels several times higher than normal may cause the body to produce less of its own natural GLP-1, and could lessen sensitivity to its actions," said Dr. Adam Collins, a dietetics specialist.
"Discontinuation of this hormone supplement leads to appetite is no longer kept in check, making excessive eating a significant risk."
An Ongoing Disease?
Health authorities suggest the jabs for individuals with weight-linked medical conditions, accompanied by prescribed diet and exercise modifications.
Professionals argue that, due to the significant potential of relapse, the treatment might need to be life-long.
This view is reinforced by drug manufacturers, who state that the findings "emphasize the chronic character of excess weight," similar to managing conditions like diabetes.
Patient Testimonies
Individuals who have come off the jabs report a intense resurgence of hunger.
"It felt as if a switch activating and you're instantly ravenous," said an individual.
The struggle is compounded if individuals have not adopted sustainable dietary or behavioural changes during therapy.
Significant Use
Survey data suggest that millions of people in the UK have tried these injections in the last 12 months, with interest continuing to grow.
- Use is greater among women compared to men.
- The 40s and 50s age group shows the highest level of interest.
- Many access the drugs through private healthcare rather than the NHS.
In conclusion, clinicians stress that while GLP-1 drugs are powerful agents for weight loss, they are not a magic solution and long-term success likely depends on integrated behavioural changes.
