A recent study indicates that people who stop using blockbuster slimming jabs like Mounjaro or Wegovy tend to recover lost weight much more quickly than those who end conventional lifestyle programs.
Published data in a leading medical journal demonstrates that while overweight individuals frequently drop about a fifth of their total mass while on the medication, the weight is regained at an estimated rate of 0.8 kg per month upon discontinuation.
"People buying such medications should be cognizant of the risk of rapid rebound weight gain when the treatment ends," warns lead investigator Dr. Susan Jebb.
Such speed of recovery means a return to original weight within about one and a half years.
Comparing Approaches
The research, which reviewed dozens of studies involving thousands of patients, contrasted the outcomes of GLP-1 agonists with older methods.
Researchers note that people who shed pounds through diet and exercise typically experience a slower creep back—perhaps 0.1 kg a month—once they finish.
Explaining the Quick Regain
Nutrition scientists suggest the way of the injections is key to understanding the heightened weight return.
GLP-1 drugs mimic a body's own chemical called glucagon-like peptide-1, which moderates appetite.
"Sustained high doses of GLP-1 concentrations several times higher than normal might result in the system to produce less of its endogenous hormone, and may also diminish responsiveness to its effects," noted Dr. Adam Collins, a dietetics specialist.
"Discontinuation of this medication leads to appetite is uncontrolled, making binge eating far more likely."
A Lifelong Disease?
Health authorities recommend the injections for individuals with weight-linked medical conditions, accompanied by recommended lifestyle changes.
Many experts contend that, due to the likelihood of weight regain, the treatment is often ongoing.
This perspective is reinforced by pharmaceutical companies, who say that the findings "highlight the persistent character of obesity," akin to managing conditions like high blood pressure.
User Experiences
People who have discontinued the jabs describe a sudden return of appetite.
"I experienced a switch that goes on and I was suddenly ravenous," described an individual.
This difficulty is worsened if users have not established sustainable dietary or behavioural changes during treatment.
Growing Interest
Survey data indicate that a significant number of people in the UK have tried weight-loss jabs in the past year, with demand remaining high.
- Use is greater among females compared to men.
- The middle-aged demographic shows the highest usage rates.
- Many obtain the medications through private prescriptions rather than the NHS.
In conclusion, experts stress that while the jabs are potent agents for weight loss, they are not a standalone cure and maintained weight loss relies on combined behavioural support.
