Fresh analysis reveals that individuals who discontinue new GLP-1 drugs like Mounjaro or Wegovy may regain reduced body mass far faster than those who end conventional lifestyle regimens.
Research printed in a leading medical journal points out that while obese people often shed about a fifth of their total mass while on the medication, the weight returns at an average rate of nearly a kilo each month once they quit.
"People purchasing these drugs should be aware of the risk of quick rebound weight gain when the therapy ends," warns lead investigator Dr. Susan Jebb.
This pace of recovery suggests a reversion to original mass within about a year and a half.
Analyzing Approaches
The research, which examined dozens of studies involving thousands of patients, compared the results of GLP-1 agonists with other pills.
Scientists point out that individuals who lose weight through diet and exercise generally experience a more gradual creep back—perhaps 100 grams monthly—after stopping.
Understanding the Quick Regain
Nutrition scientists propose the mode of action of the jabs is key to understanding the accelerated regain.
The injections imitate a body's own chemical called glucagon-like peptide-1, which helps regulate appetite.
"Sustained high doses of the hormone concentrations far above than the body's typical production may cause the system to generate a reduced amount of its own natural hormone, and may also reduce responsiveness to its effects," said Dr. Adam Collins, a nutrition researcher.
"Stopping of this hormone supplement leads to appetite is no longer kept in check, making overeating a significant risk."
An Ongoing Issue?
Medical guidelines advise the jabs for individuals with weight-linked health risks, accompanied by prescribed diet and exercise modifications.
Professionals contend that, considering the significant potential of relapse, the treatment might need to be life-long.
This view is supported by pharmaceutical companies, who note that the findings "highlight the chronic character of obesity," akin to managing diseases like hypertension.
Patient Testimonies
Individuals who have discontinued the jabs describe a powerful return of appetite.
"It was like a trigger that goes on and you're instantly starving," said one woman.
The struggle is compounded if users have not established permanent lifestyle or habit changes during treatment.
Growing Interest
Figures suggest that a significant number of people in the UK have used these injections in the past year, with desire continuing to grow.
- Adoption is more common among females compared to males.
- The 40s and 50s demographic shows the greatest level of interest.
- Many obtain the drugs through private healthcare rather than the NHS.
Ultimately, experts stress that while GLP-1 drugs are effective agents for shedding pounds, they are not a magic cure and maintained weight loss relies on combined lifestyle changes.
