A recent study reveals that individuals who discontinue popular GLP-1 drugs like Wegovy and Mounjaro may regain lost weight much more quickly than those who end traditional lifestyle regimens.
Findings released in a leading health publication shows that while obese individuals can lose about a fifth of their body weight while undergoing treatment, the mass comes back at an estimated rate of 0.8 kg per month after stopping.
"Individuals purchasing these drugs must be cognizant of the danger of fast rebound weight gain when the medication is stopped," cautioned expert Dr. Susan Jebb.
Such speed of regain means a reversion to original weight within about one and a half years.
Weighing Treatments
The research, which reviewed dozens of studies involving thousands of participants, compared the effects of the injectable medications with older methods.
Researchers emphasize that people who shed pounds through lifestyle changes alone typically see a less rapid creep back—perhaps 0.1 kg a month—once they finish.
Explaining the Fast Regain
Nutrition scientists believe the way of the jabs is key to understanding the heightened weight return.
The injections copy a natural hormone called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Sustained high doses of GLP-1 levels far above than normal may cause the body to generate a reduced amount of its own natural GLP-1, and could diminish sensitivity to its actions," explained Dr. Adam Collins, a dietetics expert.
"Discontinuation of this hormone supplement means appetite is no longer kept in check, making binge eating far more likely."
A Chronic Disease?
Health authorities advise the jabs for individuals with weight-linked health risks, accompanied by prescribed diet and exercise modifications.
A number of clinicians contend that, considering the significant potential of weight regain, the therapy might need to be long-term.
This view is supported by pharmaceutical companies, who state that the findings "emphasize the chronic character of excess weight," comparing it to managing diseases like diabetes.
User Testimonies
People who have stopped the medication report a sudden return of appetite.
"I experienced a trigger activating and you become ravenous," said a patient.
This difficulty is compounded if users have not developed lasting lifestyle or habit changes during treatment.
Growing Use
Survey data suggest that millions of people in the UK have tried these injections in the past year, with desire remaining high.
- Adoption is more common among women compared to men.
- The middle-aged demographic shows the greatest usage rates.
- Many obtain the drugs through private prescriptions rather than public health services.
Finally, experts stress that while the jabs are effective tools for weight loss, they are not a magic fix and lasting health benefits likely depends on combined behavioural management.
