Fresh analysis reveals that people who discontinue popular weight-loss injections like Wegovy and Mounjaro may regain lost weight at a significantly accelerated pace than those who end traditional lifestyle programs.
Published data in a major medical journal demonstrates that while overweight people can lose about a fifth of their total mass while on the medication, the mass is regained at an estimated rate of nearly a kilo each month upon discontinuation.
"Individuals purchasing such drugs should be aware of the risk of rapid rebound weight gain when the medication is stopped," warns researcher Dr. Susan Jebb.
This pace of regain suggests a reversion to original weight in about one and a half years.
Weighing Therapies
The research, which looked at dozens of studies involving thousands of patients, compared the effects of GLP-1 agonists with older methods.
Researchers point out that people who lose weight through diet and exercise usually experience a slower creep back—perhaps 0.1 kg a month—once they finish.
Understanding the Rapid Regain
Doctors believe the way of the drugs explains the accelerated weight return.
The injections mimic a natural hormone called GLP-1, which controls feelings of fullness.
"Sustained high doses of GLP-1 concentrations far above than the body's typical production may cause the body to generate a reduced amount of its own natural hormone, and could reduce sensitivity to its actions," explained Dr. Adam Collins, a nutrition expert.
"Discontinuation of this hormone supplement results in appetite is unsuppressed, making binge eating a significant risk."
A Chronic Issue?
Medical guidelines suggest the injections for individuals with weight-linked medical conditions, accompanied by recommended lifestyle changes.
A number of clinicians argue that, considering the significant potential of weight regain, the therapy is often life-long.
This opinion is echoed by pharmaceutical companies, who say that the findings "underscore the long-term nature of excess weight," similar to managing conditions like hypertension.
User Testimonies
Users who have come off the jabs explain a intense return of appetite.
"It felt as if a trigger activating and you become starving," said an individual.
The struggle is compounded if users have not developed lasting lifestyle or habit changes during therapy.
Growing Use
Survey data suggest that a significant number of adults in the UK have tried weight-loss jabs in the past year, with demand continuing to grow.
- Adoption is higher among females compared to males.
- The middle-aged age group shows the greatest usage rates.
- A large proportion access the drugs through private prescriptions rather than public health services.
Finally, experts emphasize that while GLP-1 drugs are powerful tools for shedding pounds, they are not a magic cure and maintained weight loss likely depends on ongoing lifestyle changes.
