A recent study reveals that people who come off new GLP-1 drugs like Wegovy and Mounjaro may regain lost weight at a significantly accelerated pace than those who halt conventional lifestyle plans.
Findings released in a leading health publication points out that while obese individuals often shed substantial amounts of their total mass while undergoing treatment, the mass is regained at an average rate of 0.8 kg per month upon discontinuation.
"Individuals purchasing these treatments need to be cognizant of the potential of rapid rebound weight gain when the treatment concludes," cautioned researcher Dr. Susan Jebb.
This pace of recovery means a reversion to original weight within about a year and a half.
Comparing Treatments
The analysis, which examined 37 of studies involving thousands of participants, contrasted the effects of these new drugs with conventional dieting.
Scientists emphasize that individuals who shed pounds through dieting usually experience a less rapid weight regain—perhaps 100 grams monthly—once they finish.
Explaining the Rapid Regain
Nutrition scientists believe the mechanism of the drugs is key to understanding the heightened weight return.
The injections imitate a natural hormone called GLP-1, which moderates appetite.
"Artificially providing the hormone levels far above than normal may cause the system to produce less of its own natural GLP-1, and may also reduce sensitivity to its effects," said Dr. Adam Collins, a dietetics expert.
"Discontinuation of this hormone supplement leads to appetite is uncontrolled, making excessive eating far more likely."
An Ongoing Condition?
Medical guidelines recommend the jabs for individuals with obesity-related medical conditions, alongside prescribed diet and exercise modifications.
Professionals say that, given the likelihood of relapse, the treatment should be considered ongoing.
This view is supported by drug manufacturers, who say that the results "underscore the chronic nature of excess weight," similar to managing diseases like high blood pressure.
User Testimonies
Users who have stopped the jabs report a sudden return of hunger.
"I experienced a trigger that goes on and you become extremely hungry," recalled one woman.
The struggle is worsened if individuals have not established permanent lifestyle or habit changes during treatment.
Significant Interest
Survey data indicate that a significant number of adults in the UK have used weight-loss jabs in the last 12 months, with desire being substantial.
- Adoption is more common among women compared to men.
- The middle-aged demographic shows the highest level of interest.
- A large proportion access the drugs through private prescriptions rather than public health services.
Finally, clinicians emphasize that while the jabs are effective tools for shedding pounds, they are not a standalone fix and lasting health benefits likely depends on combined lifestyle management.
