A recent study indicates that individuals who discontinue new GLP-1 drugs like Wegovy and Mounjaro may regain reduced body mass at a significantly accelerated pace than those who stop conventional lifestyle programs.
Findings released in a leading medical journal points out that while overweight individuals often shed about a fifth of their total mass while undergoing treatment, the mass comes back at an estimated rate of nearly a kilo each month upon discontinuation.
"Individuals purchasing such treatments must be aware of the risk of rapid weight regain when the therapy ends," warns lead investigator Dr. Susan Jebb.
That rate of recovery implies a return to original weight in about a year and a half.
Comparing Approaches
The study, which examined 37 of studies involving over 9,000 of participants, compared the results of GLP-1 agonists with other pills.
Scientists note that people who shed pounds through lifestyle changes alone usually have a less rapid weight regain—perhaps 0.1 kg a month—once they finish.
The Reason for the Rapid Rebound
Nutrition scientists suggest the mechanism of the injections is key to understanding the heightened weight return.
These medications mimic a natural hormone called glucagon-like peptide-1, which helps regulate hunger.
"Sustained high doses of the hormone levels far above than the body's typical production may cause the system to generate a reduced amount of its endogenous GLP-1, and may also lessen sensitivity to its effects," noted Dr. Adam Collins, a nutrition expert.
"Stopping of this medication leads to appetite is no longer kept in check, making binge eating far more likely."
A Chronic Condition?
The NHS advise the injections for individuals with weight-linked health risks, accompanied by prescribed diet and exercise modifications.
Many experts say that, due to the high risk of relapse, the treatment should be considered long-term.
This perspective is reinforced by pharmaceutical companies, who note that the findings "underscore the persistent character of excess weight," akin to managing conditions like hypertension.
Patient Testimonies
People who have discontinued the medication describe a sudden resurgence of appetite.
"I experienced a switch activating and you become ravenous," recalled an individual.
The struggle is worsened if users have not developed permanent lifestyle or habit changes during treatment.
Significant Adoption
Recent estimates indicate that millions of adults in the UK have tried weight-loss jabs in the last 12 months, with desire continuing to grow.
- Adoption is higher among women compared to males.
- The middle-aged demographic shows the greatest usage rates.
- A large proportion access the drugs through private healthcare rather than the NHS.
In conclusion, researchers emphasize that while these medications are effective tools for shedding pounds, they are not a permanent cure and lasting health benefits likely depends on integrated lifestyle changes.
