Fresh analysis indicates that patients who discontinue new weight-loss injections like Wegovy and Mounjaro can put back on reduced body mass far faster than those who end conventional lifestyle plans.
Research printed 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 after stopping.
"Individuals using such drugs need to be aware of the danger of quick rebound weight gain when the treatment ends," warns researcher Dr. Susan Jebb.
That rate of recovery means a return to starting mass within about 18 months.
Analyzing Treatments
The research, which examined dozens of studies involving thousands of patients, compared the effects of these new drugs with other pills.
Scientists point out that individuals who lose weight through dieting generally experience a more gradual weight regain—perhaps 0.1 kg a month—once they finish.
Understanding the Quick Regain
Nutrition scientists believe the mechanism of the jabs explains the accelerated rebound.
The injections copy a natural hormone called glucagon-like peptide-1, which controls appetite.
"Long-term administration of the hormone concentrations far above than the body's typical production could lead to the body to produce less of its endogenous GLP-1, and may also reduce responsiveness to its actions," said Dr. Adam Collins, a dietetics expert.
"Stopping of this medication results in hunger is unsuppressed, making binge eating much more probable."
An Ongoing Issue?
Health authorities suggest the injections for individuals with weight-linked health risks, alongside prescribed diet and exercise modifications.
Professionals say that, considering the high risk of weight regain, the treatment should be considered long-term.
This opinion is reinforced by drug manufacturers, who state that the findings "emphasize the long-term character of obesity," similar to managing conditions like diabetes.
Patient Testimonies
People who have stopped the medication describe a sudden return of hunger.
"It felt as if a switch that goes on and you become extremely hungry," said one woman.
This challenge is compounded if users have not developed lasting lifestyle or habit modifications during treatment.
Widespread Use
Figures suggest that a significant number of adults in the UK have tried weight-loss jabs in the last 12 months, with interest remaining high.
- Adoption is higher among females than men.
- The 40s and 50s age group shows the highest level of interest.
- Many obtain the drugs through private healthcare rather than the NHS.
In conclusion, researchers emphasize that while the jabs are powerful agents for weight loss, they are not a magic cure and lasting health benefits hinges on ongoing lifestyle support.
