New research indicates that people who come off new weight-loss injections like Mounjaro or Wegovy may regain shed pounds at a significantly accelerated pace than those who stop conventional diet and exercise programs.
Research printed in a leading medical journal demonstrates that while overweight individuals often shed a large proportion of their body weight while undergoing treatment, the mass is regained at an estimated rate of 0.8 kg per month once they quit.
"People purchasing such medications should be informed of the risk of fast rebound weight gain when the treatment is stopped," stated expert Dr. Susan Jebb.
This pace of recovery implies a reversion to starting weight in about a year and a half.
Weighing Approaches
The analysis, which reviewed 37 of studies involving thousands of patients, contrasted the outcomes of the injectable medications with older methods.
Researchers note that people who shed pounds through diet and exercise usually see a more gradual weight regain—perhaps 0.1 kg a month—post-intervention.
Explaining the Rapid Regain
Nutrition scientists propose the mechanism of the injections accounts for the amplified rebound.
These medications mimic a natural hormone called GLP-1, which controls appetite.
"Long-term administration of the hormone concentrations several times higher than normal may cause the system to generate a reduced amount of its endogenous GLP-1, and may also diminish sensitivity to its actions," explained Dr. Adam Collins, a dietetics researcher.
"Discontinuation of this GLP-1 'fix' results in appetite is unsuppressed, making overeating much more probable."
A Chronic Issue?
Health authorities recommend the jabs for individuals with obesity-related health risks, accompanied by prescribed lifestyle changes.
A number of clinicians say that, considering the significant potential of relapse, the therapy might need to be long-term.
This opinion is supported by pharmaceutical companies, who state that the results "underscore the chronic nature of excess weight," akin to managing conditions like high blood pressure.
Patient Testimonies
People who have stopped the jabs describe a intense return of appetite.
"It felt as if a switch flipping and you're instantly extremely hungry," said an individual.
This difficulty is compounded if users have not adopted sustainable lifestyle or habit changes during treatment.
Growing Interest
Figures indicate that a significant number of people in the UK have tried weight-loss jabs in the past year, with interest continuing to grow.
- Adoption is more common among women compared to men.
- The middle-aged demographic shows the greatest level of interest.
- A large proportion obtain the medications through private prescriptions rather than the NHS.
Ultimately, experts emphasize that while GLP-1 drugs are effective agents for weight loss, they are not a permanent cure and maintained weight loss likely depends on ongoing behavioural management.
