Fresh analysis reveals that individuals who come off blockbuster slimming jabs like semaglutide or tirzepatide may regain reduced body mass at a significantly accelerated pace than those who halt conventional lifestyle plans.
Published data in a major medical journal shows that while obese individuals often shed about a fifth of their body weight while using the jabs, the mass comes back at an average rate of nearly a kilo each month upon discontinuation.
"Individuals using such treatments should be aware of the potential of fast weight regain when the therapy ends," warns lead investigator Dr. Susan Jebb.
Such speed of regain implies a reversion to pre-treatment weight in about one and a half years.
Analyzing Treatments
The study, which examined dozens of studies involving thousands of participants, contrasted the results of these new drugs with older methods.
Scientists emphasize that individuals who shed pounds through dieting usually have a slower weight regain—around 100 grams monthly—once they finish.
Understanding the Quick Regain
Doctors propose the way of the drugs explains the amplified regain.
GLP-1 drugs mimic a body's own chemical called GLP-1, which helps regulate appetite.
"Sustained high doses of GLP-1 levels far above than the body's typical production might result in the system to produce less of its own natural hormone, and could reduce responsiveness to its effects," noted Dr. Adam Collins, a nutrition researcher.
"Discontinuation of this medication means appetite is no longer kept in check, making excessive eating far more likely."
An Ongoing Disease?
Health authorities suggest the jabs for people with obesity-related medical conditions, alongside recommended diet and exercise modifications.
A number of clinicians contend that, given the high risk of weight regain, the treatment might need to be long-term.
This opinion is supported by drug manufacturers, who say that the findings "underscore the persistent nature of excess weight," similar to managing diseases like high blood pressure.
Patient Experiences
People who have discontinued the medication explain a intense resurgence of cravings.
"It was like something flipping and you're instantly starving," said a patient.
This difficulty is exacerbated if users have not adopted permanent lifestyle or habit changes during treatment.
Significant Interest
Recent estimates show that a significant number of adults in the UK have used weight-loss jabs in the past year, with desire continuing to grow.
- Use is higher among women compared to males.
- The middle-aged age group shows the greatest level of interest.
- Many access the drugs through private prescriptions rather than the NHS.
In conclusion, researchers emphasize that while the jabs are effective agents for weight loss, they are not a standalone fix and lasting health benefits hinges on combined behavioural changes.
