A recent study indicates that people who discontinue new weight-loss injections like semaglutide or tirzepatide can put back on lost weight much more quickly than those who stop traditional lifestyle programs.
Published data in a major medical journal shows that while overweight people frequently drop about a fifth of their body weight while on the medication, the weight is regained at an estimated rate of nearly a kilo each month once they quit.
"Individuals using these treatments should be aware of the potential of rapid weight regain when the therapy concludes," stated researcher Dr. Susan Jebb.
Such speed of recovery implies a return to pre-treatment mass in about a year and a half.
Analyzing Approaches
The study, which reviewed 37 of studies involving thousands of patients, compared the results of these new drugs with conventional dieting.
Scientists emphasize that people who shed pounds through diet and exercise generally experience a slower creep back—perhaps 100 grams monthly—once they finish.
Understanding the Rapid Regain
Experts believe the way of the injections is key to understanding the accelerated rebound.
The injections copy a natural hormone called GLP-1, which controls hunger.
"Long-term administration of the hormone concentrations several times higher than normal might result in the body to generate a reduced amount of its endogenous GLP-1, and could reduce responsiveness to its actions," explained Dr. Adam Collins, a dietetics specialist.
"Withdrawal of this GLP-1 'fix' results in appetite is unsuppressed, making binge eating a significant risk."
A Chronic Issue?
Health authorities recommend the jabs for people with obesity-related medical conditions, alongside recommended lifestyle changes.
Many experts say that, considering the likelihood of weight regain, the therapy should be considered long-term.
This perspective is reinforced by drug manufacturers, who note that the findings "emphasize the chronic character of obesity," akin to managing diseases like high blood pressure.
User Testimonies
Individuals who have discontinued the medication explain a powerful return of appetite.
"It was like a switch that goes on and you're instantly extremely hungry," described an individual.
The struggle is worsened if individuals have not adopted lasting lifestyle or habit changes during therapy.
Growing Adoption
Figures show that a significant number of people in the UK have used weight-loss jabs in the past year, with interest remaining high.
- Adoption is higher among women than males.
- The middle-aged demographic shows the greatest level of interest.
- Many access the drugs through private prescriptions rather than the NHS.
Finally, clinicians emphasize that while the jabs are effective agents for shedding pounds, they are not a magic cure and lasting health benefits relies on integrated lifestyle changes.
