Users Stopping Slimming Injections Gain Back Weight at a Quadrupled Rate Compared to People Using Diet and Exercise
New research reveals that people who stop using blockbuster slimming jabs like semaglutide or tirzepatide tend to recover shed pounds at a significantly accelerated pace than those who end traditional diet and exercise regimens.
Findings released in a major health publication points out that while overweight individuals often shed substantial amounts of their total mass while on the medication, the mass returns at an average rate of nearly a kilo each month once they quit.
"Users buying these treatments must be informed of the risk of quick rebound weight gain when the therapy concludes," warns lead investigator Dr. Susan Jebb.
Such speed of regain suggests a return to pre-treatment mass in about one and a half years.
Weighing Treatments
The study, which reviewed 37 of trials involving thousands of patients, contrasted the results of GLP-1 agonists with other pills.
Researchers emphasize that people who shed pounds through dieting typically have a less rapid weight regain—perhaps 100 grams monthly—post-intervention.
Explaining the Quick Rebound
Experts believe the way of the jabs is key to understanding the amplified regain.
The injections imitate a body's own chemical called glucagon-like peptide-1, which helps regulate appetite.
"Sustained high doses of GLP-1 levels several times higher than normal may cause the body to produce less of its endogenous GLP-1, and may also diminish responsiveness to its effects," noted Dr. Adam Collins, a dietetics specialist.
"Withdrawal of this GLP-1 'fix' leads to appetite is unsuppressed, making excessive eating far more likely."
A Chronic Disease?
Health authorities advise the injections for people with weight-linked medical conditions, alongside prescribed diet and exercise modifications.
A number of clinicians argue that, due to the likelihood of weight regain, the treatment is often ongoing.
This perspective is echoed by pharmaceutical companies, who say that the findings "underscore the long-term character of obesity," akin to managing diseases like high blood pressure.
User Experiences
Users who have stopped the jabs explain a powerful return of hunger.
"It was like a trigger activating and I was suddenly ravenous," described a patient.
This difficulty is compounded if users have not established lasting lifestyle or habit changes during treatment.
Widespread Adoption
Recent estimates suggest that millions of adults in the UK have tried weight-loss jabs in the past year, with demand remaining high.
- Adoption is higher among females than men.
- The middle-aged age group shows the highest level of interest.
- Many access the drugs through private prescriptions rather than the NHS.
Finally, researchers caution that while the jabs are potent agents for weight loss, they are not a magic solution and long-term success relies on combined lifestyle support.
