Fresh analysis indicates that individuals who discontinue new slimming jabs like semaglutide or tirzepatide can put back on reduced body mass much more quickly than those who stop traditional diet and exercise programs.
Published data in a leading medical journal demonstrates that while overweight individuals frequently drop about a fifth of their body weight while using the jabs, the weight returns at an estimated rate of nearly a kilo each month after stopping.
"People purchasing these treatments should be aware of the risk of rapid weight regain when the treatment is stopped," warns researcher Dr. Susan Jebb.
Such speed of regain implies a return to original mass in about 18 months.
Comparing Treatments
The research, which reviewed 37 of trials involving thousands of patients, contrasted the outcomes of these new drugs with other pills.
Scientists emphasize that people who lose weight through lifestyle changes alone generally experience a more gradual creep back—perhaps 100 grams monthly—once they finish.
Explaining the Fast Rebound
Experts suggest the way of the injections accounts for the amplified regain.
The injections copy a natural hormone called GLP-1, which moderates feelings of fullness.
"Long-term administration of the hormone levels several times higher than normal could lead to the system to produce less of its endogenous GLP-1, and could reduce responsiveness to its effects," said Dr. Adam Collins, a nutrition researcher.
"Stopping of this hormone supplement leads to appetite is uncontrolled, making overeating much more probable."
A Chronic Disease?
Health authorities advise the jabs for individuals with weight-linked medical conditions, alongside prescribed lifestyle changes.
Professionals say that, considering the high risk of relapse, the therapy should be considered long-term.
This perspective is reinforced by drug manufacturers, who state that the results "emphasize the chronic nature of obesity," comparing it to managing conditions like diabetes.
Patient Testimonies
Individuals who have come off the medication report a sudden resurgence of hunger.
"It was like a trigger activating and you become ravenous," said an individual.
The struggle is compounded if patients have not established permanent lifestyle or habit changes during treatment.
Widespread Interest
Recent estimates suggest that a significant number of people in the UK have tried these injections in the past year, with desire remaining high.
- Use is higher among women compared to males.
- The middle-aged demographic shows the highest usage rates.
- A large proportion obtain the drugs through private healthcare rather than public health services.
Finally, experts caution that while the jabs are potent tools for weight loss, they are not a permanent fix and long-term success likely depends on combined behavioural support.
