Fresh analysis indicates that individuals who come off blockbuster slimming jabs like semaglutide or tirzepatide can put back on lost weight much more quickly than those who halt conventional lifestyle plans.
Research printed in a prominent health publication demonstrates that while obese people can lose a large proportion of their body weight while on the medication, the mass comes back at an average rate of nearly a kilo each month after stopping.
"People purchasing these medications should be cognizant of the risk of fast weight regain when the treatment is stopped," cautioned lead investigator Dr. Susan Jebb.
That rate of recovery means a reversion to starting weight within about one and a half years.
Analyzing Approaches
The study, which examined 37 of trials involving thousands of participants, contrasted the results of GLP-1 agonists with conventional dieting.
Researchers note that individuals who lose weight through diet and exercise typically experience a more gradual weight regain—perhaps 100 grams monthly—after stopping.
Explaining the Quick Rebound
Doctors believe the mechanism of the injections explains the heightened regain.
These medications mimic a body's own chemical called GLP-1, which controls appetite.
"Artificially providing the hormone concentrations several times higher than normal may cause the system to produce less of its endogenous GLP-1, and could reduce responsiveness to its actions," said Dr. Adam Collins, a dietetics expert.
"Withdrawal of this hormone supplement leads to hunger is unsuppressed, making overeating far more likely."
An Ongoing Disease?
The NHS suggest the jabs for people with weight-linked medical conditions, accompanied by recommended diet and exercise modifications.
Professionals say that, considering the high risk of weight regain, the therapy should be considered long-term.
This perspective is supported by drug manufacturers, who say that the results "emphasize the chronic nature of obesity," similar to managing diseases like high blood pressure.
User Testimonies
Individuals who have stopped the medication describe a sudden resurgence of hunger.
"It was like a trigger that goes on and I was suddenly extremely hungry," recalled an individual.
This challenge is exacerbated if individuals have not established permanent lifestyle or habit changes during treatment.
Widespread Interest
Recent estimates show that a significant number of people in the UK have used weight-loss jabs in the last 12 months, with interest continuing to grow.
- Use is higher among women compared to men.
- The middle-aged age group shows the highest level of interest.
- A large proportion obtain the medications through private healthcare rather than the NHS.
Finally, researchers emphasize that while the jabs are powerful agents for shedding pounds, they are not a magic cure and long-term success relies on ongoing behavioural management.
