Fresh analysis reveals that individuals who discontinue new slimming jabs like semaglutide or tirzepatide can put back on reduced body mass at a significantly accelerated pace than those who halt traditional diet and exercise regimens.
Published data in a prominent health publication demonstrates that while obese individuals frequently drop about a fifth of their total mass while on the medication, the mass returns at an estimated rate of nearly a kilo each month upon discontinuation.
"Individuals using such medications should be cognizant of the potential of rapid weight regain when the treatment concludes," stated researcher Dr. Susan Jebb.
Such speed of recovery means a reversion to original weight in about a year and a half.
Analyzing Approaches
The analysis, which examined dozens of studies involving thousands of patients, contrasted the results of GLP-1 agonists with conventional dieting.
Researchers note that people who lose weight through lifestyle changes alone typically experience a more gradual creep back—around 0.1 kg a month—after stopping.
Understanding the Quick Rebound
Doctors propose the way of the drugs explains the accelerated rebound.
GLP-1 drugs imitate a body's own chemical called glucagon-like peptide-1, which moderates hunger.
"Long-term administration of GLP-1 levels several times higher than normal might result in the body to produce less of its own natural GLP-1, and may also diminish responsiveness to its actions," explained Dr. Adam Collins, a dietetics specialist.
"Withdrawal of this medication leads to hunger is no longer kept in check, making binge eating much more probable."
A Chronic Condition?
Health authorities recommend the injections for people with weight-linked medical conditions, accompanied by recommended diet and exercise modifications.
Professionals say that, given the likelihood of weight regain, the therapy should be considered life-long.
This view is supported by drug manufacturers, who say that the findings "underscore the long-term character of excess weight," similar to managing diseases like high blood pressure.
User Testimonies
People who have stopped the medication explain a sudden resurgence of cravings.
"It was like something flipping and you become extremely hungry," recalled a patient.
The struggle is exacerbated if patients have not developed permanent dietary or behavioural modifications during therapy.
Growing Use
Survey data show that millions of people in the UK have tried these injections in the last 12 months, with desire being substantial.
- Use is greater among women than males.
- The 40s and 50s demographic shows the greatest level of interest.
- Many obtain the medications through private prescriptions rather than the NHS.
Ultimately, researchers caution that while these medications are powerful agents for shedding pounds, they are not a magic cure and long-term success likely depends on ongoing lifestyle support.
