Fresh analysis indicates that patients who come off blockbuster slimming jabs like semaglutide or tirzepatide may regain lost weight at a significantly accelerated pace than those who halt traditional diet and exercise plans.
Published data in a leading medical journal demonstrates that while overweight people frequently drop substantial amounts of their total mass while on the medication, the mass is regained at an estimated rate of nearly a kilo each month upon discontinuation.
"Individuals using these medications need to be cognizant of the potential of quick rebound weight gain when the therapy is stopped," warns lead investigator Dr. Susan Jebb.
Such speed of recovery implies a reversion to starting mass within about a year and a half.
Comparing Approaches
The analysis, which reviewed 37 of studies involving thousands of participants, compared the effects of these new drugs with other pills.
Researchers point out that people who shed pounds through dieting generally experience a slower weight regain—around 0.1 kg a month—once they finish.
Explaining the Rapid Regain
Experts suggest the way of the injections explains the accelerated weight return.
These medications mimic a body's own chemical called GLP-1, which controls appetite.
"Artificially providing the hormone levels far above than normal may cause the body to produce less of its own natural hormone, and may also diminish responsiveness to its actions," said Dr. Adam Collins, a nutrition expert.
"Withdrawal of this hormone supplement means appetite is unsuppressed, making overeating far more likely."
An Ongoing Disease?
Medical guidelines advise the injections for people with weight-linked health risks, alongside prescribed lifestyle changes.
Many experts say that, considering the likelihood of relapse, the treatment should be considered long-term.
This view is echoed by drug manufacturers, who state that the results "emphasize the persistent character of excess weight," similar to managing conditions like high blood pressure.
User Testimonies
Individuals who have discontinued the medication describe a sudden resurgence of appetite.
"It felt as if a trigger activating and I was suddenly ravenous," described an individual.
This challenge is worsened if individuals have not adopted permanent lifestyle or habit changes during therapy.
Significant Adoption
Recent estimates suggest that millions of adults in the UK have used these injections in the last 12 months, with interest remaining high.
- Use is more common among females than males.
- The middle-aged age group shows the highest usage rates.
- Many access the medications through private prescriptions rather than the NHS.
Ultimately, researchers caution that while the jabs are potent tools for shedding pounds, they are not a permanent fix and long-term success relies on integrated lifestyle support.
