New research reveals that individuals who stop using new GLP-1 drugs like semaglutide or tirzepatide tend to recover shed pounds much more quickly than those who halt conventional lifestyle regimens.
Research printed in a leading medical journal points out that while overweight individuals frequently drop a large proportion of their total mass while on the medication, the mass returns at an estimated rate of 0.8 kg per month once they quit.
"Individuals buying these medications must be aware of the danger of rapid weight regain when the therapy ends," warns researcher Dr. Susan Jebb.
This pace of regain implies a return to starting weight in about one and a half years.
Comparing Treatments
The research, which reviewed dozens of studies involving over 9,000 of patients, contrasted the effects of GLP-1 agonists with older methods.
Researchers point out that individuals who lose weight through dieting typically see a more gradual weight regain—perhaps 100 grams monthly—once they finish.
The Reason for the Quick Rebound
Experts believe the mode of action of the jabs explains the heightened rebound.
These medications copy a body's own chemical called glucagon-like peptide-1, which controls hunger.
"Artificially providing the hormone levels several times higher than the body's typical production could lead to the body to generate a reduced amount of its own natural GLP-1, and could reduce sensitivity to its actions," noted Dr. Adam Collins, a nutrition expert.
"Discontinuation of this medication means appetite is no longer kept in check, making excessive eating far more likely."
A Chronic Issue?
Medical guidelines suggest the injections for individuals with weight-linked health risks, alongside recommended lifestyle changes.
Professionals contend that, due to the high risk of weight regain, the therapy might need to be life-long.
This view is reinforced by pharmaceutical companies, who note that the findings "underscore the long-term nature of excess weight," similar to managing conditions like high blood pressure.
User Experiences
Individuals who have come off the jabs describe a intense resurgence of cravings.
"It was like something activating and I was suddenly starving," said an individual.
This challenge is compounded if individuals have not adopted sustainable lifestyle or habit changes during therapy.
Growing Use
Survey data show that millions of adults in the UK have used weight-loss jabs in the past year, with demand remaining high.
- Use is more common among females compared to men.
- The 40s and 50s demographic shows the highest level of interest.
- Many access the drugs through private healthcare rather than the NHS.
In conclusion, clinicians emphasize that while these medications are powerful tools for shedding pounds, they are not a standalone fix and lasting health benefits likely depends on combined lifestyle management.
