A recent study indicates that individuals who stop using blockbuster slimming jabs like semaglutide or tirzepatide tend to recover reduced body mass far faster than those who halt conventional lifestyle programs.
Findings released in a prominent health publication demonstrates that while overweight people frequently drop substantial amounts of their total mass while undergoing treatment, the weight returns at an estimated rate of 0.8 kg per month after stopping.
"People buying these drugs must be informed of the potential of rapid rebound weight gain when the treatment ends," stated lead investigator Dr. Susan Jebb.
That rate of regain suggests a reversion to starting weight in about a year and a half.
Comparing Treatments
The study, which examined dozens of studies involving over 9,000 of participants, compared the effects of these new drugs with older methods.
The team point out that people who lose weight through diet and exercise typically see a more gradual weight regain—perhaps 0.1 kg a month—after stopping.
The Reason for the Quick Regain
Experts suggest the mode of action of the injections is key to understanding the amplified rebound.
GLP-1 drugs mimic a body's own chemical called GLP-1, which moderates hunger.
"Artificially providing GLP-1 concentrations several times higher than normal could lead to the system to produce less of its endogenous hormone, and could reduce responsiveness to its effects," said Dr. Adam Collins, a dietetics researcher.
"Withdrawal of this GLP-1 'fix' means appetite is no longer kept in check, making overeating much more probable."
A Lifelong Disease?
Health authorities recommend the injections for individuals with obesity-related health risks, alongside recommended diet and exercise modifications.
A number of clinicians contend that, due to the likelihood of relapse, the treatment is often long-term.
This perspective is echoed by drug manufacturers, who say that the results "highlight the persistent character of excess weight," comparing it to managing conditions like high blood pressure.
Patient Accounts
Users who have stopped the jabs describe a sudden return of cravings.
"I experienced a trigger activating and you're instantly starving," described one woman.
This difficulty is exacerbated if individuals have not adopted lasting dietary or behavioural modifications during therapy.
Growing Interest
Survey data show that millions of people in the UK have tried these injections in the past year, with interest continuing to grow.
- Use is higher among women than males.
- The 40s and 50s age group shows the greatest usage rates.
- Many access the medications through private prescriptions rather than the NHS.
In conclusion, experts caution that while these medications are effective tools for weight loss, they are not a magic solution and maintained weight loss likely depends on combined lifestyle changes.
