A recent study indicates that patients who come off blockbuster weight-loss injections like semaglutide or tirzepatide may regain shed pounds far faster than those who stop traditional diet and exercise regimens.
Findings released in a prominent health publication shows that while obese individuals often shed substantial amounts of their total mass while undergoing treatment, the weight comes back at an average rate of nearly a kilo each month upon discontinuation.
"Users purchasing these drugs need to be cognizant of the risk of fast rebound weight gain when the treatment concludes," warns lead investigator Dr. Susan Jebb.
Such speed of regain implies a return to starting mass in about one and a half years.
Comparing Treatments
The study, which looked at dozens of trials involving thousands of patients, contrasted the results of these new drugs with older methods.
Scientists point out that individuals who lose weight through lifestyle changes alone generally have a slower creep back—around 0.1 kg a month—after stopping.
The Reason for the Rapid Rebound
Experts believe the mode of action of the injections explains the heightened rebound.
The injections mimic a body's own chemical called glucagon-like peptide-1, which moderates appetite.
"Artificially providing GLP-1 concentrations far above than normal might result in the body to generate a reduced amount of its own natural hormone, and may also lessen responsiveness to its effects," noted Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this hormone supplement leads to hunger is no longer kept in check, making excessive eating far more likely."
An Ongoing Disease?
The NHS advise the jabs for individuals with obesity-related medical conditions, alongside recommended lifestyle changes.
A number of clinicians say that, given the high risk of weight regain, the treatment might need to be long-term.
This opinion is echoed by drug manufacturers, who state that the findings "underscore the persistent nature of obesity," similar to managing diseases like diabetes.
User Accounts
People who have come off the medication explain a powerful resurgence of appetite.
"It felt as if a switch flipping and I was suddenly extremely hungry," recalled one woman.
This difficulty is compounded if users have not developed permanent dietary or behavioural changes during therapy.
Widespread Adoption
Survey data indicate that millions of people in the UK have used weight-loss jabs in the past year, with interest remaining high.
- Adoption is higher among women than men.
- The middle-aged demographic shows the greatest usage rates.
- Many access the drugs through private prescriptions rather than the NHS.
In conclusion, researchers caution that while the jabs are powerful agents for shedding pounds, they are not a permanent cure and long-term success hinges on integrated lifestyle support.
