A recent study suggests that people who come off blockbuster weight-loss injections like semaglutide or tirzepatide tend to recover shed pounds much more quickly than those who halt conventional diet and exercise regimens.
Findings released in a prominent medical journal points out that while obese people can lose substantial amounts of their total mass while undergoing treatment, the weight is regained at an estimated rate of nearly a kilo each month once they quit.
"People buying these drugs must be aware of the risk of quick rebound weight gain when the treatment concludes," warns lead investigator Dr. Susan Jebb.
This pace of recovery implies a return to starting mass within about a year and a half.
Comparing Therapies
The research, which looked at 37 of trials involving thousands of patients, contrasted the outcomes of GLP-1 agonists with conventional dieting.
Researchers note that individuals who lose weight through diet and exercise generally experience a slower weight regain—perhaps 0.1 kg a month—after stopping.
The Reason for the Fast Rebound
Doctors propose the mechanism of the drugs explains the amplified weight return.
GLP-1 drugs mimic a natural hormone called glucagon-like peptide-1, which moderates feelings of fullness.
"Sustained high doses of GLP-1 levels far above than normal might result in the body to produce less of its endogenous GLP-1, and could reduce responsiveness to its effects," explained Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this GLP-1 'fix' means appetite is no longer kept in check, making binge eating much more probable."
An Ongoing Issue?
The NHS advise the injections for individuals with weight-linked medical conditions, alongside recommended lifestyle changes.
Professionals argue that, considering the likelihood of relapse, the treatment should be considered long-term.
This perspective is supported by pharmaceutical companies, who state that the results "underscore the persistent character of obesity," akin to managing diseases like hypertension.
User Experiences
People who have come off the jabs describe a powerful return of appetite.
"I experienced something that goes on and I was suddenly ravenous," said a patient.
This difficulty is exacerbated if users have not developed lasting lifestyle or habit changes during therapy.
Significant Adoption
Figures indicate that a significant number of people in the UK have used these injections in the past year, with desire continuing to grow.
- Use is greater among women than men.
- The 40s and 50s age group shows the greatest level of interest.
- Many obtain the medications through private healthcare rather than the NHS.
In conclusion, researchers caution that while the jabs are powerful tools for shedding pounds, they are not a magic solution and lasting health benefits hinges on integrated behavioural support.
