Fresh analysis suggests that patients who stop using blockbuster slimming jabs like semaglutide or tirzepatide may regain shed pounds far faster than those who halt conventional diet and exercise programs.
Findings released in a prominent medical journal shows that while obese individuals frequently drop substantial amounts of their body weight while on the medication, the weight returns at an average rate of nearly a kilo each month once they quit.
"Users purchasing these medications must be cognizant of the potential of rapid rebound weight gain when the treatment is stopped," stated expert Dr. Susan Jebb.
Such speed of recovery implies a return to pre-treatment weight in about a year and a half.
Weighing Treatments
The analysis, which reviewed 37 of trials involving thousands of patients, contrasted the outcomes of GLP-1 agonists with older methods.
The team emphasize that people who lose weight through diet and exercise generally experience a more gradual weight regain—perhaps 0.1 kg a month—once they finish.
Explaining the Fast Rebound
Nutrition scientists propose the way of the injections is key to understanding the accelerated rebound.
These medications copy a body's own chemical called glucagon-like peptide-1, which controls hunger.
"Long-term administration of the hormone concentrations far above than the body's typical production may cause the system to generate a reduced amount of its own natural GLP-1, and could reduce sensitivity to its actions," said Dr. Adam Collins, a nutrition researcher.
"Stopping of this hormone supplement results in hunger is no longer kept in check, making excessive eating much more probable."
A Lifelong Disease?
The NHS advise the injections for people with weight-linked medical conditions, accompanied by prescribed diet and exercise modifications.
Many experts contend that, given the likelihood of weight regain, the treatment should be considered ongoing.
This view is reinforced by drug manufacturers, who note that the results "highlight the persistent nature of obesity," akin to managing conditions like diabetes.
User Accounts
People who have discontinued the medication report a intense resurgence of cravings.
"I experienced a trigger flipping and I was suddenly starving," said a patient.
This difficulty is exacerbated if patients have not developed sustainable lifestyle or habit changes during therapy.
Growing Interest
Survey data indicate that millions of adults in the UK have tried these injections in the past year, with demand remaining high.
- Use is higher among women than males.
- The 40s and 50s age group shows the greatest usage rates.
- A large proportion obtain the medications through private prescriptions rather than public health services.
In conclusion, clinicians stress that while the jabs are powerful agents for shedding pounds, they are not a standalone fix and long-term success likely depends on ongoing lifestyle changes.
