Fresh analysis suggests that people who discontinue blockbuster GLP-1 drugs like semaglutide or tirzepatide tend to recover shed pounds far faster than those who halt conventional diet and exercise regimens.
Research printed in a prominent medical journal points out that while overweight people often shed a large proportion of their total mass while using the jabs, the mass comes back at an estimated rate of 0.8 kg per month upon discontinuation.
"People using these treatments must be informed of the risk of fast weight regain when the therapy ends," cautioned expert Dr. Susan Jebb.
That rate of regain suggests a reversion to original mass within about a year and a half.
Analyzing Treatments
The research, which reviewed dozens of trials involving thousands of patients, compared the effects of GLP-1 agonists with older methods.
Researchers emphasize that individuals who shed pounds through dieting generally experience a slower weight regain—perhaps 100 grams monthly—after stopping.
Understanding the Fast Regain
Doctors suggest the way of the injections explains the accelerated weight return.
The injections copy a body's own chemical called GLP-1, which helps regulate hunger.
"Artificially providing GLP-1 concentrations far above than normal could lead to the system to produce less of its endogenous GLP-1, and could diminish responsiveness to its effects," said Dr. Adam Collins, a nutrition expert.
"Stopping of this medication means hunger is no longer kept in check, making excessive eating far more likely."
A Lifelong Disease?
The NHS suggest the injections for people with obesity-related medical conditions, accompanied by prescribed diet and exercise modifications.
Professionals say that, considering the significant potential of relapse, the therapy is often long-term.
This perspective is supported by drug manufacturers, who note that the findings "highlight the long-term character of excess weight," comparing it to managing conditions like high blood pressure.
User Testimonies
Individuals who have come off the jabs report a sudden resurgence of cravings.
"I experienced a trigger that goes on and you're instantly starving," recalled a patient.
The struggle is compounded if patients have not adopted lasting lifestyle or habit changes during therapy.
Growing Interest
Recent estimates suggest that a significant number of adults in the UK have tried weight-loss jabs in the past year, with demand continuing to grow.
- Adoption is more common among women than males.
- The 40s and 50s demographic shows the highest usage rates.
- A large proportion obtain the medications through private prescriptions rather than the NHS.
In conclusion, researchers caution that while these medications are powerful agents for weight loss, they are not a standalone cure and long-term success relies on combined lifestyle management.
