New research reveals that people who discontinue blockbuster GLP-1 drugs like semaglutide or tirzepatide tend to recover shed pounds at a significantly accelerated pace than those who halt conventional diet and exercise programs.
Research printed in a leading health publication demonstrates that while obese people often shed about a fifth of their body weight while using the jabs, the mass returns at an estimated rate of 0.8 kg per month once they quit.
"Users purchasing such medications need to be aware of the risk of rapid weight regain when the medication concludes," warns lead investigator Dr. Susan Jebb.
That rate of recovery means a return to original weight within about one and a half years.
Comparing Approaches
The analysis, which examined dozens of trials involving thousands of patients, contrasted the outcomes of the injectable medications with other pills.
Researchers emphasize that people who shed pounds through lifestyle changes alone generally experience a more gradual creep back—around 0.1 kg a month—once they finish.
The Reason for the Rapid Rebound
Doctors believe the mechanism of the injections accounts for the heightened rebound.
The injections copy a body's own chemical called GLP-1, which moderates feelings of fullness.
"Sustained high doses of GLP-1 levels several times higher than the body's typical production could lead to the body to produce less of its endogenous hormone, and could lessen responsiveness to its effects," noted Dr. Adam Collins, a dietetics specialist.
"Stopping of this hormone supplement leads to hunger is no longer kept in check, making overeating much more probable."
An Ongoing Issue?
Medical guidelines recommend the jabs for individuals with weight-linked medical conditions, alongside recommended lifestyle changes.
Professionals argue that, given the likelihood of weight regain, the treatment is often ongoing.
This opinion is echoed by pharmaceutical companies, who state that the findings "underscore the persistent character of obesity," similar to managing conditions like high blood pressure.
User Accounts
Individuals who have stopped the jabs report a powerful return of cravings.
"It felt as if something that goes on and you become extremely hungry," described a patient.
This challenge is compounded if patients have not adopted permanent dietary or behavioural changes during treatment.
Growing Use
Figures show that a significant number of people in the UK have tried weight-loss jabs in the last 12 months, with demand remaining high.
- Use is higher among females than males.
- The 40s and 50s demographic shows the highest usage rates.
- Many obtain the drugs through private prescriptions rather than the NHS.
In conclusion, researchers emphasize that while these medications are potent agents for shedding pounds, they are not a magic solution and lasting health benefits hinges on combined behavioural support.
