New research indicates that individuals who stop using new slimming jabs like semaglutide or tirzepatide may regain lost weight at a significantly accelerated pace than those who end conventional lifestyle regimens.
Findings released in a prominent medical journal points out that while overweight individuals often shed about a fifth of their total mass while on the medication, the mass comes back at an estimated rate of nearly a kilo each month once they quit.
"People purchasing these drugs must be informed of the danger of quick weight regain when the treatment is stopped," warns expert Dr. Susan Jebb.
That rate of recovery suggests a reversion to starting weight within about one and a half years.
Analyzing Approaches
The analysis, which looked at 37 of studies involving over 9,000 of participants, contrasted the outcomes of the injectable medications with conventional dieting.
Researchers point out that people who lose weight through lifestyle changes alone usually experience a less rapid creep back—around 100 grams monthly—after stopping.
Explaining the Rapid Regain
Experts propose the mechanism of the drugs is key to understanding the amplified regain.
The injections copy a body's own chemical called GLP-1, which moderates hunger.
"Artificially providing GLP-1 concentrations several times higher than normal might result in the body to produce less of its endogenous GLP-1, and may also diminish sensitivity to its effects," noted Dr. Adam Collins, a dietetics researcher.
"Stopping of this medication leads to hunger is no longer kept in check, making excessive eating far more likely."
A Lifelong Condition?
The NHS advise the jabs for individuals with obesity-related health risks, alongside prescribed lifestyle changes.
Many experts argue that, considering the significant potential of relapse, the treatment might need to be long-term.
This opinion is echoed by pharmaceutical companies, who say that the findings "emphasize the long-term nature of excess weight," akin to managing diseases like diabetes.
User Accounts
People who have stopped the jabs report a powerful resurgence of hunger.
"I experienced something activating and I was suddenly ravenous," recalled an individual.
This challenge is exacerbated if patients have not established sustainable lifestyle or habit changes during treatment.
Growing Use
Recent estimates indicate that millions of people in the UK have tried these injections in the past year, with interest being substantial.
- Adoption is more common among women than males.
- The 40s and 50s demographic shows the highest level of interest.
- Many obtain the drugs through private healthcare rather than public health services.
Ultimately, researchers emphasize that while the jabs are effective tools for weight loss, they are not a magic cure and lasting health benefits hinges on combined behavioural support.
