A recent study reveals that individuals who come off popular slimming jabs like semaglutide or tirzepatide can put back on shed pounds far faster than those who halt conventional diet and exercise regimens.
Research printed in a leading health publication points out that while obese individuals can lose substantial amounts of their body weight while undergoing treatment, the mass is regained at an estimated rate of nearly a kilo each month after stopping.
"People purchasing such drugs need to be cognizant of the risk of quick weight regain when the therapy ends," warns researcher Dr. Susan Jebb.
That rate of recovery suggests a reversion to starting weight in about one and a half years.
Weighing Approaches
The research, which reviewed dozens of trials involving over 9,000 of participants, contrasted the outcomes of these new drugs with older methods.
Scientists emphasize that people who lose weight through lifestyle changes alone typically have a less rapid weight regain—perhaps 100 grams monthly—post-intervention.
Understanding the Quick Rebound
Nutrition scientists propose the mode of action of the jabs accounts for the amplified regain.
The injections mimic a body's own chemical called GLP-1, which controls appetite.
"Long-term administration of the hormone levels far above than the body's typical production could lead to the system to produce less of its endogenous hormone, and may also diminish sensitivity to its actions," said Dr. Adam Collins, a nutrition expert.
"Stopping of this medication leads to appetite is unsuppressed, making overeating a significant risk."
A Chronic Condition?
Medical guidelines recommend the injections for individuals with obesity-related health risks, alongside prescribed lifestyle changes.
Many experts contend that, due to the high risk of weight regain, the therapy might need to be life-long.
This perspective is supported by pharmaceutical companies, who say that the results "highlight the long-term character of obesity," akin to managing diseases like diabetes.
Patient Accounts
Individuals who have stopped the jabs explain a powerful resurgence of cravings.
"It was like something that goes on and I was suddenly starving," recalled one woman.
The struggle is compounded if patients have not developed sustainable lifestyle or habit changes during therapy.
Growing Use
Survey data indicate that millions of adults in the UK have used these injections in the last 12 months, with demand remaining high.
- Use is higher among women compared to men.
- The 40s and 50s demographic shows the highest level of interest.
- Many access the drugs through private prescriptions rather than the NHS.
Ultimately, clinicians stress that while the jabs are potent agents for weight loss, they are not a magic solution and long-term success likely depends on integrated lifestyle management.
