New research reveals that patients who come off blockbuster slimming jabs like semaglutide or tirzepatide can put back on shed pounds at a significantly accelerated pace than those who stop conventional lifestyle plans.
Published data in a prominent health publication shows that while obese individuals frequently drop about a fifth of their total mass while on the medication, the mass is regained at an estimated rate of 0.8 kg per month once they quit.
"People buying these medications should be informed of the danger of rapid rebound weight gain when the medication concludes," cautioned researcher Dr. Susan Jebb.
That rate of recovery implies a reversion to starting mass within about 18 months.
Analyzing Approaches
The analysis, which examined dozens of studies involving over 9,000 of participants, contrasted the results of these new drugs with conventional dieting.
Scientists note that people who lose weight through lifestyle changes alone typically have a slower weight regain—around 100 grams monthly—once they finish.
The Reason for the Rapid Rebound
Doctors believe the way of the injections accounts for the heightened weight return.
The injections imitate a natural hormone called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Artificially providing the hormone concentrations several times higher than the body's typical production might result in the body to produce less of its own natural hormone, and could diminish responsiveness to its effects," explained Dr. Adam Collins, a dietetics expert.
"Discontinuation of this GLP-1 'fix' means appetite is unsuppressed, making binge eating far more likely."
A Chronic Disease?
Medical guidelines recommend the injections for people with obesity-related health risks, alongside prescribed diet and exercise modifications.
Professionals say that, given the significant potential of weight regain, the therapy might need to be life-long.
This opinion is supported by pharmaceutical companies, who note that the results "highlight the long-term character of excess weight," similar to managing diseases like high blood pressure.
User Experiences
Users who have come off the jabs describe a intense return of cravings.
"I experienced a switch flipping and you're instantly extremely hungry," recalled a patient.
This difficulty is worsened if users have not adopted permanent lifestyle or habit changes during treatment.
Growing Adoption
Figures suggest that millions of people in the UK have tried weight-loss jabs in the last 12 months, with desire continuing to grow.
- Adoption is more common among women than males.
- The middle-aged age group shows the highest level of interest.
- Many obtain the medications through private healthcare rather than the NHS.
In conclusion, researchers stress that while GLP-1 drugs are powerful tools for weight loss, they are not a permanent cure and lasting health benefits hinges on combined lifestyle changes.
