A recent study suggests that people who stop using blockbuster weight-loss injections like Wegovy and Mounjaro can put back on reduced body mass at a significantly accelerated pace than those who stop traditional lifestyle programs.
Findings released in a major health publication points out that while overweight people often shed substantial amounts of their body weight while undergoing treatment, the weight is regained at an average rate of nearly a kilo each month once they quit.
"People buying these drugs should be aware of the danger of quick weight regain when the therapy concludes," stated lead investigator Dr. Susan Jebb.
This pace of recovery implies a return to starting weight within about one and a half years.
Analyzing Treatments
The study, which examined 37 of trials involving over 9,000 of participants, contrasted the effects of these new drugs with older methods.
Researchers point out that people who lose weight through dieting typically see a more gradual weight regain—perhaps 100 grams monthly—after stopping.
Explaining the Fast Rebound
Nutrition scientists propose the mechanism of the jabs accounts for the accelerated regain.
GLP-1 drugs copy a natural hormone called glucagon-like peptide-1, which controls feelings of fullness.
"Long-term administration of the hormone concentrations several times higher than normal could lead to the body to produce less of its own natural GLP-1, and may also reduce responsiveness to its actions," said Dr. Adam Collins, a nutrition specialist.
"Discontinuation of this medication means appetite is no longer kept in check, making binge eating a significant risk."
A Lifelong Issue?
Medical guidelines advise the jabs for people with weight-linked health risks, alongside recommended diet and exercise modifications.
Many experts argue that, due to the high risk of weight regain, the therapy might need to be long-term.
This perspective is echoed by pharmaceutical companies, who state that the results "underscore the chronic character of obesity," akin to managing diseases like hypertension.
User Testimonies
Individuals who have stopped the medication explain a powerful return of hunger.
"It was like something flipping and you're instantly ravenous," recalled one woman.
The struggle is worsened if users have not adopted permanent lifestyle or habit changes during treatment.
Significant Adoption
Recent estimates indicate that millions of people in the UK have used weight-loss jabs in the last 12 months, with interest continuing to grow.
- Use is higher among females compared to men.
- The middle-aged age group shows the greatest level of interest.
- Many obtain the medications through private prescriptions rather than public health services.
Ultimately, researchers caution that while the jabs are effective tools for shedding pounds, they are not a magic cure and lasting health benefits relies on integrated lifestyle support.
