Fresh analysis reveals that patients who stop using popular GLP-1 drugs like Mounjaro or Wegovy may regain shed pounds much more quickly than those who halt conventional lifestyle regimens.
Published data in a leading health publication shows that while overweight people often shed substantial amounts of their body weight while on the medication, the weight is regained at an average rate of nearly a kilo each month once they quit.
"People purchasing such treatments should be cognizant of the potential of fast rebound weight gain when the therapy ends," stated researcher Dr. Susan Jebb.
Such speed of regain suggests a reversion to starting weight in about 18 months.
Comparing Therapies
The study, which looked at dozens of trials involving over 9,000 of participants, contrasted the effects of GLP-1 agonists with older methods.
Researchers point out that individuals who shed pounds through lifestyle changes alone generally see a less rapid weight regain—around 100 grams monthly—once they finish.
Understanding the Rapid Rebound
Nutrition scientists believe the mode of action of the jabs accounts for the heightened weight return.
GLP-1 drugs copy a body's own chemical called glucagon-like peptide-1, which controls appetite.
"Sustained high doses of the hormone concentrations several times higher than the body's typical production may cause the body to generate a reduced amount of its own natural hormone, and could lessen responsiveness to its effects," noted Dr. Adam Collins, a dietetics specialist.
"Discontinuation of this hormone supplement leads to appetite is uncontrolled, making binge eating much more probable."
A Lifelong Disease?
Medical guidelines advise the injections for individuals with obesity-related health risks, accompanied by recommended lifestyle changes.
Professionals say that, due to the significant potential of weight regain, the treatment should be considered ongoing.
This opinion is echoed by drug manufacturers, who state that the findings "emphasize the chronic character of obesity," akin to managing diseases like diabetes.
Patient Testimonies
Users who have stopped the medication explain a sudden return of appetite.
"It was like something flipping and you're instantly ravenous," said a patient.
The struggle is worsened if individuals have not adopted lasting lifestyle or habit modifications during treatment.
Significant Interest
Recent estimates show that a significant number of people in the UK have tried these injections in the past year, with demand being substantial.
- Adoption is greater among women compared to males.
- The 40s and 50s demographic shows the highest level of interest.
- Many obtain the medications through private healthcare rather than the NHS.
In conclusion, researchers emphasize that while the jabs are potent agents for shedding pounds, they are not a permanent solution and long-term success hinges on combined behavioural management.
