New research reveals that people who stop using popular GLP-1 drugs like semaglutide or tirzepatide can put back on shed pounds at a significantly accelerated pace than those who stop traditional lifestyle programs.
Findings released in a prominent health publication shows that while obese people can lose about a fifth of their body weight while undergoing treatment, the mass returns at an average rate of nearly a kilo each month upon discontinuation.
"People buying such treatments must be cognizant of the danger of quick weight regain when the therapy concludes," cautioned expert Dr. Susan Jebb.
That rate of recovery suggests a reversion to pre-treatment mass within about one and a half years.
Weighing Approaches
The analysis, which examined 37 of studies involving over 9,000 of participants, contrasted the results of the injectable medications with other pills.
Researchers emphasize that people who lose weight through lifestyle changes alone generally see a slower creep back—around 100 grams monthly—once they finish.
Understanding the Quick Regain
Nutrition scientists believe the mode of action of the drugs accounts for the heightened weight return.
GLP-1 drugs copy a body's own chemical called glucagon-like peptide-1, which helps regulate hunger.
"Sustained high doses of GLP-1 concentrations several times higher than normal could lead to the body to generate a reduced amount of its endogenous hormone, and may also lessen sensitivity to its actions," said Dr. Adam Collins, a nutrition specialist.
"Discontinuation of this GLP-1 'fix' means hunger is uncontrolled, making binge eating much more probable."
A Lifelong Disease?
Health authorities suggest the jabs for individuals with weight-linked health risks, accompanied by recommended lifestyle changes.
A number of clinicians contend that, considering the significant potential of weight regain, the treatment might need to be long-term.
This view is supported by pharmaceutical companies, who say that the findings "highlight the chronic nature of obesity," akin to managing conditions like high blood pressure.
Patient Accounts
Users who have come off the medication describe a intense return of cravings.
"It was like something flipping and you're instantly extremely hungry," recalled one woman.
This difficulty is worsened if users have not developed permanent dietary or behavioural modifications during therapy.
Widespread Use
Survey data suggest that a significant number of people in the UK have used weight-loss jabs in the past year, with demand remaining high.
- Use is more common among women than men.
- The middle-aged age group shows the highest level of interest.
- Many access the medications through private healthcare rather than public health services.
In conclusion, experts stress that while the jabs are potent tools for weight loss, they are not a magic fix and lasting health benefits hinges on combined lifestyle management.
