A recent study indicates that people who discontinue popular GLP-1 drugs like semaglutide or tirzepatide may regain reduced body mass much more quickly than those who stop traditional lifestyle regimens.
Research printed in a prominent health publication points out that while overweight people often shed a large proportion of their total mass while using the jabs, the mass comes back at an estimated rate of nearly a kilo each month once they quit.
"Users using these treatments need to be aware of the danger of quick rebound weight gain when the treatment is stopped," warns researcher Dr. Susan Jebb.
This pace of recovery implies a return to original mass within about 18 months.
Analyzing Therapies
The research, which examined 37 of trials involving thousands of patients, compared the effects of the injectable medications with older methods.
The team emphasize that individuals who lose weight through lifestyle changes alone typically have a slower creep back—perhaps 0.1 kg a month—once they finish.
Understanding the Quick Rebound
Nutrition scientists propose the mechanism of the jabs is key to understanding the heightened weight return.
GLP-1 drugs copy a natural hormone called GLP-1, which controls appetite.
"Artificially providing the hormone levels far above than the body's typical production may cause the system to generate a reduced amount of its endogenous hormone, and may also diminish sensitivity to its effects," explained Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this GLP-1 'fix' means hunger is unsuppressed, making overeating far more likely."
A Chronic Condition?
Medical guidelines recommend the jabs for people with obesity-related medical conditions, accompanied by prescribed diet and exercise modifications.
Many experts argue that, considering the likelihood of weight regain, the therapy should be considered life-long.
This opinion is supported by pharmaceutical companies, who state that the results "emphasize the persistent nature of obesity," comparing it to managing diseases like high blood pressure.
User Accounts
Users who have discontinued the medication explain a sudden return of appetite.
"It felt as if a trigger that goes on and you're instantly extremely hungry," said an individual.
The struggle is exacerbated if patients have not developed sustainable lifestyle or habit changes during treatment.
Significant Interest
Figures suggest that a significant number of adults in the UK have used weight-loss jabs in the past year, with demand remaining high.
- Use is more common among females than men.
- The 40s and 50s age group shows the highest usage rates.
- Many obtain the medications through private prescriptions rather than the NHS.
Ultimately, experts stress that while the jabs are effective tools for shedding pounds, they are not a standalone solution and maintained weight loss relies on integrated behavioural changes.
