A recent study suggests that patients who discontinue blockbuster GLP-1 drugs like semaglutide or tirzepatide can put back on lost weight far faster than those who halt traditional diet and exercise programs.
Published data in a major health publication points out that while overweight individuals frequently drop about a fifth of their total mass while using the jabs, the mass returns at an estimated rate of nearly a kilo each month upon discontinuation.
"Individuals purchasing these drugs must be cognizant of the danger of quick rebound weight gain when the therapy is stopped," stated lead investigator Dr. Susan Jebb.
Such speed of recovery suggests a return to pre-treatment mass within about a year and a half.
Analyzing Therapies
The research, which reviewed 37 of studies involving thousands of participants, contrasted the effects of GLP-1 agonists with conventional dieting.
Researchers point out that individuals who lose weight through diet and exercise typically see a more gradual weight regain—perhaps 100 grams monthly—after stopping.
The Reason for the Quick Regain
Nutrition scientists propose the mode of action of the drugs accounts for the accelerated regain.
The injections copy a body's own chemical called GLP-1, which helps regulate hunger.
"Artificially providing GLP-1 levels several times higher than normal could lead to the body to produce less of its endogenous GLP-1, and could lessen responsiveness to its actions," noted Dr. Adam Collins, a dietetics expert.
"Stopping of this hormone supplement results in appetite is uncontrolled, making excessive eating much more probable."
An Ongoing Issue?
The NHS recommend the jabs for people with obesity-related medical conditions, accompanied by prescribed diet and exercise modifications.
Many experts argue that, given the significant potential of relapse, the treatment might need to be long-term.
This view is echoed by drug manufacturers, who say that the results "emphasize the chronic character of obesity," comparing it to managing conditions like hypertension.
User Testimonies
Users who have discontinued the medication report a powerful return of hunger.
"It felt as if something that goes on and you become starving," said an individual.
The struggle is worsened if patients have not developed sustainable lifestyle or habit changes during treatment.
Growing Interest
Figures indicate that millions of people in the UK have tried weight-loss jabs in the past year, with interest remaining high.
- Use is higher among women compared to males.
- The 40s and 50s demographic shows the highest usage rates.
- A large proportion access the drugs through private healthcare rather than public health services.
Ultimately, researchers stress that while these medications are effective agents for shedding pounds, they are not a permanent fix and lasting health benefits hinges on integrated behavioural management.
