Fresh analysis reveals that patients who discontinue blockbuster GLP-1 drugs like semaglutide or tirzepatide tend to recover shed pounds far faster than those who end traditional diet and exercise plans.
Findings released in a major health publication points out that while overweight individuals frequently drop substantial amounts of their total mass while on the medication, the mass comes back at an average rate of 0.8 kg per month upon discontinuation.
"Users using such treatments need to be cognizant of the danger of rapid rebound weight gain when the therapy is stopped," cautioned lead investigator Dr. Susan Jebb.
Such speed of recovery suggests a return to original weight within about one and a half years.
Comparing Treatments
The analysis, which looked at 37 of studies involving thousands of participants, compared the results of GLP-1 agonists with older methods.
The team point out that people who shed pounds through diet and exercise typically see a more gradual creep back—around 100 grams monthly—post-intervention.
Understanding the Fast Regain
Nutrition scientists suggest the mode of action of the drugs is key to understanding the accelerated regain.
The injections copy a natural hormone called GLP-1, which controls feelings of fullness.
"Artificially providing the hormone levels far above than normal could lead to the body to produce less of its own natural GLP-1, and may also diminish sensitivity to its effects," said Dr. Adam Collins, a nutrition researcher.
"Discontinuation of this medication means hunger is no longer kept in check, making binge eating far more likely."
A Chronic Issue?
Medical guidelines suggest the jabs for individuals with obesity-related medical conditions, alongside prescribed diet and exercise modifications.
Many experts say that, considering the likelihood of relapse, the therapy might need to be ongoing.
This opinion is reinforced by pharmaceutical companies, who state that the findings "highlight the persistent nature of excess weight," similar to managing conditions like high blood pressure.
User Experiences
Users who have discontinued the jabs describe a intense resurgence of hunger.
"It felt as if a switch flipping and you're instantly extremely hungry," described an individual.
The struggle is worsened if patients have not adopted permanent lifestyle or habit changes during therapy.
Growing Interest
Survey data suggest that millions of adults in the UK have used these injections in the last 12 months, with demand being substantial.
- Use is higher among women compared to men.
- The middle-aged demographic shows the highest level of interest.
- Many obtain the drugs through private healthcare rather than the NHS.
In conclusion, researchers emphasize that while the jabs are powerful tools for shedding pounds, they are not a magic cure and long-term success likely depends on integrated behavioural support.
