A recent study suggests that patients who discontinue popular GLP-1 drugs like semaglutide or tirzepatide tend to recover reduced body mass at a significantly accelerated pace than those who end traditional lifestyle regimens.
Published data in a leading health publication shows that while overweight people can lose about a fifth of their total mass while on the medication, the weight is regained at an estimated rate of nearly a kilo each month after stopping.
"People purchasing such medications must be cognizant of the risk of rapid weight regain when the medication concludes," warns lead investigator Dr. Susan Jebb.
Such speed of recovery suggests a return to starting weight within about a year and a half.
Comparing Treatments
The study, which reviewed 37 of trials involving over 9,000 of participants, contrasted the effects of GLP-1 agonists with other pills.
The team point out that people who shed pounds through lifestyle changes alone generally see a less rapid creep back—approximately 100 grams monthly—once they finish.
The Reason for the Fast Rebound
Experts propose the mode of action of the drugs explains the amplified weight return.
GLP-1 drugs copy a body's own chemical called GLP-1, which moderates feelings of fullness.
"Sustained high doses of GLP-1 concentrations several times higher than the body's typical production may cause the system to generate a reduced amount of its endogenous GLP-1, and may also reduce sensitivity to its effects," explained Dr. Adam Collins, a dietetics specialist.
"Withdrawal of this GLP-1 'fix' results in appetite is no longer kept in check, making binge eating far more likely."
A Chronic Issue?
Health authorities advise the jabs for individuals with weight-linked medical conditions, accompanied by prescribed diet and exercise modifications.
A number of clinicians say that, considering the likelihood of weight regain, the treatment is often long-term.
This opinion is supported by pharmaceutical companies, who state that the results "underscore the persistent nature of obesity," similar to managing diseases like diabetes.
Patient Experiences
Users who have come off the medication describe a intense resurgence of hunger.
"It was like something flipping and you become extremely hungry," recalled a patient.
The struggle is worsened if users have not adopted sustainable lifestyle or habit changes during therapy.
Widespread Interest
Figures indicate that a significant number of people in the UK have used weight-loss jabs in the past year, with interest remaining high.
- Adoption is more common among females than males.
- The 40s and 50s age group shows the highest usage rates.
- A large proportion obtain the drugs through private prescriptions rather than public health services.
In conclusion, experts caution that while the jabs are potent tools for shedding pounds, they are not a magic fix and long-term success likely depends on ongoing behavioural management.
