A recent study suggests that people who stop using blockbuster slimming jabs like semaglutide or tirzepatide may regain shed pounds at a significantly accelerated pace than those who halt traditional diet and exercise regimens.
Published data in a leading health publication demonstrates that while overweight people frequently drop a large proportion of their body weight while on the medication, the weight comes back at an estimated rate of nearly a kilo each month once they quit.
"Users buying these drugs must be cognizant of the risk of fast weight regain when the treatment ends," cautioned researcher Dr. Susan Jebb.
That rate of regain means a return to original mass in about a year and a half.
Comparing Treatments
The research, which reviewed 37 of studies involving thousands of patients, compared the effects of the injectable medications with older methods.
The team point out that people who shed pounds through dieting generally see a less rapid creep back—approximately 0.1 kg a month—post-intervention.
Understanding the Fast Rebound
Nutrition scientists suggest the way of the jabs accounts for the accelerated regain.
GLP-1 drugs imitate a body's own chemical called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Artificially providing GLP-1 levels far above than the body's typical production may cause the body to generate a reduced amount of its endogenous hormone, and could lessen sensitivity to its actions," explained Dr. Adam Collins, a nutrition expert.
"Discontinuation of this medication means appetite is no longer kept in check, making binge eating far more likely."
A Lifelong Issue?
Health authorities suggest the injections for people with weight-linked health risks, accompanied by recommended lifestyle changes.
Professionals argue that, considering the high risk of weight regain, the treatment should be considered life-long.
This opinion is supported by pharmaceutical companies, who state that the findings "emphasize the persistent character of excess weight," comparing it to managing conditions like high blood pressure.
Patient Experiences
People who have discontinued the jabs describe a powerful return of hunger.
"I experienced something activating and you become extremely hungry," described a patient.
The struggle is exacerbated if users have not established permanent lifestyle or habit changes during treatment.
Widespread Interest
Recent estimates show that a significant number of adults in the UK have used weight-loss jabs in the past year, with interest continuing to grow.
- Use is more common among women than males.
- The middle-aged age group shows the greatest level of interest.
- Many access the drugs through private healthcare rather than the NHS.
In conclusion, researchers emphasize that while GLP-1 drugs are effective agents for weight loss, they are not a magic solution and lasting health benefits likely depends on ongoing behavioural management.
