A recent study indicates that individuals who stop using popular GLP-1 drugs like semaglutide or tirzepatide tend to recover shed pounds much more quickly than those who stop conventional diet and exercise regimens.
Published data in a major medical journal points out that while obese people frequently drop a large proportion of their total mass while undergoing treatment, the weight is regained at an average rate of 0.8 kg per month once they quit.
"Users using such drugs should be aware of the risk of rapid weight regain when the treatment is stopped," stated lead investigator Dr. Susan Jebb.
Such speed of regain implies a return to pre-treatment weight within about a year and a half.
Weighing Approaches
The research, which looked at dozens of trials involving thousands of patients, contrasted the outcomes of GLP-1 agonists with other pills.
The team note that people who lose weight through dieting usually experience a slower creep back—approximately 100 grams monthly—post-intervention.
The Reason for the Fast Rebound
Nutrition scientists propose the way of the injections accounts for the amplified weight return.
These medications copy a body's own chemical called GLP-1, which controls hunger.
"Sustained high doses of GLP-1 levels several times higher than the body's typical production could lead to the system to produce less of its own natural GLP-1, and could reduce sensitivity to its actions," explained Dr. Adam Collins, a dietetics researcher.
"Discontinuation of this hormone supplement results in appetite is unsuppressed, making excessive eating a significant risk."
A Chronic Issue?
The NHS advise the injections for individuals with obesity-related medical conditions, alongside recommended lifestyle changes.
Many experts argue that, given the likelihood of relapse, the therapy might need to be ongoing.
This view is echoed by drug manufacturers, who note that the findings "highlight the chronic nature of obesity," comparing it to managing diseases like diabetes.
User Experiences
People who have discontinued the medication report a sudden resurgence of cravings.
"It felt as if a switch that goes on and you become starving," described one woman.
This challenge is worsened if patients have not developed sustainable lifestyle or habit modifications during treatment.
Growing Interest
Figures suggest that millions of people in the UK have tried weight-loss jabs in the past year, with desire being substantial.
- Adoption is greater among women compared to men.
- The middle-aged age group shows the greatest level of interest.
- Many obtain the medications through private prescriptions rather than the NHS.
In conclusion, clinicians caution that while the jabs are powerful agents for weight loss, they are not a magic solution and lasting health benefits relies on integrated lifestyle changes.
