A recent study suggests that patients who discontinue new slimming jabs like semaglutide or tirzepatide tend to recover shed pounds at a significantly accelerated pace than those who end conventional lifestyle regimens.
Published data in a prominent health publication demonstrates that while overweight individuals frequently drop 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 upon discontinuation.
"People using such medications should be cognizant of the potential of fast weight regain when the treatment concludes," cautioned expert Dr. Susan Jebb.
Such speed of regain implies a reversion to pre-treatment weight in about one and a half years.
Weighing Treatments
The analysis, which looked at dozens of studies involving thousands of participants, contrasted the effects of these new drugs with other pills.
Researchers note that individuals who shed pounds through dieting usually have a less rapid weight regain—approximately 100 grams monthly—post-intervention.
The Reason for the Rapid Regain
Nutrition scientists propose the mechanism of the drugs explains the accelerated regain.
These medications imitate a natural hormone called glucagon-like peptide-1, which helps regulate appetite.
"Sustained high doses of GLP-1 levels several times higher than the body's typical production might result in the system to produce less of its endogenous hormone, and could lessen sensitivity to its actions," explained Dr. Adam Collins, a dietetics expert.
"Stopping of this GLP-1 'fix' leads to appetite is uncontrolled, making binge eating far more likely."
A Lifelong Disease?
The NHS recommend the injections for individuals with obesity-related medical conditions, accompanied by prescribed diet and exercise modifications.
Professionals argue that, due to the significant potential of weight regain, the treatment is often long-term.
This view is echoed by drug manufacturers, who say that the results "highlight the chronic character of obesity," akin to managing diseases like diabetes.
User Experiences
Users who have stopped the jabs report a intense return of cravings.
"It was like a switch that goes on and you're instantly extremely hungry," described one woman.
The struggle is worsened if patients have not established sustainable lifestyle or habit changes during therapy.
Significant Interest
Survey data indicate that millions of people in the UK have used these injections in the past year, with interest remaining high.
- Use is more common among women than men.
- The middle-aged age group shows the greatest level of interest.
- A large proportion obtain the drugs through private healthcare rather than public health services.
Ultimately, experts emphasize that while the jabs are powerful agents for shedding pounds, they are not a magic fix and maintained weight loss likely depends on combined lifestyle management.
