A recent study suggests that individuals who stop using popular slimming jabs like semaglutide or tirzepatide may regain lost weight much more quickly than those who halt traditional lifestyle programs.
Published data in a major health publication demonstrates that while overweight individuals often shed substantial amounts of their total mass while undergoing treatment, the mass is regained at an estimated rate of 0.8 kg per month after stopping.
"People buying these medications must be cognizant of the risk of fast rebound weight gain when the medication concludes," stated lead investigator Dr. Susan Jebb.
That rate of recovery suggests a return to pre-treatment mass within about one and a half years.
Weighing Treatments
The analysis, which reviewed dozens of studies involving over 9,000 of patients, compared the effects of these new drugs with older methods.
Scientists note that individuals who shed pounds through dieting typically see a more gradual creep back—around 100 grams monthly—after stopping.
The Reason for the Quick Regain
Experts believe the mode of action of the injections explains the heightened rebound.
These medications copy a body's own chemical called GLP-1, which controls appetite.
"Long-term administration of the hormone levels several times higher than the body's typical production might result in the body to produce less of its endogenous GLP-1, and may also diminish sensitivity to its effects," explained Dr. Adam Collins, a nutrition expert.
"Discontinuation of this GLP-1 'fix' results in hunger is unsuppressed, making excessive eating much more probable."
A Chronic Condition?
Medical guidelines suggest the injections for individuals with weight-linked health risks, alongside prescribed diet and exercise modifications.
A number of clinicians contend that, considering the high risk of relapse, the treatment might need to be life-long.
This opinion is echoed by pharmaceutical companies, who state that the findings "emphasize the chronic character of obesity," similar to managing diseases like diabetes.
User Accounts
People who have stopped the jabs describe a sudden resurgence of cravings.
"It felt as if a switch that goes on and you're instantly extremely hungry," recalled one woman.
This difficulty is exacerbated if individuals have not established lasting lifestyle or habit changes during treatment.
Significant Use
Recent estimates show that millions of adults in the UK have used weight-loss jabs in the last 12 months, with interest continuing to grow.
- Use is greater among women than males.
- The 40s and 50s age group shows the greatest level of interest.
- A large proportion obtain the drugs through private prescriptions rather than the NHS.
Finally, researchers emphasize that while the jabs are powerful agents for weight loss, they are not a permanent cure and maintained weight loss relies on integrated lifestyle support.
