Fresh analysis indicates that individuals who come off popular slimming jabs like semaglutide or tirzepatide tend to recover lost weight much more quickly than those who end traditional diet and exercise plans.
Findings released in a major health publication shows that while obese people often shed substantial amounts of their total mass while on the medication, the mass comes back at an estimated rate of nearly a kilo each month once they quit.
"Individuals buying these medications should be informed of the potential of quick rebound weight gain when the therapy concludes," warns expert Dr. Susan Jebb.
Such speed of regain implies a return to starting weight within about a year and a half.
Weighing Approaches
The research, which reviewed dozens of trials involving over 9,000 of patients, contrasted the outcomes of the injectable medications with conventional dieting.
Scientists note that people who shed pounds through lifestyle changes alone typically experience a slower creep back—around 0.1 kg a month—post-intervention.
The Reason for the Quick Rebound
Doctors suggest the mode of action of the jabs accounts for the amplified weight return.
These medications copy a body's own chemical called GLP-1, which moderates hunger.
"Long-term administration of GLP-1 levels far above than the body's typical production may cause the system to generate a reduced amount of its own natural hormone, and may also lessen sensitivity to its actions," said Dr. Adam Collins, a nutrition researcher.
"Stopping of this hormone supplement results in hunger is no longer kept in check, making overeating a significant risk."
A Chronic Condition?
The NHS suggest the injections for individuals with weight-linked health risks, alongside prescribed diet and exercise modifications.
A number of clinicians argue that, due to the significant potential of weight regain, the treatment might need to be life-long.
This view is supported by pharmaceutical companies, who note that the findings "highlight the chronic character of obesity," similar to managing diseases like high blood pressure.
User Testimonies
Individuals who have stopped the jabs report a powerful return of hunger.
"I experienced something flipping and you become starving," described a patient.
This difficulty is compounded if patients have not adopted permanent lifestyle or habit changes during therapy.
Significant Interest
Figures indicate that millions of people in the UK have used these injections in the last 12 months, with desire being substantial.
- Adoption is higher among females than males.
- The middle-aged age group shows the greatest level of interest.
- Many access the drugs through private prescriptions rather than the NHS.
Ultimately, clinicians emphasize that while these medications are powerful tools for weight loss, they are not a permanent fix and long-term success likely depends on ongoing lifestyle management.
