A recent study suggests that individuals who come off new slimming jabs like semaglutide or tirzepatide can put back on shed pounds much more quickly than those who halt traditional diet and exercise programs.
Published data in a major health publication demonstrates that while overweight people frequently drop substantial amounts of their total mass while on the medication, the mass comes back at an estimated rate of 0.8 kg per month after stopping.
"People using such treatments should be informed of the danger of rapid rebound weight gain when the treatment ends," cautioned expert Dr. Susan Jebb.
This pace of recovery implies a return to pre-treatment weight within about a year and a half.
Weighing Treatments
The analysis, which looked at 37 of trials involving over 9,000 of participants, compared the outcomes of these new drugs with conventional dieting.
Scientists emphasize that individuals who lose weight through lifestyle changes alone usually experience a more gradual creep back—around 0.1 kg a month—post-intervention.
The Reason for the Rapid Rebound
Experts suggest the mode of action of the jabs is key to understanding the heightened rebound.
These medications imitate a body's own chemical called GLP-1, which helps regulate hunger.
"Sustained high doses of the hormone concentrations far above than the body's typical production may cause the body to generate a reduced amount of its own natural GLP-1, and may also lessen sensitivity to its effects," said Dr. Adam Collins, a nutrition expert.
"Discontinuation of this medication leads to hunger is uncontrolled, making binge eating much more probable."
A Lifelong Condition?
Health authorities recommend the jabs for people with obesity-related health risks, alongside recommended lifestyle changes.
A number of clinicians say that, considering the significant potential of relapse, the therapy should be considered long-term.
This opinion is echoed by drug manufacturers, who state that the results "emphasize the persistent nature of excess weight," similar to managing diseases like diabetes.
Patient Experiences
Individuals who have stopped the jabs explain a powerful resurgence of hunger.
"It felt as if a trigger that goes on and I was suddenly ravenous," recalled one woman.
This difficulty is worsened if users have not established permanent lifestyle or habit changes during treatment.
Significant Adoption
Figures suggest that a significant number of adults in the UK have tried weight-loss jabs in the last 12 months, with demand continuing to grow.
- Use is greater among females compared to males.
- The middle-aged demographic shows the greatest level of interest.
- A large proportion obtain the drugs through private healthcare rather than public health services.
Finally, researchers stress that while these medications are powerful agents for shedding pounds, they are not a magic fix and maintained weight loss likely depends on combined behavioural management.
