New research reveals that people who come off new weight-loss injections like semaglutide or tirzepatide can put back on shed pounds at a significantly accelerated pace than those who stop traditional lifestyle regimens.
Published data in a prominent health publication shows that while overweight individuals often shed substantial amounts of their total mass while on the medication, the weight returns at an estimated rate of nearly a kilo each month after stopping.
"Users buying these medications should be aware of the danger of quick rebound weight gain when the treatment ends," warns researcher Dr. Susan Jebb.
Such speed of regain implies a reversion to original mass in about a year and a half.
Weighing Therapies
The analysis, which examined dozens of trials involving thousands of patients, contrasted the effects of these new drugs with older methods.
Scientists point out that individuals who lose weight through lifestyle changes alone generally experience a less rapid weight regain—approximately 100 grams monthly—once they finish.
The Reason for the Fast Rebound
Experts suggest the way of the injections is key to understanding the accelerated weight return.
These medications mimic a natural hormone called GLP-1, which helps regulate appetite.
"Long-term administration of the hormone levels far above than the body's typical production might result in the system to produce less of its endogenous GLP-1, and may also lessen sensitivity to its actions," explained Dr. Adam Collins, a nutrition specialist.
"Discontinuation of this medication leads to hunger is no longer kept in check, making binge eating far more likely."
A Chronic Disease?
Health authorities suggest the injections for people with obesity-related medical conditions, alongside recommended lifestyle changes.
Many experts contend that, considering the significant potential of relapse, the treatment might need to be ongoing.
This opinion is echoed by pharmaceutical companies, who say that the findings "underscore the chronic nature of obesity," comparing it to managing diseases like high blood pressure.
User Testimonies
Individuals who have stopped the medication explain a sudden return of hunger.
"It felt as if a switch activating and you're instantly extremely hungry," recalled one woman.
The struggle is exacerbated if patients have not adopted lasting dietary or behavioural modifications during treatment.
Widespread Interest
Recent estimates show that millions of people in the UK have tried these injections in the last 12 months, with interest remaining high.
- Use is more common among females compared to males.
- The 40s and 50s age group shows the highest level of interest.
- Many access the medications through private healthcare rather than public health services.
Finally, clinicians caution that while the jabs are effective agents for shedding pounds, they are not a standalone solution and long-term success relies on combined lifestyle changes.
