A recent study indicates that individuals who come off popular weight-loss injections like semaglutide or tirzepatide may regain shed pounds far faster than those who halt traditional lifestyle programs.
Findings released in a major health publication shows that while overweight individuals frequently drop a large proportion of their total mass while using the jabs, the mass is regained at an average rate of 0.8 kg per month once they quit.
"Individuals buying such drugs need to be informed of the risk of fast weight regain when the treatment is stopped," stated lead investigator Dr. Susan Jebb.
This pace of regain means a reversion to pre-treatment weight in about 18 months.
Comparing Approaches
The study, which reviewed dozens of studies involving thousands of patients, compared the effects of GLP-1 agonists with other pills.
Scientists emphasize that individuals who shed pounds through dieting generally see a more gradual creep back—approximately 100 grams monthly—post-intervention.
The Reason for the Fast Rebound
Nutrition scientists propose the mechanism of the jabs explains the heightened regain.
The injections copy a natural hormone called GLP-1, which controls appetite.
"Artificially providing GLP-1 levels 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 responsiveness to its actions," explained Dr. Adam Collins, a dietetics expert.
"Discontinuation of this GLP-1 'fix' results in appetite is no longer kept in check, making excessive eating far more likely."
An Ongoing Disease?
Health authorities suggest the jabs for people with obesity-related health risks, accompanied by prescribed lifestyle changes.
Many experts contend that, given the significant potential of weight regain, the treatment might need to be life-long.
This perspective is reinforced by pharmaceutical companies, who state that the results "underscore the persistent character of excess weight," comparing it to managing diseases like high blood pressure.
Patient Experiences
People who have come off the jabs describe a sudden return of hunger.
"It felt as if a switch activating and I was suddenly ravenous," described one woman.
The struggle is worsened if patients have not adopted sustainable lifestyle or habit modifications during treatment.
Widespread Interest
Figures indicate that millions of adults in the UK have used these injections in the past year, with desire remaining high.
- Adoption is higher among women than males.
- The middle-aged age group shows the highest usage rates.
- Many access the drugs through private prescriptions rather than public health services.
In conclusion, researchers stress that while these medications are potent tools for shedding pounds, they are not a standalone solution and lasting health benefits likely depends on combined behavioural support.
