New research indicates that patients who come off new slimming jabs like semaglutide or tirzepatide may regain reduced body mass much more quickly than those who end conventional lifestyle regimens.
Findings released in a leading health publication shows that while obese people frequently drop substantial amounts of their total mass while on the medication, the weight comes back at an average rate of nearly a kilo each month once they quit.
"People buying such medications must be aware of the risk of quick rebound weight gain when the treatment ends," stated researcher Dr. Susan Jebb.
Such speed of recovery suggests a return to starting weight in about one and a half years.
Weighing Approaches
The study, which examined dozens of studies involving over 9,000 of patients, contrasted the outcomes of GLP-1 agonists with other pills.
Scientists point out that individuals who shed pounds through lifestyle changes alone typically have a less rapid weight regain—approximately 100 grams monthly—once they finish.
Explaining the Rapid Regain
Nutrition scientists suggest the way of the drugs accounts for the amplified regain.
These medications imitate a natural hormone called glucagon-like peptide-1, which moderates appetite.
"Long-term administration of GLP-1 levels several times higher than the body's typical production could lead to the body to produce less of its endogenous hormone, and may also diminish responsiveness to its effects," explained Dr. Adam Collins, a dietetics researcher.
"Discontinuation of this medication results in hunger is no longer kept in check, making binge eating far more likely."
An Ongoing Condition?
Health authorities suggest the jabs for individuals with weight-linked medical conditions, alongside prescribed lifestyle changes.
Professionals say that, considering the likelihood of weight regain, the therapy is often ongoing.
This opinion is echoed by drug manufacturers, who state that the findings "highlight the long-term nature of excess weight," similar to managing diseases like diabetes.
User Accounts
People who have discontinued the medication describe a intense resurgence of hunger.
"It felt as if a trigger flipping and you become starving," said a patient.
This difficulty is compounded if individuals have not developed permanent lifestyle or habit changes during therapy.
Growing Adoption
Survey data show that millions of adults in the UK have tried weight-loss jabs in the past year, with demand being substantial.
- Use is more common among women than men.
- The middle-aged demographic shows the greatest usage rates.
- Many access the drugs through private healthcare rather than public health services.
Finally, experts stress that while the jabs are effective agents for weight loss, they are not a permanent fix and lasting health benefits likely depends on ongoing behavioural management.
