Fresh analysis suggests that individuals who discontinue blockbuster slimming jabs like semaglutide or tirzepatide can put back on shed pounds far faster than those who end conventional lifestyle regimens.
Research printed in a major health publication points out that while overweight individuals often shed about a fifth of their total mass while on the medication, the mass is regained at an estimated rate of 0.8 kg per month after stopping.
"Individuals purchasing these medications need to be informed of the danger of rapid rebound weight gain when the therapy is stopped," stated researcher Dr. Susan Jebb.
This pace of recovery implies a reversion to original weight within about 18 months.
Comparing Approaches
The study, which reviewed dozens of trials involving over 9,000 of patients, compared the effects of these new drugs with conventional dieting.
Scientists point out that people who shed pounds through dieting usually experience a more gradual creep back—around 100 grams monthly—post-intervention.
Explaining the Quick Rebound
Experts suggest the mechanism of the jabs explains the accelerated rebound.
The injections mimic a natural hormone called GLP-1, which moderates appetite.
"Sustained high doses of GLP-1 levels far above than normal could lead to the system to produce less of its own natural GLP-1, and could lessen responsiveness to its actions," noted Dr. Adam Collins, a nutrition researcher.
"Discontinuation of this medication means hunger is uncontrolled, making overeating much more probable."
A Lifelong Condition?
The NHS suggest the injections for individuals with weight-linked health risks, accompanied by prescribed diet and exercise modifications.
A number of clinicians argue that, considering the high risk of weight regain, the treatment might need to be ongoing.
This opinion is reinforced by pharmaceutical companies, who state that the findings "underscore the chronic character of excess weight," comparing it to managing diseases like diabetes.
Patient Accounts
Individuals who have stopped the medication report a powerful return of hunger.
"It felt as if something flipping and you're instantly ravenous," recalled one woman.
This challenge is compounded if patients have not established lasting dietary or behavioural modifications during therapy.
Growing Interest
Recent estimates suggest that millions of people in the UK have tried these injections in the last 12 months, with interest remaining high.
- Adoption is greater among women compared to men.
- The middle-aged age group shows the greatest level of interest.
- A large proportion access the drugs through private healthcare rather than public health services.
In conclusion, clinicians caution that while these medications are effective agents for weight loss, they are not a magic cure and maintained weight loss relies on combined lifestyle management.
