Fresh analysis suggests that individuals who stop using new weight-loss injections like semaglutide or tirzepatide may regain shed pounds at a significantly accelerated pace than those who stop traditional lifestyle programs.
Findings released in a prominent medical journal points out that while overweight people frequently drop a large proportion of their total mass while on the medication, the weight returns at an average rate of nearly a kilo each month upon discontinuation.
"People purchasing such drugs should be aware of the risk of quick rebound weight gain when the medication concludes," stated lead investigator Dr. Susan Jebb.
This pace of recovery suggests a return to starting mass within about 18 months.
Weighing Therapies
The research, which reviewed 37 of studies involving thousands of patients, compared the effects of these new drugs with conventional dieting.
Scientists point out that people who lose weight through diet and exercise typically see a more gradual weight regain—approximately 100 grams monthly—after stopping.
Understanding the Quick Rebound
Doctors propose the mechanism of the jabs accounts for the accelerated rebound.
The injections copy a natural hormone called GLP-1, which helps regulate feelings of fullness.
"Long-term administration of GLP-1 concentrations far above than normal could lead to the body to produce less of its own natural hormone, and could lessen sensitivity to its actions," noted Dr. Adam Collins, a dietetics expert.
"Discontinuation of this medication means appetite is uncontrolled, making binge eating far more likely."
An Ongoing Disease?
Medical guidelines advise the injections for people with weight-linked health risks, accompanied by recommended diet and exercise modifications.
Many experts contend that, given the likelihood of relapse, the treatment should be considered life-long.
This opinion is supported by drug manufacturers, who note that the results "highlight the long-term character of excess weight," comparing it to managing conditions like hypertension.
Patient Accounts
People who have come off the medication report a intense resurgence of cravings.
"It felt as if something that goes on and I was suddenly starving," said one woman.
The struggle is compounded if patients have not established lasting lifestyle or habit changes during treatment.
Growing Use
Recent estimates show that millions of adults in the UK have used these injections in the past year, with desire continuing to grow.
- Use is more common among women than males.
- The middle-aged demographic shows the highest level of interest.
- Many access the drugs through private prescriptions rather than public health services.
In conclusion, clinicians emphasize that while the jabs are powerful agents for shedding pounds, they are not a standalone solution and lasting health benefits hinges on integrated behavioural changes.
