A recent study reveals that patients who stop using blockbuster weight-loss injections like semaglutide or tirzepatide may regain reduced body mass far faster than those who stop conventional diet and exercise programs.
Published data in a major health publication points out that while obese people often shed 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.
"Users purchasing these drugs need to be aware of the risk of fast weight regain when the treatment is stopped," stated researcher Dr. Susan Jebb.
That rate of recovery means a return to pre-treatment weight in about one and a half years.
Analyzing Treatments
The study, which looked at dozens of trials involving over 9,000 of patients, compared the effects of the injectable medications with conventional dieting.
The team point out that people who lose weight through dieting generally experience a less rapid weight regain—perhaps 0.1 kg a month—post-intervention.
Explaining the Rapid Rebound
Doctors believe the way of the injections accounts for the amplified rebound.
These medications mimic a natural hormone called GLP-1, which moderates appetite.
"Artificially providing the hormone levels far above than the body's typical production could lead to the system to generate a reduced amount of its own natural GLP-1, and could diminish responsiveness to its actions," explained Dr. Adam Collins, a dietetics expert.
"Withdrawal of this GLP-1 'fix' means appetite is no longer kept in check, making overeating much more probable."
A Lifelong Disease?
The NHS advise the injections for individuals with weight-linked health risks, alongside recommended diet and exercise modifications.
Many experts say that, considering the high risk of weight regain, the therapy is often ongoing.
This opinion is echoed by drug manufacturers, who note that the findings "highlight the chronic nature of obesity," akin to managing diseases like diabetes.
Patient Accounts
People who have come off the jabs explain a powerful resurgence of hunger.
"It felt as if a switch flipping and you're instantly starving," described a patient.
This difficulty is worsened if users have not developed sustainable lifestyle or habit changes during therapy.
Growing Use
Figures suggest that millions of adults in the UK have tried these injections in the last 12 months, with interest continuing to grow.
- Adoption is higher among females than men.
- The 40s and 50s demographic shows the greatest usage rates.
- Many obtain the medications through private healthcare rather than public health services.
In conclusion, clinicians emphasize that while the jabs are effective tools for shedding pounds, they are not a magic cure and maintained weight loss likely depends on integrated lifestyle support.
