A recent study suggests that patients who discontinue new weight-loss injections like semaglutide or tirzepatide tend to recover shed pounds far faster than those who stop conventional lifestyle programs.
Research printed in a leading medical journal shows that while obese people often shed about a fifth of their total mass while on the medication, the weight returns at an average rate of 0.8 kg per month once they quit.
"Individuals using these medications should be informed of the danger of fast weight regain when the treatment is stopped," stated lead investigator Dr. Susan Jebb.
Such speed of recovery implies a return to original mass within about 18 months.
Weighing Therapies
The research, which reviewed 37 of trials involving over 9,000 of patients, contrasted the outcomes of the injectable medications with conventional dieting.
Scientists note that people who shed pounds through dieting generally experience a less rapid weight regain—approximately 0.1 kg a month—post-intervention.
Explaining the Fast Rebound
Experts believe the mechanism of the drugs is key to understanding the amplified regain.
These medications mimic a natural hormone called glucagon-like peptide-1, which moderates hunger.
"Artificially providing GLP-1 levels far above than the body's typical production may cause the system to generate a reduced amount of its own natural GLP-1, and may also diminish responsiveness to its actions," explained Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this GLP-1 'fix' results in appetite is no longer kept in check, making excessive eating a significant risk."
An Ongoing Condition?
Medical guidelines recommend the injections for individuals with weight-linked health risks, alongside recommended diet and exercise modifications.
Many experts contend that, given the high risk of weight regain, the treatment should be considered life-long.
This opinion is echoed by drug manufacturers, who say that the results "highlight the long-term nature of excess weight," similar to managing conditions like high blood pressure.
Patient Experiences
Users who have come off the jabs report a intense return of hunger.
"It felt as if a switch flipping and you're instantly ravenous," described a patient.
This difficulty is exacerbated if patients have not adopted lasting dietary or behavioural changes during treatment.
Significant Use
Figures show that a significant number of adults in the UK have used these injections in the last 12 months, with demand continuing to grow.
- Use is more common among females compared to males.
- The middle-aged demographic shows the highest usage rates.
- Many access the drugs through private healthcare rather than public health services.
In conclusion, clinicians caution that while the jabs are effective tools for shedding pounds, they are not a permanent cure and lasting health benefits likely depends on combined lifestyle management.
