Fresh analysis indicates that patients who discontinue blockbuster weight-loss injections like semaglutide or tirzepatide can put back on shed pounds far faster than those who halt conventional lifestyle regimens.
Research printed in a prominent health publication points out that while overweight individuals often shed substantial amounts of their total mass while on the medication, the mass comes back at an estimated rate of 0.8 kg per month after stopping.
"Users buying these drugs need to be informed of the potential of fast rebound weight gain when the therapy is stopped," stated lead investigator Dr. Susan Jebb.
This pace of recovery suggests a return to pre-treatment weight within about a year and a half.
Analyzing Therapies
The research, which looked at 37 of trials involving over 9,000 of patients, compared the results of these new drugs with older methods.
The team emphasize that people who shed pounds through lifestyle changes alone typically see a more gradual creep back—around 0.1 kg a month—after stopping.
Understanding the Quick Rebound
Nutrition scientists propose the way of the jabs is key to understanding the amplified weight return.
These medications mimic a natural hormone called GLP-1, which helps regulate feelings of fullness.
"Long-term administration of GLP-1 levels several times higher than the body's typical production may cause the system to produce less of its endogenous hormone, and may also diminish responsiveness to its effects," noted Dr. Adam Collins, a nutrition expert.
"Withdrawal of this medication means appetite is uncontrolled, making excessive eating far more likely."
A Lifelong Condition?
The NHS advise the injections for individuals with obesity-related health risks, accompanied by prescribed lifestyle changes.
Professionals argue that, considering the high risk of relapse, the therapy might need to be long-term.
This opinion is echoed by drug manufacturers, who note that the results "emphasize the long-term character of obesity," similar to managing conditions like diabetes.
Patient Experiences
Users who have come off the medication report a sudden return of hunger.
"It felt as if a switch activating and I was suddenly extremely hungry," described one woman.
This difficulty is exacerbated if users have not established sustainable dietary or behavioural changes during treatment.
Widespread Adoption
Survey data show that a significant number of adults in the UK have used these injections in the past year, with desire remaining high.
- Use is higher among women compared to males.
- The middle-aged age group shows the highest level of interest.
- A large proportion obtain the drugs through private prescriptions rather than public health services.
In conclusion, researchers caution that while the jabs are effective tools for weight loss, they are not a magic fix and lasting health benefits relies on ongoing behavioural changes.
