A recent study reveals that people who come off blockbuster weight-loss injections like semaglutide or tirzepatide may regain lost weight much more quickly than those who stop traditional lifestyle regimens.
Findings released in a prominent health publication demonstrates that while overweight people frequently drop substantial amounts of their body weight while undergoing treatment, the weight returns at an average rate of 0.8 kg per month after stopping.
"People using such treatments need to be cognizant of the danger of rapid rebound weight gain when the medication is stopped," warns expert Dr. Susan Jebb.
That rate of recovery means a reversion to original mass within about 18 months.
Weighing Therapies
The study, which looked at 37 of trials involving thousands of participants, compared the results of the injectable medications with older methods.
Scientists point out that people who lose weight through dieting generally experience a more gradual weight regain—around 0.1 kg a month—once they finish.
Explaining the Fast Rebound
Doctors believe the mode of action of the jabs is key to understanding the amplified regain.
The injections mimic a natural hormone called glucagon-like peptide-1, which controls hunger.
"Sustained high doses of GLP-1 concentrations several times higher than the body's typical production might result in the system to produce less of its own natural GLP-1, and may also reduce responsiveness to its actions," said Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this medication means appetite is no longer kept in check, making binge eating far more likely."
An Ongoing Condition?
Health authorities suggest the jabs for people with obesity-related medical conditions, alongside recommended lifestyle changes.
A number of clinicians say that, due to the high risk of weight regain, the treatment is often life-long.
This opinion is echoed by pharmaceutical companies, who say that the results "emphasize the chronic nature of excess weight," similar to managing conditions like diabetes.
User Testimonies
People who have come off the medication report a sudden resurgence of appetite.
"It was like a switch activating and you're instantly ravenous," recalled one woman.
This difficulty is exacerbated if users have not developed permanent dietary or behavioural modifications during treatment.
Growing Use
Survey data suggest that a significant number of people in the UK have tried weight-loss jabs in the last 12 months, with interest continuing to grow.
- Adoption is higher among women compared to men.
- The middle-aged demographic shows the highest level of interest.
- A large proportion obtain the drugs through private prescriptions rather than public health services.
In conclusion, experts stress that while these medications are effective tools for weight loss, they are not a permanent solution and long-term success likely depends on ongoing lifestyle support.
