Fresh analysis suggests that people who discontinue new GLP-1 drugs like semaglutide or tirzepatide tend to recover lost weight much more quickly than those who halt conventional diet and exercise programs.
Research printed in a major medical journal demonstrates that while overweight people can lose substantial amounts of their total mass while using the jabs, the weight comes back at an estimated rate of nearly a kilo each month upon discontinuation.
"Individuals purchasing these drugs need to be informed of the potential of quick rebound weight gain when the treatment ends," cautioned researcher Dr. Susan Jebb.
That rate of regain suggests a return to starting mass in about one and a half years.
Analyzing Approaches
The analysis, which examined 37 of trials involving over 9,000 of patients, contrasted the results of GLP-1 agonists with older methods.
Scientists note that people who shed pounds through lifestyle changes alone usually experience a more gradual creep back—around 0.1 kg a month—post-intervention.
Understanding the Rapid Regain
Doctors suggest the mode of action of the drugs is key to understanding the accelerated rebound.
The injections imitate a natural hormone called GLP-1, which helps regulate feelings of fullness.
"Artificially providing the hormone levels several times higher than normal may cause the body to generate a reduced amount of its own natural GLP-1, and may also reduce responsiveness to its actions," noted Dr. Adam Collins, a dietetics specialist.
"Stopping of this hormone supplement means hunger is unsuppressed, making binge eating a significant risk."
An Ongoing Issue?
The NHS recommend the injections for people with weight-linked health risks, alongside prescribed lifestyle changes.
A number of clinicians contend that, considering the high risk of weight regain, the therapy might need to be ongoing.
This view is supported by pharmaceutical companies, who say that the findings "emphasize the persistent character of excess weight," akin to managing conditions like diabetes.
Patient Accounts
People who have discontinued the jabs describe a powerful return of hunger.
"I experienced something flipping and I was suddenly starving," recalled a patient.
This challenge is exacerbated if patients have not adopted sustainable lifestyle or habit modifications during treatment.
Significant Interest
Figures indicate that millions of people in the UK have used weight-loss jabs in the past year, with interest continuing to grow.
- Use is greater among women compared to males.
- The middle-aged age group shows the highest level of interest.
- A large proportion access the drugs through private healthcare rather than public health services.
In conclusion, experts stress that while the jabs are effective tools for shedding pounds, they are not a magic solution and lasting health benefits likely depends on ongoing behavioural support.
