Fresh analysis indicates that patients who come off popular GLP-1 drugs like semaglutide or tirzepatide can put back on reduced body mass far faster than those who halt traditional diet and exercise regimens.
Published data in a major medical journal demonstrates that while overweight people often shed substantial amounts of their total mass while undergoing treatment, the weight is regained at an estimated rate of nearly a kilo each month after stopping.
"Users using these treatments should be cognizant of the potential of rapid weight regain when the therapy ends," stated researcher Dr. Susan Jebb.
This pace of recovery suggests a reversion to starting mass within about one and a half years.
Weighing Treatments
The analysis, which reviewed 37 of trials involving thousands of patients, compared the results of these new drugs with other pills.
Scientists point out that people who shed pounds through dieting generally have a less rapid creep back—approximately 0.1 kg a month—once they finish.
Explaining the Rapid Regain
Nutrition scientists suggest the mechanism of the drugs is key to understanding the amplified weight return.
The injections copy a natural hormone called GLP-1, which controls appetite.
"Sustained high doses of the hormone concentrations several times higher than the body's typical production might result in the system to produce less of its own natural hormone, and could diminish sensitivity to its effects," noted Dr. Adam Collins, a nutrition expert.
"Withdrawal of this medication leads to appetite is uncontrolled, making excessive eating a significant risk."
A Chronic Condition?
Health authorities recommend the jabs for people with obesity-related medical conditions, accompanied by recommended lifestyle changes.
A number of clinicians argue that, considering the high risk of relapse, the therapy is often ongoing.
This view is echoed by pharmaceutical companies, who state that the findings "underscore the persistent character of excess weight," akin to managing diseases like diabetes.
Patient Accounts
Users who have stopped the medication report a powerful return of appetite.
"It felt as if a trigger activating and I was suddenly starving," said a patient.
This challenge is worsened if patients have not established sustainable dietary or behavioural modifications during therapy.
Significant Interest
Recent estimates indicate that millions of people in the UK have tried weight-loss jabs in the last 12 months, with demand being substantial.
- Use is higher among women compared to males.
- The middle-aged demographic shows the greatest level of interest.
- Many obtain the drugs through private prescriptions rather than public health services.
Ultimately, experts caution that while these medications are effective agents for weight loss, they are not a permanent solution and long-term success relies on integrated behavioural changes.
