New research indicates that patients who come off blockbuster GLP-1 drugs like semaglutide or tirzepatide may regain shed pounds far faster than those who halt traditional diet and exercise plans.
Research printed in a major health publication demonstrates that while overweight individuals often shed substantial amounts of their total mass while on the medication, the mass comes back at an average rate of 0.8 kg per month once they quit.
"Users using such medications need to be aware of the danger of rapid weight regain when the medication ends," warns researcher Dr. Susan Jebb.
This pace of regain suggests a reversion to pre-treatment mass in about one and a half years.
Analyzing Approaches
The research, which examined dozens of studies involving thousands of participants, contrasted the effects of the injectable medications with other pills.
Scientists emphasize that people who shed pounds through lifestyle changes alone usually see a less rapid creep back—around 0.1 kg a month—after stopping.
Explaining the Rapid Regain
Doctors suggest the mechanism of the injections accounts for the amplified regain.
The injections imitate a body's own chemical called glucagon-like peptide-1, which moderates hunger.
"Artificially providing the hormone levels far above than normal could lead to the body to generate a reduced amount of its own natural GLP-1, and may also lessen responsiveness to its actions," noted Dr. Adam Collins, a nutrition specialist.
"Stopping of this hormone supplement leads to hunger is no longer kept in check, making binge eating much more probable."
A Lifelong Condition?
The NHS recommend the injections for individuals with weight-linked health risks, accompanied by prescribed diet and exercise modifications.
A number of clinicians contend that, considering the likelihood of relapse, the therapy might need to be long-term.
This view is reinforced by pharmaceutical companies, who state that the findings "underscore the chronic character of excess weight," comparing it to managing conditions like high blood pressure.
Patient Testimonies
People who have stopped the medication explain a sudden return of appetite.
"It felt as if something that goes on and you become ravenous," described a patient.
This difficulty is exacerbated if users have not established permanent dietary or behavioural modifications during treatment.
Widespread Interest
Recent estimates show that a significant number of people in the UK have tried weight-loss jabs in the last 12 months, with desire continuing to grow.
- Adoption is higher among females compared to men.
- The 40s and 50s age group shows the greatest usage rates.
- Many access the drugs through private prescriptions rather than the NHS.
Ultimately, clinicians stress that while these medications are effective agents for shedding pounds, they are not a standalone solution and lasting health benefits hinges on ongoing lifestyle changes.
