Fresh analysis indicates that patients who stop using new GLP-1 drugs like Mounjaro or Wegovy tend to recover reduced body mass at a significantly accelerated pace than those who end traditional lifestyle plans.
Published data in a leading medical journal points out that while obese people often shed about a fifth of their total mass while using the jabs, the weight returns at an average rate of 0.8 kg per month upon discontinuation.
"People using such treatments should be cognizant of the danger of rapid weight regain when the treatment ends," warns researcher Dr. Susan Jebb.
That rate of regain means a return to starting weight in about a year and a half.
Comparing Approaches
The research, which looked at dozens of studies involving thousands of patients, compared the results of GLP-1 agonists with older methods.
Scientists point out that individuals who shed pounds through dieting typically experience a slower weight regain—approximately 0.1 kg a month—post-intervention.
The Reason for the Quick Regain
Experts propose the mechanism of the jabs is key to understanding the accelerated regain.
The injections imitate a body's own chemical called GLP-1, which controls feelings of fullness.
"Sustained high doses of the hormone concentrations several times higher than normal may cause the body to generate a reduced amount of its endogenous hormone, and could diminish sensitivity to its effects," said Dr. Adam Collins, a dietetics specialist.
"Withdrawal of this hormone supplement results in appetite is uncontrolled, making overeating far more likely."
An Ongoing Disease?
Health authorities recommend the injections for individuals with weight-linked medical conditions, alongside recommended lifestyle changes.
A number of clinicians argue that, considering the significant potential of relapse, the treatment is often long-term.
This perspective is reinforced by pharmaceutical companies, who say that the results "underscore the long-term character of obesity," similar to managing diseases like hypertension.
Patient Testimonies
People who have stopped the jabs describe a intense return of appetite.
"It was like something that goes on and I was suddenly ravenous," recalled one woman.
This challenge is worsened if individuals have not adopted permanent lifestyle or habit changes during treatment.
Widespread Interest
Recent estimates indicate that millions of people in the UK have tried these injections in the last 12 months, with desire being substantial.
- Adoption is higher among females than men.
- The middle-aged age group shows the greatest level of interest.
- Many access the medications through private prescriptions rather than the NHS.
In conclusion, researchers caution that while these medications are powerful agents for shedding pounds, they are not a magic cure and maintained weight loss likely depends on combined lifestyle management.
