New research suggests that individuals who discontinue blockbuster GLP-1 drugs like Mounjaro or Wegovy tend to recover shed pounds much more quickly than those who end traditional diet and exercise regimens.
Findings released in a major health publication shows that while obese individuals often shed a large proportion of their total mass while using the jabs, the weight is regained at an estimated rate of 0.8 kg per month once they quit.
"Individuals purchasing these medications should be aware of the potential of quick rebound weight gain when the treatment ends," cautioned researcher Dr. Susan Jebb.
This pace of regain suggests a reversion to starting weight within about one and a half years.
Analyzing Therapies
The research, which examined 37 of studies involving thousands of participants, contrasted the effects of the injectable medications with conventional dieting.
Researchers point out that individuals who lose weight through lifestyle changes alone usually experience a more gradual weight regain—perhaps 0.1 kg a month—post-intervention.
Explaining the Quick Rebound
Experts believe the way of the jabs is key to understanding the accelerated rebound.
The injections imitate a body's own chemical called glucagon-like peptide-1, which helps regulate hunger.
"Long-term administration of the hormone levels several times higher than normal could lead to the body to generate a reduced amount of its endogenous hormone, and may also lessen sensitivity to its effects," said Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this medication results in hunger is unsuppressed, making excessive eating much more probable."
A Lifelong Disease?
Health authorities suggest the injections for people with weight-linked health risks, alongside prescribed lifestyle changes.
Professionals contend that, considering the significant potential of relapse, the therapy might need to be ongoing.
This perspective is supported by pharmaceutical companies, who say that the results "underscore the long-term nature of excess weight," similar to managing diseases like high blood pressure.
User Testimonies
Individuals who have come off the jabs describe a powerful resurgence of appetite.
"It was like a trigger activating and you're instantly starving," recalled an individual.
The struggle is compounded if individuals have not developed permanent dietary or behavioural changes during therapy.
Significant Interest
Figures show that millions of people in the UK have used weight-loss jabs in the last 12 months, with interest being substantial.
- Use is greater among females than men.
- The 40s and 50s demographic shows the greatest level of interest.
- A large proportion access the medications through private healthcare rather than the NHS.
In conclusion, researchers stress that while GLP-1 drugs are effective agents for shedding pounds, they are not a magic cure and maintained weight loss relies on combined lifestyle support.
