Fresh analysis indicates that people who discontinue blockbuster slimming jabs like Mounjaro or Wegovy can put back on lost weight at a significantly accelerated pace than those who stop conventional diet and exercise programs.
Published data in a leading health publication shows that while obese people can lose about a fifth of their body weight while using the jabs, the mass comes back at an estimated rate of 0.8 kg per month once they quit.
"People using these medications need to be aware of the potential of quick weight regain when the treatment is stopped," stated lead investigator Dr. Susan Jebb.
That rate of recovery means a return to original weight in about one and a half years.
Comparing Approaches
The research, which looked at dozens of studies involving thousands of participants, compared the outcomes of the injectable medications with conventional dieting.
Scientists note that people who shed pounds through lifestyle changes alone typically see a less rapid creep back—around 100 grams monthly—post-intervention.
Understanding the Fast Rebound
Experts believe the way of the drugs is key to understanding the heightened regain.
These medications mimic a natural hormone called GLP-1, which moderates appetite.
"Artificially providing the hormone levels several times higher than normal could lead to the body to produce less of its own natural hormone, and could reduce sensitivity to its effects," said Dr. Adam Collins, a nutrition researcher.
"Discontinuation of this GLP-1 'fix' leads to hunger is unsuppressed, making overeating much more probable."
A Lifelong Disease?
Health authorities recommend the jabs for individuals with weight-linked health risks, alongside prescribed lifestyle changes.
A number of clinicians contend that, given the likelihood of weight regain, the treatment is often ongoing.
This view is supported by drug manufacturers, who say that the results "emphasize the long-term character of excess weight," comparing it to managing diseases like diabetes.
User Accounts
Individuals who have discontinued the medication explain a intense resurgence of cravings.
"It felt as if a trigger activating and I was suddenly starving," recalled an individual.
The struggle is exacerbated if individuals have not adopted sustainable lifestyle or habit modifications during therapy.
Widespread Adoption
Figures show that millions of adults in the UK have used weight-loss jabs in the past year, with interest continuing to grow.
- Adoption is more common among females compared to men.
- The middle-aged demographic shows the highest level of interest.
- A large proportion obtain the drugs through private healthcare rather than public health services.
In conclusion, researchers emphasize that while the jabs are potent tools for shedding pounds, they are not a magic cure and long-term success likely depends on combined behavioural changes.
