A recent study indicates that patients who discontinue blockbuster slimming jabs like Wegovy and Mounjaro can put back on lost weight much more quickly than those who halt conventional diet and exercise plans.
Published data in a leading medical journal shows that while overweight people can lose substantial amounts of their body weight while using the jabs, the weight returns at an average rate of nearly a kilo each month once they quit.
"Users using these medications need to be aware of the potential of quick weight regain when the therapy is stopped," cautioned expert Dr. Susan Jebb.
This pace of regain means a return to original weight within about one and a half years.
Weighing Approaches
The analysis, which examined dozens of studies involving over 9,000 of participants, contrasted the effects of these new drugs with conventional dieting.
Scientists note that people who lose weight through dieting typically have a less rapid weight regain—perhaps 0.1 kg a month—once they finish.
Understanding the Quick Rebound
Doctors propose the mode of action of the injections accounts for the accelerated rebound.
These medications mimic a natural hormone called GLP-1, which controls appetite.
"Long-term administration of the hormone levels several times higher than normal may cause the system to generate a reduced amount of its endogenous hormone, and may also diminish sensitivity to its actions," explained Dr. Adam Collins, a dietetics researcher.
"Stopping of this GLP-1 'fix' results in hunger is uncontrolled, making binge eating far more likely."
An Ongoing Issue?
The NHS suggest the jabs for people with weight-linked health risks, accompanied by recommended lifestyle changes.
A number of clinicians say that, considering the likelihood of relapse, the treatment might need to be long-term.
This view is reinforced by pharmaceutical companies, who state that the results "underscore the chronic nature of excess weight," similar to managing conditions like hypertension.
User Testimonies
People who have come off the medication describe a intense resurgence of cravings.
"I experienced a trigger flipping and you're instantly extremely hungry," recalled an individual.
This challenge is worsened if individuals have not developed lasting dietary or behavioural modifications during treatment.
Widespread Adoption
Recent estimates show that millions of people in the UK have tried these injections in the past year, with demand continuing to grow.
- Use is more common among females compared to males.
- The middle-aged age group shows the greatest usage rates.
- Many access the drugs through private healthcare rather than public health services.
In conclusion, experts stress that while these medications are effective tools for weight loss, they are not a standalone solution and lasting health benefits relies on integrated behavioural support.
