New research reveals that patients who come off blockbuster slimming jabs like Wegovy and Mounjaro can put back on reduced body mass much more quickly than those who halt traditional diet and exercise regimens.
Published data in a leading medical journal demonstrates that while overweight individuals often shed substantial amounts of their total mass while using the jabs, the mass returns at an average rate of nearly a kilo each month upon discontinuation.
"Individuals purchasing these treatments should be aware of the potential of quick rebound weight gain when the treatment ends," cautioned researcher Dr. Susan Jebb.
Such speed of regain suggests a return to starting mass within about one and a half years.
Analyzing Approaches
The analysis, which reviewed dozens of studies involving thousands of participants, contrasted the outcomes of these new drugs with older methods.
The team note that people who lose weight through dieting typically experience a more gradual creep back—around 0.1 kg a month—post-intervention.
Explaining the Quick Rebound
Doctors believe the way of the injections accounts for the accelerated rebound.
The injections imitate a natural hormone called glucagon-like peptide-1, which moderates feelings of fullness.
"Artificially providing the hormone levels several times higher than the body's typical production may cause the system to generate a reduced amount of its own natural GLP-1, and may also diminish responsiveness to its effects," said Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this medication results in appetite is uncontrolled, making excessive eating far more likely."
A Lifelong Disease?
The NHS advise the injections for people with weight-linked medical conditions, accompanied by prescribed lifestyle changes.
Professionals argue that, considering the likelihood of relapse, the therapy might need to be ongoing.
This view is supported by pharmaceutical companies, who note that the results "highlight the long-term character of obesity," akin to managing diseases like high blood pressure.
Patient Accounts
Users who have stopped the jabs explain a intense resurgence of hunger.
"It felt as if a trigger activating and you're instantly extremely hungry," described one woman.
The struggle is exacerbated if users have not developed permanent dietary or behavioural modifications during treatment.
Widespread Adoption
Recent estimates indicate that millions of people in the UK have tried these injections in the last 12 months, with desire continuing to grow.
- Use is higher among women than males.
- The middle-aged age group shows the greatest level of interest.
- A large proportion obtain the drugs through private healthcare rather than public health services.
Ultimately, researchers stress that while the jabs are effective tools for weight loss, they are not a magic cure and long-term success likely depends on combined lifestyle changes.
