Fresh analysis suggests that people who discontinue blockbuster slimming jabs like Wegovy and Mounjaro tend to recover shed pounds much more quickly than those who end traditional diet and exercise plans.
Published data in a leading medical journal points out that while obese people can lose a large proportion of their total mass while using the jabs, the mass comes back at an estimated rate of 0.8 kg per month upon discontinuation.
"Individuals buying such medications must be informed of the danger of rapid rebound weight gain when the medication ends," cautioned expert Dr. Susan Jebb.
Such speed of recovery implies a reversion to pre-treatment mass within about 18 months.
Analyzing Therapies
The analysis, which reviewed 37 of trials involving over 9,000 of patients, contrasted the outcomes of GLP-1 agonists with other pills.
Researchers emphasize that people who shed pounds through dieting typically experience a slower creep back—approximately 0.1 kg a month—once they finish.
Explaining the Fast Rebound
Doctors propose the mechanism of the drugs is key to understanding the accelerated rebound.
These medications copy a natural hormone called GLP-1, which moderates feelings of fullness.
"Long-term administration of GLP-1 concentrations far above than normal may cause the system to generate a reduced amount of its endogenous hormone, and may also diminish sensitivity to its effects," explained Dr. Adam Collins, a nutrition specialist.
"Discontinuation of this hormone supplement leads to hunger is unsuppressed, making binge eating far more likely."
An Ongoing Disease?
The NHS suggest the jabs for people with weight-linked health risks, accompanied by recommended diet and exercise modifications.
A number of clinicians contend that, given the likelihood of weight regain, the therapy is often ongoing.
This perspective is reinforced by pharmaceutical companies, who say that the findings "highlight the chronic nature of excess weight," akin to managing conditions like diabetes.
User Experiences
People who have stopped the medication report a powerful return of hunger.
"I experienced a switch flipping and you're instantly extremely hungry," said one woman.
This challenge is worsened if patients have not adopted permanent lifestyle or habit modifications during therapy.
Growing Use
Recent estimates suggest that millions of adults in the UK have tried these injections in the last 12 months, with interest continuing to grow.
- Use is higher among females than men.
- The middle-aged age group shows the highest usage rates.
- A large proportion access the medications through private prescriptions rather than the NHS.
Ultimately, experts stress that while GLP-1 drugs are potent tools for weight loss, they are not a standalone cure and maintained weight loss hinges on combined behavioural changes.
