A recent study indicates that people who come off blockbuster GLP-1 drugs like Wegovy and Mounjaro may regain lost weight at a significantly accelerated pace than those who end conventional diet and exercise programs.
Published data in a leading health publication demonstrates that while overweight individuals frequently drop substantial amounts of their body weight while on the medication, the weight is regained at an estimated rate of nearly a kilo each month once they quit.
"People buying such drugs should be informed of the danger of quick rebound weight gain when the therapy ends," cautioned researcher Dr. Susan Jebb.
Such speed of recovery suggests a return to starting mass in about a year and a half.
Comparing Therapies
The study, which looked at 37 of studies involving thousands of patients, compared the outcomes of these new drugs with other pills.
The team emphasize that people who shed pounds through diet and exercise generally experience a slower creep back—around 100 grams monthly—once they finish.
Understanding the Quick Regain
Experts suggest the mechanism of the jabs explains the amplified weight return.
GLP-1 drugs copy a natural hormone called GLP-1, which helps regulate hunger.
"Long-term administration of the hormone levels several times higher than normal could lead to the body to produce less of its endogenous GLP-1, and may also diminish sensitivity to its effects," said Dr. Adam Collins, a dietetics researcher.
"Withdrawal of this GLP-1 'fix' means hunger is unsuppressed, making overeating far more likely."
A Lifelong Issue?
Medical guidelines advise the jabs for people with weight-linked medical conditions, accompanied by prescribed lifestyle changes.
Many experts contend that, given the likelihood of relapse, the therapy might need to be ongoing.
This opinion is supported by pharmaceutical companies, who state that the findings "highlight the long-term character of excess weight," comparing it to managing diseases like diabetes.
User Accounts
Individuals who have discontinued the medication describe a powerful return of hunger.
"It was like a switch that goes on and you're instantly extremely hungry," recalled one woman.
The struggle is compounded if users have not established sustainable lifestyle or habit changes during treatment.
Growing Adoption
Recent estimates suggest that a significant number of adults in the UK have used weight-loss jabs in the last 12 months, with demand continuing to grow.
- Use is higher among women than males.
- The middle-aged demographic shows the greatest usage rates.
- Many obtain the drugs through private healthcare rather than the NHS.
Ultimately, clinicians stress that while the jabs are potent agents for weight loss, they are not a magic fix and lasting health benefits likely depends on ongoing lifestyle changes.
