New research indicates that patients who come off blockbuster GLP-1 drugs like Mounjaro or Wegovy may regain reduced body mass far faster than those who end traditional lifestyle programs.
Research printed in a prominent health publication points out that while obese individuals frequently drop substantial amounts of their total mass while on the medication, the weight returns at an average rate of nearly a kilo each month upon discontinuation.
"Users purchasing such drugs should be informed of the danger of quick weight regain when the medication concludes," stated expert Dr. Susan Jebb.
This pace of recovery implies a return to starting mass within about a year and a half.
Analyzing Therapies
The analysis, which examined dozens of trials involving over 9,000 of participants, contrasted the effects of the injectable medications with older methods.
The team note that individuals who lose weight through dieting typically experience a less rapid creep back—around 0.1 kg a month—after stopping.
Understanding the Quick Regain
Experts propose the way of the jabs accounts for the heightened weight return.
These medications copy a natural hormone called GLP-1, which helps regulate feelings of fullness.
"Artificially providing the hormone concentrations several times higher than normal could lead to the system to produce less of its endogenous GLP-1, and could diminish responsiveness to its actions," said Dr. Adam Collins, a dietetics specialist.
"Withdrawal of this hormone supplement results in appetite is unsuppressed, making binge eating far more likely."
A Chronic Condition?
The NHS advise the jabs for individuals with weight-linked health risks, accompanied by prescribed lifestyle changes.
A number of clinicians say that, considering the high risk of relapse, the treatment might need to be life-long.
This perspective is supported by pharmaceutical companies, who state that the findings "underscore the persistent nature of obesity," similar to managing diseases like hypertension.
Patient Testimonies
Users who have come off the jabs describe a intense return of hunger.
"I experienced a switch activating and you become ravenous," described an individual.
This challenge is compounded if individuals have not adopted lasting dietary or behavioural changes during treatment.
Widespread Use
Recent estimates suggest that millions of adults in the UK have used weight-loss jabs in the last 12 months, with demand remaining high.
- Use is more common among women compared to males.
- The 40s and 50s age group shows the greatest usage rates.
- Many access the medications through private healthcare rather than the NHS.
Ultimately, clinicians caution that while the jabs are effective tools for weight loss, they are not a magic solution and maintained weight loss hinges on integrated lifestyle changes.
