New research suggests that individuals who come off blockbuster GLP-1 drugs like Mounjaro or Wegovy tend to recover reduced body mass much more quickly than those who stop traditional diet and exercise regimens.
Published data in a leading medical journal demonstrates that while obese individuals frequently drop a large proportion of their body weight while using the jabs, the weight returns at an average rate of nearly a kilo each month upon discontinuation.
"Users using such drugs must be cognizant of the potential of quick rebound weight gain when the treatment ends," cautioned researcher Dr. Susan Jebb.
This pace of recovery suggests a reversion to pre-treatment weight within about a year and a half.
Analyzing Treatments
The research, which looked at dozens of trials involving thousands of patients, compared the effects of these new drugs with other pills.
The team emphasize that people who lose weight through dieting generally see a more gradual creep back—perhaps 100 grams monthly—post-intervention.
Understanding the Quick Rebound
Experts propose the way of the jabs accounts for the heightened weight return.
These medications imitate a natural hormone called GLP-1, which helps regulate feelings of fullness.
"Sustained high doses of GLP-1 levels several times higher than the body's typical production might result in the system to generate a reduced amount of its endogenous GLP-1, and could reduce responsiveness to its actions," said Dr. Adam Collins, a dietetics researcher.
"Withdrawal of this medication results in appetite is no longer kept in check, making binge eating far more likely."
A Chronic Condition?
The NHS recommend the jabs for individuals with weight-linked medical conditions, alongside recommended lifestyle changes.
Many experts say that, considering the significant potential of relapse, the treatment should be considered life-long.
This view is supported by pharmaceutical companies, who state that the results "emphasize the long-term character of obesity," similar to managing conditions like hypertension.
Patient Testimonies
Users who have come off the medication explain a powerful return of hunger.
"It was like something flipping and you become extremely hungry," described one woman.
This challenge is worsened if individuals have not adopted lasting dietary or behavioural modifications during treatment.
Widespread Adoption
Figures indicate that a significant number of people in the UK have used weight-loss jabs in the last 12 months, with desire being substantial.
- Use is higher among females compared to men.
- The middle-aged age group shows the highest usage rates.
- Many access the medications through private prescriptions rather than the NHS.
In conclusion, clinicians emphasize that while these medications are effective agents for shedding pounds, they are not a standalone fix and maintained weight loss hinges on integrated behavioural changes.
