Fresh analysis indicates that people who stop using popular GLP-1 drugs like Mounjaro or Wegovy tend to recover lost weight at a significantly accelerated pace than those who halt conventional diet and exercise regimens.
Findings released in a leading health publication points out that while overweight individuals often shed a large proportion of their body weight while on the medication, the weight is regained at an average rate of 0.8 kg per month after stopping.
"Individuals using such drugs should be cognizant of the danger of fast weight regain when the medication concludes," cautioned lead investigator Dr. Susan Jebb.
This pace of recovery means a return to original weight in about a year and a half.
Comparing Approaches
The analysis, which reviewed dozens of trials involving over 9,000 of participants, compared the results of the injectable medications with other pills.
Scientists note that individuals who lose weight through dieting generally see a more gradual weight regain—around 0.1 kg a month—post-intervention.
Explaining the Fast Rebound
Experts believe the mechanism of the jabs explains the accelerated weight return.
These medications imitate a body's own chemical called GLP-1, which helps regulate feelings of fullness.
"Artificially providing the hormone levels several times higher than the body's typical production might result in the body to generate a reduced amount of its own natural hormone, and may also lessen responsiveness to its actions," said Dr. Adam Collins, a nutrition expert.
"Discontinuation of this hormone supplement leads to hunger is unsuppressed, making excessive eating a significant risk."
A Chronic Issue?
Health authorities recommend the jabs for people with obesity-related medical conditions, alongside recommended diet and exercise modifications.
Professionals say that, considering the likelihood of relapse, the therapy might need to be life-long.
This opinion is echoed by drug manufacturers, who state that the findings "emphasize the long-term nature of obesity," similar to managing conditions like diabetes.
User Accounts
Users who have discontinued the medication explain a sudden return of hunger.
"It felt as if a trigger that goes on and you become starving," described one woman.
This challenge is worsened if patients have not adopted lasting lifestyle or habit modifications during treatment.
Significant Interest
Recent estimates show that a significant number of adults in the UK have used these injections in the past year, with interest being substantial.
- Use is higher among women than men.
- The middle-aged age group shows the highest usage rates.
- A large proportion obtain the medications through private healthcare rather than public health services.
In conclusion, researchers caution that while these medications are potent tools for shedding pounds, they are not a magic fix and lasting health benefits likely depends on combined behavioural management.
