Fresh analysis indicates that patients who come off blockbuster slimming jabs like Wegovy and Mounjaro can put back on shed pounds at a significantly accelerated pace than those who end traditional lifestyle plans.
Published data in a major health publication points out that while overweight individuals can lose substantial amounts of their body weight while undergoing treatment, the weight comes back at an average rate of 0.8 kg per month once they quit.
"Individuals using these treatments need to be informed of the danger of fast rebound weight gain when the medication concludes," cautioned researcher Dr. Susan Jebb.
This pace of regain suggests a reversion to pre-treatment mass within about a year and a half.
Comparing Treatments
The study, which examined dozens of trials involving over 9,000 of participants, compared the effects of the injectable medications with other pills.
Researchers note that individuals who shed pounds through diet and exercise generally experience a less rapid weight regain—perhaps 100 grams monthly—once they finish.
Explaining the Fast Regain
Experts believe the mechanism of the drugs explains the heightened rebound.
GLP-1 drugs copy a natural hormone called GLP-1, which moderates hunger.
"Artificially providing the hormone levels several times higher than normal could lead to the body to produce less of its endogenous hormone, and may also lessen sensitivity to its effects," explained Dr. Adam Collins, a dietetics researcher.
"Discontinuation of this GLP-1 'fix' results in appetite is unsuppressed, making binge eating far more likely."
A Chronic Disease?
Medical guidelines suggest the injections for individuals with obesity-related medical conditions, alongside prescribed diet and exercise modifications.
Professionals contend that, due to the significant potential of weight regain, the treatment is often ongoing.
This opinion is echoed by pharmaceutical companies, who state that the findings "emphasize the persistent nature of obesity," similar to managing conditions like diabetes.
User Testimonies
Users who have stopped the medication explain a sudden return of appetite.
"It was like something that goes on and I was suddenly extremely hungry," described a patient.
This challenge is exacerbated if users have not established sustainable lifestyle or habit modifications during treatment.
Widespread Adoption
Survey data indicate that a significant number of people in the UK have tried these injections in the past year, with desire being substantial.
- Use is greater among women compared to men.
- The middle-aged age group shows the greatest level of interest.
- Many obtain the medications through private healthcare rather than the NHS.
Ultimately, clinicians emphasize that while these medications are powerful tools for weight loss, they are not a permanent fix and lasting health benefits likely depends on combined behavioural support.
