A recent study reveals that individuals who discontinue popular slimming jabs like Mounjaro or Wegovy can put back on lost weight much more quickly than those who end conventional lifestyle plans.
Published data in a major medical journal shows that while overweight individuals can lose about a fifth of their body weight while undergoing treatment, the weight comes back at an average rate of 0.8 kg per month once they quit.
"People buying such medications should be aware of the potential of fast rebound weight gain when the medication concludes," stated expert Dr. Susan Jebb.
This pace of recovery implies a reversion to original weight in about a year and a half.
Weighing Treatments
The analysis, which looked at 37 of trials involving over 9,000 of participants, compared the effects of the injectable medications with other pills.
The team emphasize that people who lose weight through dieting typically have a less rapid creep back—approximately 100 grams monthly—post-intervention.
Explaining the Rapid Regain
Experts suggest the mechanism of the injections is key to understanding the heightened weight return.
GLP-1 drugs imitate a body's own chemical called glucagon-like peptide-1, which moderates appetite.
"Artificially providing the hormone concentrations several times higher than normal might result in the system to generate a reduced amount of its own natural GLP-1, and could reduce sensitivity to its actions," noted Dr. Adam Collins, a nutrition expert.
"Stopping of this medication results in hunger is unsuppressed, making excessive eating a significant risk."
An Ongoing Issue?
Medical guidelines advise the injections for people with weight-linked medical conditions, alongside prescribed diet and exercise modifications.
Many experts say that, due to the significant potential of weight regain, the therapy should be considered life-long.
This perspective is echoed by pharmaceutical companies, who note that the results "highlight the long-term character of obesity," akin to managing diseases like high blood pressure.
Patient Testimonies
Users who have discontinued the jabs explain a powerful resurgence of appetite.
"It was like something that goes on and you're instantly extremely hungry," said one woman.
This challenge is exacerbated if individuals have not established lasting lifestyle or habit changes during treatment.
Growing Interest
Figures suggest that a significant number of adults in the UK have used these injections in the last 12 months, with interest remaining high.
- Use is more common among females compared to males.
- The middle-aged demographic shows the greatest usage rates.
- A large proportion obtain the drugs through private healthcare rather than public health services.
Finally, experts stress that while the jabs are powerful agents for weight loss, they are not a permanent cure and lasting health benefits hinges on integrated behavioural support.
