Fresh analysis reveals that people who stop using new weight-loss injections like Wegovy and Mounjaro can put back on shed pounds much more quickly than those who end conventional lifestyle programs.
Published data in a prominent medical journal demonstrates that while overweight individuals often shed about a fifth of their body weight while undergoing treatment, the weight returns at an average rate of 0.8 kg per month once they quit.
"Users buying these drugs must be aware of the danger of fast weight regain when the medication concludes," cautioned expert Dr. Susan Jebb.
Such speed of recovery suggests a return to starting weight in about 18 months.
Comparing Approaches
The analysis, which examined 37 of studies involving thousands of participants, compared the outcomes of the injectable medications with other pills.
Researchers emphasize that people who lose weight through dieting typically have a less rapid creep back—approximately 100 grams monthly—after stopping.
Explaining the Quick Regain
Doctors suggest the mechanism of the drugs accounts for the amplified weight return.
GLP-1 drugs imitate a natural hormone called GLP-1, which moderates hunger.
"Artificially providing GLP-1 levels several times higher than normal could lead to the body to produce less of its own natural hormone, and could lessen sensitivity to its effects," said Dr. Adam Collins, a dietetics expert.
"Stopping of this hormone supplement leads to hunger is no longer kept in check, making overeating far more likely."
A Lifelong Disease?
The NHS suggest the injections for people with weight-linked medical conditions, alongside prescribed diet and exercise modifications.
Many experts argue that, given the likelihood of weight regain, the therapy might need to be ongoing.
This perspective is echoed by drug manufacturers, who say that the results "highlight the persistent nature of obesity," akin to managing diseases like hypertension.
User Testimonies
People who have discontinued the jabs explain a intense return of cravings.
"It was like something activating and I was suddenly starving," recalled a patient.
This challenge is compounded if individuals have not established lasting lifestyle or habit modifications during treatment.
Widespread Adoption
Survey data show that millions of adults in the UK have used these injections in the last 12 months, with desire remaining high.
- Use is greater among women compared to males.
- The middle-aged demographic shows the greatest usage rates.
- A large proportion obtain the medications through private healthcare rather than the NHS.
Ultimately, clinicians emphasize that while the jabs are effective tools for weight loss, they are not a standalone solution and long-term success likely depends on combined lifestyle support.
