Fresh analysis reveals that people who discontinue new weight-loss injections like Wegovy and Mounjaro may regain lost weight far faster than those who end traditional lifestyle programs.
Research printed in a prominent health publication demonstrates that while overweight people often shed a large proportion of their body weight while using the jabs, the mass comes back at an average rate of 0.8 kg per month after stopping.
"Individuals buying such medications must be cognizant of the danger of quick rebound weight gain when the medication ends," cautioned expert Dr. Susan Jebb.
This pace of regain means a return to original weight within about a year and a half.
Analyzing Approaches
The research, which looked at dozens of studies involving over 9,000 of patients, compared the effects of the injectable medications with conventional dieting.
Scientists emphasize that people who lose weight through diet and exercise usually experience a less rapid creep back—approximately 100 grams monthly—after stopping.
The Reason for the Rapid Rebound
Doctors suggest the mechanism of the drugs is key to understanding the amplified weight return.
These medications copy a body's own chemical called GLP-1, which moderates feelings of fullness.
"Sustained high doses of the hormone concentrations several times higher than normal might result in the body to generate a reduced amount of its endogenous hormone, and may also reduce sensitivity to its effects," said Dr. Adam Collins, a dietetics expert.
"Withdrawal of this GLP-1 'fix' leads to appetite is uncontrolled, making excessive eating far more likely."
A Lifelong Issue?
The NHS recommend the injections for people with obesity-related health risks, alongside prescribed lifestyle changes.
A number of clinicians contend that, considering the likelihood of weight regain, the therapy is often ongoing.
This perspective is echoed by pharmaceutical companies, who say that the results "highlight the persistent nature of obesity," akin to managing conditions like high blood pressure.
User Testimonies
People who have discontinued the medication explain a powerful resurgence of appetite.
"It was like a trigger activating and you're instantly starving," said an individual.
This difficulty is exacerbated if individuals have not adopted lasting lifestyle or habit changes during therapy.
Significant Use
Survey data indicate that a significant number of people in the UK have tried weight-loss jabs in the past year, with interest remaining high.
- Use is greater among women compared to males.
- The middle-aged age group shows the greatest level of interest.
- A large proportion access the medications through private prescriptions rather than public health services.
In conclusion, researchers stress that while GLP-1 drugs are effective agents for shedding pounds, they are not a magic cure and lasting health benefits likely depends on integrated lifestyle management.
