Fresh analysis indicates that patients who stop using new GLP-1 drugs like Wegovy and Mounjaro may regain lost weight far faster than those who stop traditional lifestyle regimens.
Published data in a major health publication demonstrates that while overweight individuals often shed about a fifth of their total mass while using the jabs, the weight is regained at an average rate of 0.8 kg per month after stopping.
"Individuals purchasing such medications should be aware of the danger of fast weight regain when the treatment concludes," stated expert Dr. Susan Jebb.
This pace of recovery suggests a return to original mass in about one and a half years.
Weighing Treatments
The study, which examined dozens of trials involving over 9,000 of participants, contrasted the effects of these new drugs with other pills.
Researchers point out that people who shed pounds through diet and exercise generally see a slower creep back—perhaps 0.1 kg a month—post-intervention.
Understanding the Rapid Regain
Nutrition scientists propose the way of the jabs accounts for the heightened rebound.
The injections imitate a body's own chemical called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Artificially providing the hormone levels far above than the body's typical production might result in the body to generate a reduced amount of its endogenous hormone, and could reduce responsiveness to its actions," said Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this medication means hunger is uncontrolled, making binge eating a significant risk."
A Lifelong Disease?
The NHS suggest the injections for individuals with weight-linked health risks, alongside prescribed diet and exercise modifications.
A number of clinicians argue that, considering the likelihood of relapse, the treatment might need to be long-term.
This perspective is echoed by pharmaceutical companies, who say that the findings "emphasize the chronic nature of excess weight," similar to managing conditions like high blood pressure.
Patient Accounts
People who have stopped the medication describe a intense return of hunger.
"It felt as if a trigger that goes on and you become extremely hungry," recalled one woman.
This difficulty is compounded if users have not established permanent lifestyle or habit modifications during therapy.
Widespread Interest
Recent estimates indicate that a significant number of adults in the UK have used weight-loss jabs in the past year, with demand being substantial.
- Use is greater among women compared to men.
- The middle-aged demographic shows the highest level of interest.
- A large proportion access the drugs through private prescriptions rather than the NHS.
In conclusion, experts caution that while GLP-1 drugs are effective tools for weight loss, they are not a permanent solution and maintained weight loss hinges on combined behavioural support.
