Fresh analysis reveals that patients who stop using new GLP-1 drugs like Wegovy and Mounjaro tend to recover reduced body mass at a significantly accelerated pace than those who end traditional lifestyle plans.
Findings released in a leading medical journal points out that while obese individuals often shed substantial amounts of their total mass while on the medication, the weight returns at an average rate of nearly a kilo each month after stopping.
"Individuals purchasing these medications must be informed of the risk of fast rebound weight gain when the therapy is stopped," warns expert Dr. Susan Jebb.
This pace of regain means a return to original weight within about a year and a half.
Comparing Treatments
The study, which looked at 37 of trials involving over 9,000 of participants, contrasted the effects of the injectable medications with other pills.
The team emphasize that individuals who shed pounds through diet and exercise typically see a less rapid weight regain—around 100 grams monthly—once they finish.
Explaining the Quick Regain
Nutrition scientists propose the mechanism of the jabs explains the heightened regain.
GLP-1 drugs mimic a body's own chemical called GLP-1, which helps regulate hunger.
"Artificially providing GLP-1 levels several times higher than normal may cause the system to generate a reduced amount of its own natural hormone, and may also diminish sensitivity to its actions," explained Dr. Adam Collins, a nutrition expert.
"Withdrawal of this hormone supplement means hunger is uncontrolled, making binge eating a significant risk."
An Ongoing Issue?
The NHS suggest the injections for people with weight-linked health risks, accompanied by recommended lifestyle changes.
A number of clinicians contend that, due to the significant potential of relapse, the treatment might need to be long-term.
This view is echoed by drug manufacturers, who say that the results "emphasize the chronic nature of excess weight," similar to managing conditions like hypertension.
Patient Testimonies
People who have stopped the medication describe a intense resurgence of appetite.
"I experienced something that goes on and you're instantly starving," recalled an individual.
This challenge is exacerbated if individuals have not developed permanent lifestyle or habit modifications during treatment.
Significant Interest
Survey data indicate that millions of people in the UK have tried these injections in the past year, with desire being substantial.
- Adoption is higher among females than males.
- The middle-aged demographic shows the highest usage rates.
- A large proportion obtain the drugs through private prescriptions rather than the NHS.
In conclusion, experts caution that while GLP-1 drugs are effective agents for weight loss, they are not a magic solution and long-term success relies on ongoing behavioural changes.
