Fresh analysis reveals that people who discontinue blockbuster GLP-1 drugs like Mounjaro or Wegovy can put back on shed pounds far faster than those who end traditional lifestyle plans.
Findings released in a major health publication shows that while obese individuals can lose substantial amounts of their body weight while undergoing treatment, the mass is regained at an average rate of nearly a kilo each month once they quit.
"Individuals buying such medications must be cognizant of the risk of rapid weight regain when the therapy is stopped," cautioned lead investigator Dr. Susan Jebb.
That rate of regain means a return to original mass within about a year and a half.
Weighing Treatments
The research, which looked at dozens of trials involving thousands of patients, contrasted the outcomes of GLP-1 agonists with conventional dieting.
Researchers note that people who shed pounds through dieting typically see a less rapid creep back—perhaps 100 grams monthly—after stopping.
Explaining the Quick Regain
Nutrition scientists suggest the way of the jabs accounts for the heightened regain.
The injections imitate a body's own chemical called GLP-1, which helps regulate feelings of fullness.
"Sustained high doses of the hormone levels several times higher than the body's typical production may cause the body to generate a reduced amount of its own natural hormone, and could diminish sensitivity to its effects," explained Dr. Adam Collins, a dietetics specialist.
"Stopping of this hormone supplement leads to hunger is unsuppressed, making excessive eating a significant risk."
A Lifelong Disease?
Medical guidelines suggest the jabs for individuals with weight-linked medical conditions, accompanied by recommended diet and exercise modifications.
A number of clinicians say that, considering the high risk of weight regain, the treatment might need to be ongoing.
This opinion is supported by drug manufacturers, who state that the findings "emphasize the chronic nature of obesity," similar to managing conditions like diabetes.
Patient Accounts
People who have discontinued the jabs report a sudden return of cravings.
"It was like a switch flipping and you're instantly ravenous," described an individual.
This challenge is worsened if individuals have not adopted permanent dietary or behavioural modifications during therapy.
Significant Interest
Recent estimates indicate that a significant number of people in the UK have used these injections in the past year, with desire being substantial.
- Use is greater among women compared to men.
- The 40s and 50s age group shows the highest level of interest.
- Many access the medications through private prescriptions rather than the NHS.
Finally, experts emphasize that while the jabs are effective tools for weight loss, they are not a standalone cure and maintained weight loss likely depends on integrated behavioural management.
