Fresh analysis indicates that patients who come off blockbuster GLP-1 drugs like Mounjaro or Wegovy may regain reduced body mass much more quickly than those who halt traditional lifestyle plans.
Research printed in a major medical journal points out that while overweight people often shed a large proportion of their body weight while on the medication, the mass comes back at an average rate of 0.8 kg per month upon discontinuation.
"People purchasing such medications should be informed of the danger of rapid weight regain when the medication ends," warns expert Dr. Susan Jebb.
This pace of regain implies a reversion to starting mass within about a year and a half.
Weighing Approaches
The study, which reviewed dozens of trials involving over 9,000 of participants, contrasted the results of GLP-1 agonists with conventional dieting.
The team note that people who lose weight through diet and exercise generally see a less rapid creep back—approximately 100 grams monthly—after stopping.
The Reason for the Quick Rebound
Nutrition scientists believe the way of the injections is key to understanding the amplified regain.
These medications mimic a natural hormone called GLP-1, which helps regulate hunger.
"Sustained high doses of GLP-1 levels far above than normal might result in the system to generate a reduced amount of its endogenous GLP-1, and could reduce sensitivity to its actions," explained Dr. Adam Collins, a nutrition expert.
"Withdrawal of this hormone supplement means appetite is no longer kept in check, making excessive eating a significant risk."
A Chronic Issue?
Medical guidelines recommend the injections for individuals with obesity-related medical conditions, accompanied by prescribed diet and exercise modifications.
Professionals argue that, considering the likelihood of weight regain, the therapy should be considered long-term.
This opinion is supported by drug manufacturers, who say that the results "underscore the chronic nature of excess weight," akin to managing diseases like high blood pressure.
Patient Experiences
Users who have come off the jabs explain a sudden resurgence of hunger.
"It was like a trigger flipping and I was suddenly ravenous," said one woman.
The struggle is exacerbated if individuals have not established lasting dietary or behavioural modifications during treatment.
Significant Interest
Figures show that a significant number of people in the UK have used weight-loss jabs in the past year, with demand remaining high.
- Adoption is higher among females than men.
- The 40s and 50s demographic shows the greatest usage rates.
- A large proportion obtain the medications through private healthcare rather than the NHS.
In conclusion, clinicians stress that while GLP-1 drugs are powerful agents for shedding pounds, they are not a magic fix and maintained weight loss likely depends on integrated lifestyle changes.
