A recent study reveals that people who come off popular GLP-1 drugs like Mounjaro or Wegovy tend to recover lost weight far faster than those who halt traditional diet and exercise programs.
Published data in a major medical journal points out that while overweight individuals can lose substantial amounts of their body weight while undergoing treatment, the mass is regained at an estimated rate of nearly a kilo each month after stopping.
"Users buying such treatments should be cognizant of the potential of quick weight regain when the medication ends," stated expert Dr. Susan Jebb.
This pace of recovery means a return to starting mass in about a year and a half.
Weighing Treatments
The analysis, which examined 37 of trials involving over 9,000 of participants, contrasted the outcomes of GLP-1 agonists with conventional dieting.
The team point out that people who lose weight through diet and exercise typically experience a slower creep back—approximately 0.1 kg a month—after stopping.
Understanding the Fast Regain
Doctors propose the mechanism of the jabs is key to understanding the accelerated rebound.
GLP-1 drugs imitate a body's own chemical called GLP-1, which controls appetite.
"Long-term administration of GLP-1 concentrations several times higher than the body's typical production might result in the body to produce less of its endogenous GLP-1, and may also lessen responsiveness to its effects," said Dr. Adam Collins, a dietetics researcher.
"Stopping of this hormone supplement results in appetite is no longer kept in check, making excessive eating far more likely."
An Ongoing Condition?
Medical guidelines recommend the injections for people with obesity-related medical conditions, accompanied by recommended diet and exercise modifications.
Professionals contend that, considering the significant potential of weight regain, the treatment should be considered long-term.
This view is reinforced by drug manufacturers, who say that the results "highlight the chronic nature of excess weight," comparing it to managing conditions like hypertension.
Patient Experiences
Individuals who have come off the jabs describe a powerful resurgence of appetite.
"It was like something flipping and I was suddenly starving," recalled one woman.
The struggle is worsened if patients have not adopted lasting lifestyle or habit modifications during treatment.
Widespread Adoption
Recent estimates indicate that a significant number of people in the UK have tried these injections in the past year, with demand continuing to grow.
- Adoption is more common among women than males.
- The 40s and 50s age group shows the greatest usage rates.
- A large proportion access the drugs through private healthcare rather than public health services.
In conclusion, clinicians stress that while these medications are potent tools for weight loss, they are not a permanent fix and maintained weight loss likely depends on combined behavioural support.
