Fresh analysis reveals that individuals who come off blockbuster GLP-1 drugs like Mounjaro or Wegovy may regain lost weight far faster than those who stop conventional lifestyle plans.
Findings released in a leading medical journal points out that while overweight individuals frequently drop substantial amounts of their total mass while on the medication, the weight is regained at an estimated rate of 0.8 kg per month after stopping.
"People purchasing these treatments should be informed of the danger of rapid weight regain when the treatment is stopped," cautioned researcher Dr. Susan Jebb.
That rate of recovery implies a reversion to starting mass in about a year and a half.
Analyzing Treatments
The analysis, which looked at dozens of trials involving thousands of patients, compared the outcomes of these new drugs with other pills.
Researchers point out that individuals who shed pounds through diet and exercise usually have a less rapid creep back—around 0.1 kg a month—once they finish.
Explaining the Quick Regain
Experts believe the mode of action of the jabs accounts for the accelerated rebound.
The injections imitate a natural hormone called glucagon-like peptide-1, which controls appetite.
"Long-term administration of GLP-1 levels far above than normal might result in the system to generate a reduced amount of its own natural GLP-1, and could reduce responsiveness to its actions," explained Dr. Adam Collins, a nutrition researcher.
"Stopping of this hormone supplement means appetite is unsuppressed, making excessive eating a significant risk."
A Lifelong Condition?
The NHS advise the jabs for people with weight-linked medical conditions, accompanied by recommended lifestyle changes.
Many experts argue that, due to the high risk of relapse, the therapy is often life-long.
This perspective is echoed by drug manufacturers, who say that the results "highlight the persistent nature of obesity," comparing it to managing diseases like high blood pressure.
User Experiences
Users who have come off the jabs explain a intense resurgence of hunger.
"It was like a trigger flipping and I was suddenly starving," described a patient.
The struggle is compounded if individuals have not adopted permanent lifestyle or habit modifications during treatment.
Significant Use
Survey data suggest that a significant number of adults in the UK have tried these injections in the past year, with demand being substantial.
- Adoption is higher among women than men.
- The 40s and 50s age group shows the highest usage rates.
- A large proportion obtain the medications through private healthcare rather than public health services.
Ultimately, experts stress that while the jabs are potent agents for weight loss, they are not a permanent cure and long-term success likely depends on ongoing lifestyle management.
