New research indicates that patients who come off popular weight-loss injections like Wegovy and Mounjaro may regain reduced body mass far faster than those who end traditional lifestyle regimens.
Findings released in a leading health publication demonstrates that while overweight individuals often shed a large proportion of their total mass while undergoing treatment, the mass returns at an estimated rate of nearly a kilo each month after stopping.
"Individuals buying such medications should be aware of the potential of rapid rebound weight gain when the therapy concludes," warns expert Dr. Susan Jebb.
That rate of regain means a return to original mass in about 18 months.
Analyzing Approaches
The analysis, which examined 37 of studies involving over 9,000 of participants, contrasted the outcomes of GLP-1 agonists with other pills.
The team point out that people who shed pounds through lifestyle changes alone typically see a slower creep back—around 100 grams monthly—post-intervention.
Understanding the Quick Regain
Doctors suggest the way of the drugs accounts for the amplified regain.
The injections imitate a natural hormone called glucagon-like peptide-1, which helps regulate appetite.
"Long-term administration of the hormone concentrations several times higher than normal might result in the system to generate a reduced amount of its endogenous GLP-1, and could diminish responsiveness to its effects," noted Dr. Adam Collins, a nutrition researcher.
"Discontinuation of this medication means hunger is uncontrolled, making overeating a significant risk."
A Lifelong Issue?
The NHS suggest the jabs for people with weight-linked health risks, accompanied by prescribed lifestyle changes.
Professionals contend that, considering the high risk of relapse, the therapy should be considered life-long.
This opinion is supported by drug manufacturers, who state that the results "emphasize the long-term nature of obesity," akin to managing conditions like hypertension.
Patient Experiences
People who have come off the medication report a sudden resurgence of appetite.
"I experienced a trigger flipping and you're instantly extremely hungry," described a patient.
This challenge is worsened if users have not developed permanent lifestyle or habit modifications during treatment.
Growing Use
Recent estimates indicate that a significant number of adults in the UK have tried weight-loss jabs in the past year, with interest being substantial.
- Use is higher among females compared to men.
- The middle-aged demographic shows the greatest usage rates.
- Many access the medications through private healthcare rather than public health services.
Finally, researchers caution that while the jabs are potent agents for shedding pounds, they are not a standalone fix and lasting health benefits hinges on integrated lifestyle support.
