Are You A Fat Idiot?

The brains of obese individuals may be shrinking. According to a recent study completed at Boston University Medical Center the brain volume of overweight and obese individuals is significantly less than that of their normal weight counterparts.
Researchers tested over 700 individuals who were previously enrolled in the Framingham Offspring Cohort. Visceral and subcutaneous body fat was assessed via abdominal CT scan, while brain volume was measured using MRI. Total brain volume was then compared to the above body composition factors, in addition to Body Mass Index (BMI) and waist circumference.
Interestingly the data indicated an inverse relationship between body fat and brain size. The most significant link was between visceral body fat and total brain volume. Simply, the higher the fat the smaller the brain.
Scientists are expecting to explore the underlying mechanisms and speculate hormones such as adiponectin, leptin, resistin or ghrelin may be responsible in part for the brain atrophy noted.
Why is this study important? Researchers have previously uncovered links between obesity and a greater risk for early onset of Alzheimer’s Disease and/or dementia. Until now, the underlying mechanisms behind such a relationship were only speculative. Although there is limited evidence to indicate cognitive impairment resulting from brain shrinkage, scientists hope to find a link that will allow them to understand the obesity-disease relationship.

    I guess as you gain more weight the only thing that gets smaller is your brain which makes you less smart. The title for this post is right on point. Lets get fit!
