Being overweight shrinks the brain

Not surprisingly, this study showed a strong correlation between increased Body Mass Index and brain atrophy. The effect was similar for both overweight and obese BMI values. Considering the connections between high BMI, insulin resistance, chronic inflammation and neurodegeneration, this confirms what we expected. "Bivariate analyses with corrections for multiple comparisons strongly linked body mass index (BMI), fasting plasma insulin (FPI) levels, and Type II Diabetes Mellitus (DM2) with atrophy in frontal, temporal, and subcortical brain regions."
