Especially in men, metabolic syndrome appears to be associated with reduced cognitive function in middle aged folks. The people with metabolic syndrome were more likely to have low-moderate levels of physical activity, much more likely to have abdominal obesity (beer belly, or what some have called “soda belly“), high trigylcerides, low “good: cholesterol (HDL), high fasting blood sugar, and high blood pressure (> 130/85).
In a new study, MRI exams showed normal brain structure, despite cognitive impairment. The impaired cognitions seems to be related to the state of inflammation. Obesity is an inflammatory disease; fat cells produce chemicals which may actually poison or impair parts of the brain.
After having lost weight, I feel “sharper.” My good cholesterol has gone up (exercise can do this), my blood pressure has gone down (I no longer take medication for it), and my waist has shrunk.
