A study in the journal Archives of Neurology found that obesity, high cholesterol and high blood pressure can each double your risk of developing Alzheimer's disease or dementia. After analyzing data compiled from 2,300 test subjects over a 21-year period, researchers concluded that being obese carried 2.1 times the risk for developing dementia, in contrast to those who were of normal weight (BMI below 25). Having systolic blood pressure greater than 140 mm Hg and total cholesterol levels greater than 6.5 mmol/L also each carried double the risk.

Having all three risk factors has an additive effect, resulting in a risk 6.21 times that of participants who were not obese and had neither high blood pressure nor high cholesterol. Researchers therefore suggest that eliminating even one risk factor can decrease the risk of developing dementia or Alzheimer's disease.
