OK, so I know the conversation has changed but I couldn't wait to find this thread today to comment on the original post. Today I was discussing my way of eating with a diabetic man and when I told him that I keep all carbs to 20 grams or less a day, he reacted with a stunned "Wow!" Then he said "please eat more carbs than 20 grams a day. That is too low and you will damage your brain."
