Lets see, this one is from the Joslin center which is a diabetic center affiliated with Harvard Medical School and considered the top dog in the field. Oh, and that probably means it is the best in the WORLD! Note this is a ccarb guideline for someone that has DIABETES for gods sake!
"For example, a 6' 2" tall man with diabetes who weighs 180 pounds and wants to maintain his current weight might be told he could eat 350 grams of carbohydrate spread out over the day. His goal would be to spread those grams out over the course of the day so that he doesn't send his blood sugars too high at any one time. If he is taking insulin or oral diabetes medication, he might also have to manage when he eats his carbohydrate in such a way that there is enough sugar from his meals in his bloodstream when his medication is working its hardest."
Oh, I can get some from MIT as well, they have a health center affiliated with HArvard. Might I suggest that YOU people are the ones that have the erroneous data?
