"With this all in mind, many formerly high-protein, low-carbohydrate diets are now advocating eating enough carbohydrate to prevent protein destruction. Such diets are called the protein-sparing, low carbohydrate diets. These diets are usually still far too low in carbohydrate to completely prevent protein break down. Most allow about 60 grams of carbohydrate a day and we have already seen that the brain alone daily requires about 140 grams"

Hmmm, then the Inuit, and others who eat similar diets must have no brain function whatsoever, since their diet is virtually void of carbohydrates.
