i personally beleive that there is nothing wrong with the cornflakes and also they were used as the cheapest most easily digestable form of carbs, which they are, but bill also used fats such as flaw oil and coconut oil and knew that fats not carbs are what animals use for energs but those carbs are used in the first fifteen minutes of the work out then the fats kick in and i still beleive carbs are needed just in low percentages not high like humans need. u also have to understand that bill was putting a keep out there that was cheap and successful and he knew that cornflakes were not the best thing out there for carbs but the cheapest. you also must understand like jack said about the old man bill lnew two things no keep is good without the right weight and the right dog
