Yale's log sheet lets you enter blood glucose readings, insulin dosages, carbohydrate grams, and exercise (which you can put on a scale of 1 to 5) for any hour of the day. I met with him in Montreal in August 2002, and at that time he authorized me to make his log sheet available on my Web site. There are a lot of different log sheets out there, but the best, in my opinion, is one developed by Jean-François Yale, M.D., Associate Professor of Medicine, Crabtree Nutrition Laboratories, McGill Nutrition and Food Science Centre, Royal Victoria Hospital, and Director, Metabolic Day Centre.
