Having played ice hockey for a million years our Coach made us document all of our meals and portion sizes. Then we had to self critique our energy levels for all three periods. Invariably this led to modifications of caloric intake and more importantly type of intake. While I hated that aspect of the game I sure learned a lot. As the Captain, I had to do it religiously or I could not enforce it. Same token I learned not to be shredded and at game weight for first game of season. Seasons are long and Hockey is hard on the body. It is easy to lose 15 pounds over the course of a season. If I started season about 15 pounds heavy it helped to prevent injuries and not be banged up come playoffs. Everybody is playing hurt during playoffs, the key was just to be a bit more durable than the next guy. Over the years I learned a lot about what worked for my body and metabolism and what did not. Peanut Butter for the win!
