Its a Habit I picked up when Climbing the Big Hills. Big Breakfast then Little and often drinking water often as you could. Climbing you had to be carefull of Body weight ratio power, plus the lighter you were the more chance the Rope had of stopping you hitting the deck. Also eating at night wasnt a good idea only having Head Torches to do things. Plus after 7 your Metabolism drops and doesnt need the Fuel its how it works. Hope it was of interest.
