Just my little input on this. A guy I train with who is a 40+ year old machine swears by raw egg and fruit juice blended for 1 second in a blender as a post workout drink. I've been doing it for two weeks and I'm sold. He also got me into Chia Seeds. Same seeds as a Chia pet. They are amazing for long sustainable energy. You just take a small hand-full of them and crush them up, wisp them in some fruit juice for like 5 min and then let it sit and gel up. Eat a small spoonful whenever you feel tired throughout the day. Been using them for pre-workout and mid-day with my lunch. I would say I work out way more than most people(running 25+ miles a week with a full gym routine and MMA practice) and eating sensible meals with 4 raw eggs and juice post workout and Chia Seeds pre-workout have done wonders for me. Recently I have been reading about black rice....thinking of a "black diet" dinner (black rice, black beans and a lean meat).
