Leadman*, ultrarunner, sports dietitian and former olympic athlete coach, Bob Seebohar says that we should, "eat to train, not train to eat". Our fueling is as important in our training as aerobic and anaerobic training. Bob even wrote the book on it, Metabolic Efficiency Training, Teaching the Body to Burn More Fat. He discusses the simple methodology he prescribes to athletes to help them improve their nutrition and fuel burning with periodization and the simple "hand method" of fueling.
