Unformatted text preview: ATP. Fat can never be used as fuel anaerobically. In aerobic metabolism, used in lower intensities, oxygen is used for energy production because the circulatory system is capable of supplying adequate amounts. This pathway for ATP production predominates in long duration aerobic exercise. The body can use carbs, fatty acids, and amino acids as fuel This is also the only way the body can burn fat as fuel Fate of a Bowl of Oatmeal Breakfast replenishes muscle glycogen (if low after exercise), otherwise it would go into body fat anabolic process Exercise after breakfast food is absorbed into blood, taken up by muscle and burned to power run Skipping meals tends to cause more muscle loss than fat loss...
