Metаbоlic Respоnse tо FASTING During the fаsting stаte, or more than 3 hours after eating a meal, the stomach and small intestine are empty, favoring a shift in metabolism from an anabolic state to a catabolic state. In the early stages of fasting, breakdown of liver and muscle glycogen into glucose is favored and lipolysis from the adipose tissue provides energy. In the later stages of fasting, glycogen stores are depleted, muscle is broken down to provide amino acids for energy and gluconeogenesis, and ketogenesis yields ketone bodies to fuel the brain. Review this focus figure and then complete the associated questions..
