The metabolic processes with which we are affected during the Starvation-Feeding cycle are:

  • glycogenesis,
  • glycogenolysis,
  • gluconeogenesis,
  • glycolysis,
  • fatty acid synthesis,
  • lipogenesis,
  • lipolysis,
  • fatty acid oxidation,
  • tricarboxylic acid (TCA) cycle activity, and
  • Ketogenesis
