(B) During a prolonged fast,the body follows a specific metabolic hierarchy to maintain energy homeostasis.$1$. First,the body utilizes readily available $Glycogen$ (a carbohydrate) stored in the liver and muscles to maintain blood glucose levels.$2$. Once glycogen stores are depleted,the body shifts to burning stored $Lipids$ (fats) through the process of lipolysis and beta-oxidation.$3$. Finally,if the fast continues for an extended period,the body begins to break down structural $Proteins$ (from muscles) into amino acids to be used for gluconeogenesis to support vital organs.
