Document Summary

* when energy intake exceeds energy output, there is a gain in weight. * excess energy can come from protein, fat or carbohydrate. * excess protein is converted to fat, but this is inefficient and indirect. * excess carbohydrate is converted to fat, but this is inefficient and indirect. * excess fat is effectively converted to fat. * primary role of carbohydrates is to provide glucose to cells. * excess glucose is stored as glycogen in liver (8% wet weight preferred organ to store glycogen) and muscles (0-1% wet weight) * if glycogen stores are depleted, the body makes glucose from protein to a certain extend to provide energy using glucogenic amino acids. * gluconeogenesis is the conversion of protein to glucose and occurs in the liver. ), fats are broken down first followed by proteins to provide energy to the body. * glucogenic amino acids from protein are converted to pyruvate which can form glucose by reverse glycolysis.
