Our daily food choices resupply the potential energy, or fuel, that the body requires to continue to function normally. This energy takes three forms: carbohydrate, fat, and protein. (See table 2.1, Estimated Energy Stores in Humans.) The body can store some of these fuels in a form that offers muscles an immediate source of energy. Carbohydrates, such as sugar and starch, for example, are readily broken down into glucose, the bodyâs principal energy source. Glucose can be used immediately as fuel, or can be sent to the liver and muscles and stored as glycogen.
Carbohydrate. Carbohydrates, on the other hand, can only be stored in limited quantities, so the body is eager to use them for energy. We think of carbs as the [nutrient] that's used first, says Eric Westman, MD, MHS, director of the Lifestyle Medicine Clinic at Duke University Medical Center.hile these fats are a welcome source of energy for most of the body, a few types of cells, such as brain cells, have special needs. These cells could easily run on glucose from the diet, but they can't run on fatty acids directly.
