Fast fuel refers to a quick source of energy for the body. Lipids, also known as fats, are a concentrated source of energy, but they are not typically considered a fast fuel like carbohydrates. Carbohydrates are the body's preferred source of quick energy, while lipids are utilized more for long-term energy needs.
At rest, the body's fuel source is primarily fat. The body relies on stored fat for energy during periods of inactivity or low-intensity activities. Fat provides a more sustained source of energy compared to carbohydrates.
The preferred fuel source for the body is glucose.
Fat provides a concentrated source of energy in the form of calories. Each gram of fat contains 9 calories, which is more than double the amount provided by carbohydrates or proteins. Fat serves as a long-lasting and efficient fuel source for the body, especially during sustained activities like endurance exercise.
Fats serve as a concentrated source of energy, provide insulation to help regulate body temperature, aid in the absorption of fat-soluble vitamins, and act as a structural component of cell membranes.

Carbohydrates are the immediate source of energy in the body. When consumed, carbohydrates are broken down into glucose, which is then used by the body as a quick source of fuel for various bodily functions and physical activities.
Carbohydrates are the body's primary source of energy, providing a quick and readily available source of fuel. Proteins and fats also provide energy, but carbohydrates are more efficient and easily converted into energy by the body.
