Energy is obtained by proteins/carbohydrates in your body.
Protein, fat, and carbohydrates provide energy for the body. Carbohydrates provide bodily energy the quickest. Fats/Lipids are stored as body fat for later/emergency usage. Proteins usually are used to create bones, tissue, and muscle - they don't really provide energy.
