Fats are actually called lipids and are also known as triglycerides. Lipids have been given a bad reputation in the past because lipids contain more calories, ounce for ounce, than protein or carbohydrates.
- Each ounce of lipids contains more than twice the calories of an ounce of protein or carbohydrates
Functions of Lipids
- Transporting nutrients
- Serving as a backup energy source after glycogen stores are depleted
- Regulating body temperature
- Acting as a structural component of every cell membrane and organ tissue
- Starting chemical reactions that control growth and immune function
