Olestra is a fat substitute created by attaching fatty acids to a sugar molecule, producing a large molecule that the digestive system cannot break down. Because it isn’t digested or absorbed, it provides no calories. It isn’t a carbohydrate, protein, or amino acid—those categories are metabolized to supply energy or build body tissues, whereas Olestra remains unabsorbed and energy-free. In practice, this means it can replace fat in foods without adding calories, though high use can affect the absorption of fat-soluble vitamins.
