Answer
Application of heat to the meat changes the state of saturated fats from semisolid to liquid form. So, liquid fats drain from the grilled meat, resulting in less percentage of saturated fats, whereas raw meat contains all the saturated fats in it.
Work Step by Step
Raw meat contains saturated fats. When meat is grilled, the saturated fat in the semisolid state becomes liquid fat. On application of heat, fat in the final product becomes less saturated.
