Three types of fats, Saturated, unsaturated and transfats.
Saturated fats, solid at room temp. are found in meat, dairy, lard, beef tallow, coconut and palm kernal oils. Saturated fats are a good source of stored energy for the body, insulate vital tissues against the cold, provide fat- soluble vitamins & enhance the immune system.
The problem with satrated fats is excess consumption than the fats themselves.
Two types of unsaturated fats: Monounsaturated and Polyunsaturaed.
Monounsaturated fats, solid at cold temp. Include canola oil, olive oil, peanuts, almonds, cashews & avocados. They metabolize quickly and can increase weight because the body mostly uses saturated fats for energy.
Olive oil, clarified butter, sesame oil does not go rancid.
Polyunsaturated fats are found in fish, vegetable oils & Botanicals. Quickly damaged by heat and light, use quickly or refrigerated in dark containers. From these fats we obtain essential fatty acids (EFA's) known as Vitamin F.
Transfats are "modern" manufactured oils & hands down, the worst for the body. Include hydrogenated & partially hdrogenated vegetable shortening, margarine & soybean oil. Making process gets rid of the EFA's, creating a chemical makeup closer to plastic than nature-made.
Transfats cannot be broken down in the body, but stored in fat tissues, thus stress & leading to diseases such as cancer, obesity, diabetes, heart diseases, a depressed immune system & formation of free radicals.
Fats ar needed to lose fat! The problem isn't the fats but the amount of fat intake!
