Fat: Can't Live Without It
Think back on all those past dieting failures. Did you completely eliminate fat in one of those diets? Didn't last long on that one, did you? If being ravenous within an hour of eating a plate of steamed veggies didn't do you in, then surely the lack of energy and fuzzy thinking did.
Let's talk about why you need fat in your diet. Animal and vegetable fats provide valuable, concentrated energy; they also provide the building blocks for cell membranes and a variety of hormones and hormone-like substances. Fats slow the absorption of nutrients into your system so that you can go longer without feeling hungry, and they aid in sugar and insulin metabolism, which helps you lose weight. In addition, they act as carriers for important fat-soluble vitamins, aid in the absorption of vital minerals, and help facilitate a host of other important biological operations within the body.
Convinced? Good! I know your next question is, How do I know if foods that contain fat are good to eat or not? It all boils down to molecular structure, and how different kinds of fat molecules affect your body. The fats considered to be healthiest come from plants and vegetables. They are called unsaturated fats, and here's a basic look at the science behind them: Unsaturated fat molecules contain at least one pair of carbons linked by a double bond. Since hydrogen can't break this bond, it can't bond with these carbons, so any fat molecule with one or more double-bonded carbons is considered "unsaturated" by hydrogen. Now keep your eyes peeled for the magic word — unsaturated — on food packaging.
