Dietary fiber is one of your best foods to block both the absorption of fat and to burn up extra calories. Sounds almost too good to be true; however, it really works.
First of all, when you combine the high-fiber foods, combined with any fat in your diet, like a piece of cake or a hamburger, each gram of fiber traps fat globules by entwining them in a fiber-like web, made up of thousands of fiber strands. Once these fat globules are trapped in the fiber\'s web, they pass through the intestinal tract before they are absorbed into the bloodstream. Therefore, these fat globules are excreted in the waste material from your colon without getting absorbed and stored as fat in your body. The fiber is actually removing the fat from your body like a garbage truck removes garbage. And to underscore that fact, fat really is garbage.
Secondly, fiber actually bums up calories by itself. This is accomplished because fiber causes your intestinal tract to work harder in order to digest the fiber foods. The body\'s metabolism therefore uses more energy for this time-consuming digestion, and as a result can actually consume most of the calories that the fiber foods contain. Strange as it seems, some heavily fibered foods can actually burn up more calories than the fiber foods contain, thereby creating a deficit of calories. This causes the body to use stored body fat for the production of energy. Each gram of fiber that you consume can bum up approximately 9 calories, of which come from fat. So if you eat 30 grams of fiber a day, you actually burn up an additional 270 calories daily (30 grams fiber x 9 calories). You can actually subtract those 270 calories every day from your total daily calorie intake, without actually cutting those calories from your diet.
In addition to blocking fat and burning calories, fiber foods bind with water in the intestinal tract and fonn bulk that makes you feel full early in the course of your meal. So you eat less, and therefore you consume fewer calories at each meal. Also, your appestat (hunger mechanism) is satisfied for longer periods of time, since it takes longer to digest fiber foods, and therefore you wuf have less of a tendency to snack between meals.[/color]
