Dieting to achieve rapid weight loss need not be hard work. It can actually be quite easy and fun. It is known that dietary fiber helps to lose weight by blocking the absorption of fat in the body. On top of helping the body to flush fat through the body, dietary fiber will also help to burn the extra calories consumed. Unbelievable but true.
Fiber is the part of plant foods that cannot be digested completely, so that it passes through the digestive tract intact. Plant foods contain a mixture of different types of fibers. These fibers can be divided into soluble or insoluble, depending on their solubility in water. Insoluble fibers absorb many times their own weight in water, creating a soft bulk to the stool and hastening the passage of waste products out of the body. Soluble fibers are easily digested and when ingested, these fibers form a gel that slows the speed at which the stomach empties and the speed at which simple sugars are absorbed from the intestine.
Rapid weight loss can be achieved by consuming more fiber because fiber burns up calories by itself. This is because intestinal tract has to work harder to digest fiber foods. The body's metabolism therefore will use more energy for fiber digestion and as a result will burn most of the calories that the fiber food contains. It may sound illogical but some of the high-fiber food can actually burn up more calories than what they contain. When this happen, it will actually cause a deficit of calories thus stored body fat in the body will be used for the production of energy.
In addition to blocking fat and burning calories, fiber foods bind with water in the intestinal tract and form bulk that will give the feeling of fullness early in the course of a meal. When less food is taken, fewer calories are consumed. Since fiber food takes longer to digest, it will take a longer time feel hunger and hence reduce the possibility of snacking in between meals. High fiber foods such as fruits and vegetables, whole grain cereals and breads, yams and sweet potatoes, and legumes are low in fat calories and have a high water content. Eating high fiber food will actually allow you to eat less yet enjoy more and at the same time enjoy rapid weight loss effortlessly.
