Dietary fiber conduce to weight loss • 06.03.12
First, the vast majority of food rich in dietary fiber contain very little fat, such as grains, legumes, fruits and vegetables. Dietary fiber has weight and big volume, but can not produce energy, so high dietary fiber is usually the energy-density food. Compared with the energy-density food (such as fat meat, butter, fried food, cake and candy), eating food with the same weight are more conducive to weight control.
Second, eating food with more dietary fiber needs than fine food, so it will prolong the time of eating that food intake will decrease correspondingly.
Third, dietary fiber is characterized by absorbing water to increase the volume, so the size of food can swell to increase the sense of satiety and reduce food intake; in addition, it can promote intestinal peristalsis to take away some fat and cholesterol with excretion.
Forth, in the intestine, the gel formed by soluble dietary fiber can wrap in the surface of nutrient to impede their contact with digestive enzymes, so the absorption of saccharide will slow down and it also affects the amino acid metabolism and reduce the utilization of energy substances, therefore the body will reduce energy intake.
Thus, to eat food rich in dietary fiber helps weight loss. Fruta Planta
