Saturated fats are particularly implicated in raising LDL levels, which increases the risk of developing atherosclerosis, heart attack, and stroke. The liver is constantly trying to clear out the bad cholesterol by dumping it into the intestines. Sufficient amounts of fiber like chitosan dispose of this cholesterol waste rather than letting the body reabsorb it back into the bloodstream. Low levels of fiber not only raise cholesterol levels, but also add to the toxic stress on the liver. The same dietary factors in developing obesity, namely high intake of fat and cholesterol and low fiber intake, are considered to influence the formation of cholesterol gallstones.
Obesity also leads to osteoarthritis because of the stress of excess weight on the body s joints.
Eating a low fat, high fiber diet will produce some weight loss even in normal weight subjects. The reason for this may well be the balance between fullness and satiety. It is a proven fact that one can easily eat an excess of fat before feeling full or satisfied. Increasing fiber intake helps an individual feel full and avoid overeating. This translates to a 150 pound person losing 12 pounds in one month.
