The American Council on Science and Health (New York) says it is uncertain whether dietary fiber has specific benefits in weight control. However, it is generally felt that people with diets rich in fiber diets are less likely to be obese. Some of the mechanisms through which dietary fiber may impact weight include reduced energy intake, flattening blood glucose response after carbohydrate ingestion and increased satiety, among many others. (See the Quaker Oats' website below.)
A number of companies both enhance the dietary fiber and reduce the fat content in their products. For example, Brownberry Bakery Light, 100% Whole Wheat Bread introduced in 2002 by Arnold Foods (Totowa, N.J.), parent company George Weston Bakeries Inc., notes it has 40 calories per slice (1/3 fewer calories than regular wheat bread). It also notes that it is “an excellent source of fiber,” which is derived from its whole wheat flour, soy fiber and wheat bran.
