Always Choose High-Fiber Grains over Processed Grains

We all know by now that white bread, white rice, and plain crackers contain a lot of empty calories and a lot less fiber than whole-grain breads, cereals, crackers, and rice. One of the quickest and healthiest ways to boost your fiber intake – and thereby your metabolism – is to substitute higher-fiber foods, such as whole-grain bread, crackers, or chips, brown rice, and whole-wheat pasta for lower-fiber foods, such as white bread, white rice, or plain crackers.
