Brenda Watson, the guru of healthy digestion and detoxification, has written a new diet book that says fiber is the key to weight loss.

"The Fiber35 Diet: Nature's Weight Loss Secret" explains how 35 grams of fiber per day can help you lose weight, and help prevent the diseases that cut life short.

Watson says fiber fills you up and suppresses your appetite, allows you to eat more food without high calories and slows the body's carbohydrate conversion to sugar, which supports blood glucose stability that helps us lose weight.

"For every gram of fiber you consume, you don't absorb seven calories," Watson told Dan Vierria of McClatchy Newspapers. "That's 245 calories a day (eating 35 grams of fiber per day). Doing nothing else, you'll lose 2 pounds in a month."
