The effect of dietary fiber supplementation in man. I. Modification of eating habits.
Six subjects were studied for an 8-week period that consisted of a 3-week control period, followed by a 3-week period during which their daily diets were supplemented with 3 oz of a  high fiber breakfast food, All-bran, and a final 2 weeks on their regular diet. Daily diet records of food intake were recorded and analyzed for seven dietary constituents; carbohydrates, proteins, fats, cholesterol, fiber, alcohol, and total calories. The most significant change in eating behavior due to the fiber food supplementation was a decrease in eating eggs, butter, and breakfast meats. These foods were most often replaced because all six subjects chose to eat the major portion of All-bran during breakfast. An increase in milk and fruit also occurred during the supplemented feeding. These particular foods were added to make All-bran more palatable and served to increase carbohydrate and protein intake. Five subjects added the supplement to the between meal-time intake and thus caused an increase in total daily caloric intake. At lunch and dinner few foods were altered with no particular pattern of substitution. Notwithstanding the knowledge that increased fiber content may have beneficial effects, none of the subjects modified his eating behavior to include even 1 oz of a high fiber food daily after the experimental period was concluded. Thus behavior modification by forced diet intake of a high fiber breakfast food resulted in definite diet pattern changes that did not persist following the experimental period.
