I thoroughly disagree with some of the nutritional aspects of hodybuilding diets. While it is true- I do not eat much fruit, most of the carbs I (and any serious lifter) would eat is whole grains and starchy carbs that are unrefined, like sweet potatoes.
I eat 3500 - 4000 calories per day and bring in about 40-50g fiber daily. Thats twice as much as the average american. The stomach pokes because its full.
