Kashi GoLean Original
160 calories, 10g fiber, 13g protein, 9g sugar
We love this cereal for its double whammy of protein and fiber. In fact, this Kashi classic leads the pack in protein per serving in this ranking, with a whopping 13g per cup. Pour a bowl of GoLean Original, and you'll also be rewarded with a flavorful blend of honey-touched puffs and crunchy twigs. The only drawback is that the cereal gets most of its protein from toasted soybeans, or soy grits, and some men may want to watch their soy intake.
