To me the protein powders are satisfying. I use one called Naturade 100% Soy protein booster with 0 carbs mixed with flax seed meal as a cereal. And I use Biochem Ultimate Lo Carb Whey Powder for shakes with just 1gm/serving. Since I don't eat meat or eggs they bring my protein in my intake up and I like that. I have never felt that they stalled me.
