I think it depends on several variables...on how much protein you are consuming on a daily basis before the shakes, what your goals are, and what your current weight is. If you are lifting heavy and your goal is to gain muscle, two quality (whey or soy) protein shakes at roughly 24 grams of protein each (if you are mixing only with water) will help conserve, repair and grow muscle. From everything I've read, one gram per pound of body weight is considered appropriate for women bodybuilders and .50 to .75 grams for those that aren't competing just trying to be the best they can be. My morning ritual is one scoop (24 grams) of whey protein with water at about 6:30 am. I'll have another shake directly after my daily workout, when mixed with water that's just 120 calories. If I'm mountainbiking and ride hard over two hours, when I get home I have another shake before I go to bed, this one with milk to break down slower over night when I sleep. I don't think you should be afraid of a high-quality protein scoop a couple of times a day. It will provide you with quality amino acids and the side benefits are good skin, hair and nails! Not to mention repairing those hard-worked muscles.
I'm trying to reduce the belly bulge. I'm trying to clean up the eating but I have a long way to go. I'm trying to reduce the carb intake so I'll making them with water. Thanks for the information.
