How many calories is that? Doesn't seem like many. Try to eat some fruits and vegetables if you can. Oatmeal is a great source of calories...it's good for cholesterol also, I think. Remember, plain whey protein shakes do NOT make a good meal replacement. Good that you get it post workout and first thing in the morning though. Try oatmeal along with your shake in the morning.

Go ahead and add the multivitamin in. Don't get a one-a-day. Get something that you take at least twice a day. And fish oil is cheap...
