Look into Muscle Milk - they are a decent protein shake company, there product also contains fats, but when people hear the word fats they think they are going to put on mounds of weight - some fats are good for your body and will help you burn the stubborn fat around the gut so forth.

Cookies N' Cream is pimp juice for protein shakes - it even goes decent with water.

Alot of people use 2 or 3 shakes a day. Muscle Milk you can take 2 hours prior to a workout and it will put a good bit of protein and fat into your system to help you rebuild while ripping, and then you can take it after the workout to help regain energy and rebuild faster (add abit of REAL sugar to help it get into your system faster.) and for the 3rd shake some people take it before going to sleep to let the protein drip into your system while you sleep (mix with milk so it digest slow.) you can also mix the stuff with water to cut down on fat intake, tastes "OK" with water.
