mate, seriously, I hate to say this...but I dont understand why people start to do anything (immaterial what you want to do, in this case loose fat) without properly learning and understanding the mechanics behinds weight loss.
As I said, there are alot of articles in the stickies and google for even more. Then if you dont understand, you can ask for our opinion, remember what we say is not gospel, its just from experience and readings....
its really bad and and times could be dangerous with no proper readings you start something...
anyways, do read and read and read, and understand what you are reading, see where you stand now and then, set a proper goal.
if you have done your reading you wont be asking these silly questions.
calories, mentioned on the labels and as for raw or cooked food, you could check it out at

ANd yes, muscles needs protein, and if you dont work and feed our muscles, you are going to loose it as part of slimming program, end of the day you will be skinnyfat and not lean.
