Mike has some great advice.
Every body responds to carb/fat/pro differently and you'll have to experiment a bit to see what works for you. I think it is very important to eat good, real food that you enjoy and that keeps you satisfied. You will do much better in the long run that way.
Really, if you are running a calorie deficeit you will eventually lose weight anyway (for instance the fellow who lost 25 pounds eating Twinkies and Hostess Cup cakes, while keeping a calorie deficeit. BUT, our goal is weight loss with good nutrition.
Personally, I shoot for a 40/30/30 mix, which I've since found out is what the "Zone Diet" recommends. If I'm one way or the other, I don't despair--these are only guidelines.
Anyway, welcome and keep up the good work.
