Thirty lbs includes everything except my naked body. It includes everything I'm wearing, all food, 2 quarts (4 lbs) of water, etc.
There are very good equipment lists on this website that Charles has put together. I save a little weight by using a home made pack and not carrying a stove.
My homemade pack is in the Make Your Own section of this website and is listed as DJs Framepack. It weighs a total of 1 lb including waist belt, front bag, etc. It is a large pack and allows me to throw things in without much concern how I pack and stuff things.
