I found this tool quite helpful. It's chock-full of common sense, and it has some great spreadsheets.

The Hacker's Diet

(Is this the right forum for posting this?? I don't know)

thanks for the link! i really liked this book. it validated everything i think about dieting and i got some useful new information from it too. i especially liked the new concept for weighing yourself. now i don't feel so bad when i'm up (or have unrealistic glee when i'm down).

A good site and seems not to be selling anything, unless I'm missin' it.
