Jim Katsoulis argues that being thin is a skill, not just knowledge. Like learning piano, you can't think your way there. You have to practice thin-person habits, thoughts, and choices until they become automatic.

You don't know how to be thin if you're not thin. You have some vague ideas of what you should do, but you don't know how to do it regularly. It's like saying, "I know how to play the piano. I just gotta practice a lot and hit the right keys." Well, that's not knowing how to play the piano. So the secret to becoming thin is to realize you have to practice it. You have to get good at being thin, eating like a thin person, thinking like a thin person, living like a thin person. And it requires practice in order to make that happen.
