I think people get images in their heads of what they look like. And it takes a lot to change those internal mental images. It works the other way, too; I never pictured myself as heavy as I eventually got.
Terrible book: This trip, I've had time to read some fiction, but I picked an absolutely awful book; The Mermaid Chair by Sue Monk Kidd. It started off terribly, but I wanted to see if it would get any better. It didn't.
