Diet tip: let your dog lick your plate

It's funny; I actually do this but I never thought of it as a diet tip until I saw it as a comment on a New York Times blog post.

"I have my dog lick my plate when I'm done eating, which really helps me stop and think about how badly I want seconds (which would require me to get up and get another plate). Just be careful- one time I let my dog lick my ice cream bowl then went and got seconds, only realizing after that I forgot to get a new bowl!"
