Make a deal with the emotional eating monster that resides in the back of your mind! Whenever you are fighting it calm down work through the emotion and then make a deal that you have to do an extra workout or clean the whole house before you can have that craving. Don't sell yourself short though!
Think of the monster in you as a little child. If they have to do something they don't like to do to get what they want they are less discouraged to want it. Just make sure the deal doesn't leave you hanging and keep what you eat in check. Limit it to the portion size recommended or less.
