Have you ever heard of the part of your brain that helps you with self control? In the front is where it resides I believe- no food means less self control (basically you get hangry) and less self control means conflict- but all can be fixed with a little snack or a tv dinner.
Don't know if it's 100% true because I'm not the brightest of bulbs in the pack, so take the brain bits with a grain of salt if you would.
