Eat to stay alive

I cant be the only who loves food? I got to have a lovely meal this weekend at dukes restaurant. It was decadent and quite filling to my surprise. So what does food have to do with physics? This week we are talking about energy. Food essentially gives all of us energy. If you don't know what its called it's calories, which are tiny people who sew our clothes tighter every night. But really calories is a measure of how much "energy" we are intaking. If you wanted to convert your calories into energy measurements, 1 calorie is equal to about 4.1855 joules.
