Burning Calories?

They say that you can burn calories by eating celery. If that is so, then I wonder how many calories I burned this week eating Jewish Apple Cake, M&Ms, granola bars, peanut butter (my personal favorite), a ton of stew, Cinnamon Life Cereal, and a cookie the size of my head (my other personal favorite). I should have lost at least 10 pounds; or is it the other way around considering lifting these to my mouth is the only form of physical exertion I applied this week?
