Negative Calorie Foods

     Okay, so what's negative calorie foods?  How can a food be a negative calorie?  Yes, I know you're looking at me a little odd at the moment, but let me explain why some foods are negative calories.  All food has calories, that goes without say, so saying these foods are negative calorie sounds impossible, right?  Well, these are foods that take up more caloric energy to digest then the calories that are in them.  Your body has to expend energy in order to digest and absorb foods, in fact, 10% of your daily caloric intake is used to process foods in your body.  So these "negative" calorie foods are foods that take more calories to digest then actual calories in the item of food.  Here is a brief list of negative calorie foods.  You can basically eat these items in any quantity you want during the day...remember though, this is for the raw version of the food, adding butter, etc, to any of these things will eliminate the negative calorie effect.
