Negative Calorie Foods (No, this isn't Science Fiction)

     The year 2025, scientist in an effort to stop the widespread obesity have developed negative calorie foods.  Yes, foods that you eat and it takes more calories to digest them then the calories inside the food.  Wait, hold on, these foods already exist, yikes, and you mean we don't even have to wait till 2025 to have them?  Yep, the plain and simple fact is, there are foods that currently are "negative" Calorie.

     The term "negative calorie" might be the wrong way to term these foods, but basically these are foods that take more calories to digest than the calories that are in them.  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.  This is not a complete list, there are some other negative calorie foods, but this will give you a good starting point.  You can eat any of these foods in any quantity you want.  Just remember, this is the food plain, if you add butter, sugar, etc to the food it will no longer be a negative calorie food!
