negative calorie foods

So I'm sure everyone knows about negative calorie fruits and vegetables, but I never knew about this until recently. I figured EVERYTHING had calories that you had to exercise off.

From a site:

"Negative calorie foods are foods, which use more calories to digest than the calories food actually contains! Calories from these foods are much harder for the body to use. In other words, the body has to work hard in order to extract calories from these foods. Even though a food may contain equal amount of calories, much less of these calories can possibly turn into fat in negative calorie foods as fewer calories are actually available to the body. This gives these foods a tremendous natural fat-burning advantage."

List:

Negative Calorie Vegetables
Asparagus Beet Root Broccoli Cabbage Carrot Cauliflower Celery	Chicory Hot Chili Cucumber Garden cress Garlic Green Beans	Lettuce Onion Radish Spinach Turnip Zucchini
Negative Calorie Fruits
Apple Blueberries Cantaloupe Cranberry Grapefruit	Honeydew Lemon/Lime Mango Orange Papaya Peach	Pineapple Raspberry Strawberry Tomato Tangerine Turnip Watermelon

Yay... I like most of these foods so it works for me. Today I sliced up cucumbers, apples, blueberries, and peaches and put them in a bowl to nibble on. They're aren't that filling but hey, if it keeps me from consuming real calories, I'm allll about it.
