Negative Calorie Foods are foods that require more calories to digest than are in the actual food. Cool, huh? You can eat the following foods in (almost) unlimited quantities and still not gain weight!

The following are foods that I consider to be "safe," or at least not all that bad.

Pria Powerbars (all flavors) - 110 cals, lots of vitamins and minerals, plus they give you energy.
Diet Sodas - NO CALORIES!!!
Good Humor Lowfat Fudgecicles - 45 cals! Great for releaving chocolate cravings.
Sugar-Free Jell-O - I love this stuff. Only 10 cals per serving.
Green Tea - No speakable calories, but it helps boost metabolism and flush out toxins.
Everlasting Gobstoppers - 9 of these have only 50 calories. Since they last so long, you can spread them out over an entire day!
Chicken bullion instant soup cubes - Only 5 cals per cube, which makes one cup of soup to keep you full.
Puffed Rice Cereal - Kashi makes a good one with 70 cals per cup. Tasty and high-fiber, too.
Nonfat Soy Milk - 70 cals, 0 grams of fat per serving. Compare to 90 cals per serving of nonfat / skim cow's milk.
