Wives Tales that are the Real Deal #1: Celery

We've all heard these old wives' tales, but did you know that some of them are actually true? We're going to take a look at a few, starting with: Celery burns more calories than it provides. Awesomely enough, this one is true. You see, a stick of celery gives you about 5 calories, but it takes more energy for your body to break it down with stomach acid, pass it into your digestive tract, absorb the nutrients, and excrete the waste products.

  • Grapefruits
  • Lemons
  • Apples
  • Limes
  • Broccoli
  • Cabbage
  • Lettuce
These foods are all fairly low in calories, but they take more energy to digest than they provide. As a bonus, the foods are all rich in enzymes that aid in digestion. When the enzymes are absorbed, they facilitate the digestion of other foods. Let's Get Technical: The only thing that can actually be considered "negative-calorie" is ice water. Ice water contains 0 calories, but your body has to burn energy to warm it to body temperature.
