The truth about “negative calorie” foods. A coworker of mine keeps going on and on about her “negative calorie” diet. I don’t see how food can have fewer than zero calories, but whatever she’s eating, it’s working-she lost 20 pounds fast! Is it too good to be true?
The idea of a negative-calorie diet may sound strange, but it’s actually a real phenomenon that does facilitate weight loss. That’s because these diets are rich in foods so low in calories that the body expends more calories digesting a food than that food itself contains. For example, the body burns 80 calories digesting a 25-calorie piece of broccoli, leaving you with negative 55 calories. To enjoy the benefits, nosh on negative-calorie foods like asparagus, apples, carrots, cucumbers, onions, oranges, papaya, pineapple and spinach.
