Forget What You've Heard About 'Negative Calorie' Foods

The only reason you ever ate celery might be gone.

With modern lives becoming increasingly sedentary, it has never been more important to regulate calorie intake in order to maintain a healthy weight. Our bodies use calories in order to chew and digest food, so some people have tried to hack the diet system by eating "zero calorie foods." That is, they eat foods that have so few calories, they believe it will burn more calories to chew and digest them than the body takes in from eating it. 

Some of these foods include celery, black beans, mushrooms, chives, apples, and carrots. Of course, these are healthy foods that are a great choice for a low-calorie diet. 

But are they really "negative-calorie" or is it all a gimmick?

In a recent video, SciShow tackled the topic and used science to explain why negative-calorie foods really aren't a thing. The heart of why this myth isn't true is because not all foods take the same amount of energy to break down. The amount of effort the body uses to break the food down is directly related to how nutrient-dense the food itself is.
