The idea behind zero calorie foods is that they require more calories to chew and eat than they contain. Thus, you can eat them and still create a calorie deficit for weight loss. Sound too good to be true? The experts seem to be a bit divided on the topic, so that leaves it up to you to learn what you can and decide for yourself. The good news is that most foods that are considered zero calories are actually pretty healthy so they make a great food choice, even if they aren’t burning more calories than they contain. Here’s what you should know.

1. What’s the Science?

That being said, these foods are generally nutritious choices so eating them shouldn’t be an issue.
