20 Zero Calorie Foods to Help You Slim Down

The theory behind zero calorie or negative calorie foods is that they contain such a scant amount of calories that the energy you expend eating them cancels out their calories. In essence the bottom line is that you don’t take on any excess calories, and in some instances you end up burning calories as you eat them. Whether or not this is an accurate statement, it’s clear that the following foods have such a slight caloric load they won’t put a dent in your daily total.

Each of these foods has fewer than 50 calories per 100 gram serving. Considering that chicken breast has 172 calories in that same portion size and is considered a low calorie food, it’s clear to see these foods rank very low in terms of calories.

1. Celery
Celery is a food that when you eat it you don’t really feel like you’re eating anything, so it’s not a total shocker to find out that it has essentially zero calories. What you’ll typically see is celery with peanut butter or cream-based fillings inside of it, and you’ll want to avoid those if you are keeping track of calories, as they can swing it back the other way quite quickly.
