While true zero-calorie foods are a myth, some choices do give people the chance to eat as much as they want without the added concern of weight gain. As reported by Insider, these foods typically fall into one of two categories, non-starchy fruits or vegetables, and keep the calories low due to their high water and fiber counts.
The fruits and vegetables on this list are good sources of certain antioxidants, vitamins, and other nutrients a body needs to stay healthy. Since they aren’t high in protein, they can’t be the only foods in a person’s diet, but they do provide the option to supplement other healthy eating habits and ensure full satiation without a lot of calories.
