Chard, often known as Swiss chard, is a leafy green related to beets and spinach.

Chili peppers are another low-calorie food option if the bell pepper item piqued your interest.
Chili peppers have even fewer calories than sweet peppers do since they are far less sweet.
A cup of cucumber has only 16 calories, so it makes sense that they are used in place of higher-calorie foods like tortilla chips and crackers in many dishes.

The "grapefruit diet" has been around for a century, and its adherents swear by its sugar-, carbohydrate-, calorie-, and protein-reducing properties.
