calorie density

Calorie density refers to the number of calories a food contains relative to its weight or volume. Foods with high calorie density have many calories packed into a small amount, like fried foods or candies. Low calorie density foods have fewer calories for the same weight, such as fruits and vegetables. Understanding calorie density helps with weight management—choosing lower-density foods can help you feel full with fewer calories, while higher-density foods provide more calories in smaller portions. It’s a useful concept for making balanced dietary choices that support health and satiety.
