Caloric density refers to the number of calories in a specific weight or volume of food. Foods with high caloric density, like nuts and chocolate, provide more calories in a smaller portion, while low-caloric density foods, such as fruits and vegetables, offer fewer calories in larger portions. This concept helps individuals understand how to manage their energy intake. Understanding caloric density can aid in weight management and healthy eating. By choosing low-caloric density foods, people can feel fuller while consuming fewer calories, which may support weight loss or maintenance. Balancing high and low caloric density foods is key to a nutritious diet.
