High-calorie foods mainly refer to foods with high contents of fat, sugar and protein, especially the first two categories. Usually, the calories of food are inversely proportional to the water content, and directly proportional to the sugar and fat content. Foods with high calories can be divided into high-fat foods, high-sugar foods and high-protein foods.
