A calorie is a unit of energy.In a nutritional sense, all types of food — whether they are fats, proteins, carbohydrates or sugars — are important sources of calories, which people need to live and function.

What should those calories be?
The official Dietary Reference Intakes (DRI) published by the National Academies of Sciences, Engineering and Medicine recommends that for an adult, 45 to 65 percent of calories should come from carbohydrates, 20 to 25 percent should come from fat and 10 to 35 percent should come from protein. Children need a higher proportion of fat, between 25 and 40 percent of their calories. No more than 25 percent of total calories should come from added sugars.
What are low-calorie foods?
Foods that are considered low-calorie have a low amount of calories relative to their serving size. Fruits and especially vegetables are usually relatively low in calories. For example, 2 cups of shredded romaine lettuce or spinach have 16 calories, a large stalk of celery has 10 calories, 1 large ear of corn has 123 calories, 1 cup of broccoli has 15 calories and an orange has 70 calories, according to the USDA Nutrition Database.
