## Calories, Calorie Counting Basics
A calorie is a unit of energy used to measure the energy content of food. The kilocalorie (kcal) is another commonly used unit of energy, and it is equal to 1,000 calories.

How Many Calories Should I Eat?
The number of calories you should eat each day depends on several factors, including your age, sex, activity level, and weight loss goals. However, the Dietary Guidelines for Americans recommend that adults consume between 1,600 and 2,400 calories per day.

What is Calorie Density?
Calorie density is a measure of how many calories are contained in a given volume of food. Foods with a high calorie density are more likely to cause weight gain than foods with a low calorie density.
