Energy is measured in calories. Calories in nutrition relate to the energy that humans obtain from the food and liquids they consume as well as the energy they expend when engaging in physical activity.

All food packaging contains nutritional information that includes a calorie count. The main focus of many weight loss strategies is calorie restriction.

In addition to discussing how the body uses energy, this MNT Knowledge Center article focuses on the calories included in food and beverages. MNT discusses the definition of a calorie, the number of calories that an adult needs daily, and healthy ways to consume calories.

Fast fact on calories 

The health of humans depends on calories. The secret is getting the appropriate dosage.
Depending on their age, sex, size, and degree of exercise, each person needs a different quantity of energy every day.
Fast food accounts for more than 11% of daily calories consumed in the United States.
Foods with lots of energy but few nutrients are empty calories.

What are calories?

There are two types of calories exist:

The amount of energy needed to increase the temperature of 1 gram (g) of water by 1 degree Celsius (o C) is known as a tiny calorie (cal).
The amount of energy needed to raise one kilogram (kg) of water by one degree Celsius is known as a big calorie (kcal). It is also referred to as a calorie.
1,000 calories make up 1 kcal.

Daily requirement

The United States government states that the average man needs 2,700 kcal per day and the average woman needs 2,200 kcal per day.

Not everybody needs the same number of calories each day. People have different metabolisms that burn energy at different rates, and some people have more active lifestyles than others.

The recommended intake of calories per day depends on several factors, including:

  • overall general health
  • physical activity demands
  • sex
  • weight
  • height
  • body shape
