What is BMR? – BMR definition

A person burns calories continually throughout the day in order to sustain basic life functions, such as breathing, circulation, and digestion. BMR is a minimum number of calories required for basic functions at rest.

It is a measure of an organism’s capacity for growth, maintenance and reproduction. It also determines the rate at which an individual can burn calories, thus demonstrating an association with his or her body mass.

What are Calories and What do We Need Them For?

A calorie is a unit of energy. In nutrition, calories refer to the energy people get from the food and drink they consume, and the energy they use in physical activity.

Calories are listed in the nutritional information on all food packaging. Many weight loss programs center around reducing the intake of calories. One large kilocalorie (kcal) is the equivalent of 1,000 calories.

Keeping track of your calorie intake helps you better understand the amount of calories your body needs to lose, gain, or sustain a certain weight. Whatever your goal, knowing how many calories you are eating is key to getting the desired effect.
