# Basal Metabolic Rate (BMR)

The BMR Basal Metabolic Rate (BMR) as well as the Active Metabolic Rate (AMR) show us how many calories our body consumes in a day.

The difference between Basal and Active is that the former calculates the energy we need at rest, ie the calories our body needs to maintain its normal functions (Heart, Brain, etc.), while the latter calculates the energy that our body needs including physical activity.

The Basal Metabolic Rate is 75% (on average) of the calories we consume every day. On the contrary, the Active Metabolic Rhythm is based on the lifestyle we have (eg: sedentary, athletic, etc.).

Metabolic rhythms beyond physical exercise are proportional to a person's gender, weight, height, and age and are calculated using mathematical formulas.

The mathematical formula for calculating the Basal Metabolic Rate is as follows:

Women: basal metabolic rate = 655 + (9.6 x weight in kilograms) + (1.8 x height in centimeters) - (4.7 x age in years)
Men: basal metabolic rate = 66 + (13.7 x weight in kilograms) + (5 x height in centimeters) - (6.8 x age in years)

At the same time, to calculate your Active Metabolic Rate you must first select the type and frequency of your daily physical activity which is divided into 5 levels.

• Very Small - Rare Exercise BMR x 1.2
• Moderate - Exercise up to 3 times a week BMR x 1.375
• Intense - Exercise 3-5 times a week BMR x 1.55
• Daily - Exercise every day BMR x 1,725
• Athletic - Very intense exercise every day BMR x 1.9

This way you can easily calculate your body's daily energy needs in calories so that you know how much energy you need to consume to maintain, increase, or decrease your body weight.
