ChiliTri BMR & Macro Calculator for Athlete Nutrition

Even when resting your body burns calories by performing basic functions to sustain life like breathing, circulation, nutrient processing and cell production. 

Basal Metabolic Rate (BMR) is the number of calories your body needs to accomplish its most basic (basal) life-sustaining functions.

Why is BMR important for athletes?

BMR is a useful first step for you to determine how many Calories they should be consuming each day. Once you calculate your BMR, you can use it to more accurately account for all the Calories you as an athlete burns each day, both while exercising and at rest.

You can use the calculator below to work out your personal BMR and from there make sure you are eating the right amount of calories. At the bottom of the calculator is a indication of your BMR calorie needs and minimum macro nutrient requirements (Protein, Fat and Carbohydrates). 

Learn how to use your BMR and Macro calculation in the Blog.

During training optimising your macronutrient intake, not only the quantity but the timing, can be the difference between a wasted workout versus hitting your desired gains in power, speed or endurance. Misjudging your nutrition on race day could be a disaster and you could “bonk”, miss out on your PB, get cramp or even DNF.

A good starting point for your nutrition plan is to calculate your BMR.
