Body Mass Index is a simple calculation using a person's height and weight. The formula is BMI = kg/m2 where kg is a person's weight in kilogram and m2 is their height in metres squared. A BMI of less than 18.5 means that a person is underweight. A BMI of 25.0 or more is overweight, while the healthy range is 18.5 to 24.9.
What is BMR?
The The Mifflin-St. Jeor BMR Equation - Basal metabolic rate (BMR) is often used Interchangably with resting metabolic rate (RMR). While BMR is a minimum number of calories required for basic functions at rest, RMR - also called resting energy expenditure (REE) - is the number of calories that your body burns while it's at rest.
What is TDDE?
The Mittlin-St. Jeor TDEE Equation is calculated by adding four numbers together: basal metabolic rate, thermic effect of feeding, exercise energy expenditure, and non- exercise activity thermogenesis. The calculation in this application is for Sedentary Activity (little to no exercise + work a desk job).
