Macro & Calorie Calculator

This Calorie Calculator is based on the Mifflin-St Jeor Formula which calculates Basal Metabolic Rate (BMR), and its results are based on an estimated average. The Basal Metabolic Rate is the amount of energy expended per day at rest.

For men:
BMR = (4.536 x weight in LBS) + (15.88  x height in INCHES) - (5 x age)+5 x Activity Level

For women:
BMR = (4.536 x weight in LBS) + (15.88  x height in INCHES) - (5 x age)-161 x Activity Level
