What is the Mifflin St Jeor Equation?

Mifflin St Jeor is arguably the best-known Basal Metabolic Rate calculating equation. It uses weight, height, age, and even gender to provide the most accurate MBR estimate you can possibly get, enabling tailored fitness plans.

How does a resting metabolic rate calculator work?

Just like our BMR tool, a resting metabolic rate calculator calculated all of the calories burned while on rest. You just have to input your details, and it utilizes the Mifflin St Jeor formula to estimate your daily caloric needs.
