Basal Metabolic Rate (BMR) is the amount of energy expended while at rest in a neutrally temperate environment, in the post-absorptive state. The Mifflin-St Jeor Equation is a widely accepted method to calculate BMR, considering it more accurate than older formulas for modern populations.
For men: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) + 5
For women: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) - 161
Pros:
Cons:
The preference for the Mifflin-St Jeor equation over others like the Harris-Benedict equation or the Katch-McArdle formula is due to its accuracy and simplicity, making it suitable for general dietary planning and weight management.
