Which equation is commonly used to estimate basal metabolic rate?

Explanation:
Estimating basal metabolic rate relies on predicting the energy your body needs at rest using simple body measurements. The Mifflin-St Jeor equation is widely used today because it provides accurate estimates across a broad range of body sizes and compositions. It uses weight, height, age, and sex with separate formulas for men and women: for men, BMR = 10 × weight(kg) + 6.25 × height(cm) − 5 × age(y) + 5; for women, BMR = 10 × weight + 6.25 × height − 5 × age − 161. This formula was developed from a large contemporary sample and validated against measured BMR, which helps explain why it’s favored in clinical nutrition and fitness settings. In practice, you multiply the BMR by an activity factor to estimate total daily energy expenditure. Other equations exist but are older or less consistent across modern populations. Harris-Benedict and Schofield were developed earlier and can over- or under-estimate for today’s diverse bodies, while Cunningham focuses on lean body mass and is more specialized for athletes.
