🔬 Methodology

This calculator uses a synthesis model averaging the three most validated equations for athletes, reducing individual equation bias.

Synthesis Model (Recommended)

Averages: Ten-Haaf (2014), Mifflin-St Jeor (1990), and Harris-Benedict (1984)

🏅 Ten-Haaf (2014) — Best for Athletes

REE = 11.936×weight(kg) + 587.728×height(m) − 8.129×age + 191.027×sex(M=1,F=0) + 29.279
Precision: 80.2% within ±10% of measured (O'Neill et al., 2023) Ten Haaf T, Weijs PJM. PLoS ONE 2014;9(10):e108460

✅ Mifflin-St Jeor (1990)

Males: 10×weight + 6.25×height − 5×age + 5 | Females: 10×weight + 6.25×height − 5×age − 161
Mifflin MD et al. Am J Clin Nutr. 1990;51(2):241-247

📚 Harris-Benedict (1984)

Males: 88.362 + 13.397×weight + 4.799×height − 5.677×age
