Calculators

# BMI
bmi = weight_kg / (height_m ** 2)
# Categories: <18.5 underweight, 18.5-24.9 normal, 25-29.9 overweight, 30+ obese

# TDEE (Harris-Benedict)
bmr_male = 88.362 + (13.397 * weight_kg) + (4.799 * height_cm) - (5.677 * age)
bmr_female = 447.593 + (9.247 * weight_kg) + (3.098 * height_cm) - (4.330 * age)
# Activity multiplier: sedentary 1.2, light 1.375, moderate 1.55, active 1.725
