BMR (Basal Metabolic Rate) is calculated using the Mifflin-St Jeor equation: for men (10 × weight + 6.25 × height - 5 × age + 5), for women (10 × weight + 6.25 × height - 5 × age - 161).
Sedentary (office job), lightly active (1-3 days exercise), moderately active (3-5 days), very active (6-7 days), and extra active (physical job + daily exercise).
Maintenance = calories to maintain current weight. Cutting = 500 calorie deficit for fat loss (~0.5 kg/week). Bulking = 300-500 surplus for muscle gain.
The basic calculator uses weight, height, age, and gender. For more precision based on body fat percentage, use the Katch-McArdle formula variant.
