Medicine
Basal Metabolic Rate Calculator
Estimate the calories your body burns at complete rest using the Mifflin-St Jeor equation, then multiply by an activity factor to get Total Daily Energy Expenditure. Use the resulting kcal/day as a baseline for diet planning.
Fitness
Daily Calorie Needs Calculator
Estimate total daily calorie needs (TDEE) by combining the revised Harris-Benedict BMR formula with an activity multiplier. The number to eat at for maintenance, subtract from for fat loss, or add to for muscle gain.
