Daily Calorie Calculator: Comprehensive Guide to Personal Nutrition Needs
Accurately calculate your BMR and daily calorie requirements using the Mifflin-St Jeor equation. Learn weight management strategies, macronutrient distribution, and adjust for activity level using our Daily Calorie Calculator.
The Science of Calorie Needs
Daily Calorie Requirement is determined by your Basal Metabolic Rate (BMR) and Physical Activity Level (PAL). While the average is around 2500 kcal for adult men and 2000 kcal for women, individual needs can vary by about ±500 kcal.
Mifflin-St Jeor Formula
Men: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age) + 5
Women: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age) - 161
Practical Examples
Example 1: Active Young Male
Age 30, 80 kg, 180 cm, exercises 5 times per week
TDEE = BMR (approx. 1800 kcal) × 1.55 = 2790 kcal
Example 2: Pregnant Woman
Second Trimester: Base Calories + 340 kcal
Third Trimester: Base Calories + 452 kcal
