How it works
Enter your age, gender, height, weight, and activity level. The calorie calculator uses the Mifflin-St Jeor equation to calculate your Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE) — the number of calories you need to maintain, lose, or gain weight.
Why use this tool?
Used by fitness enthusiasts, dietitians, and anyone starting a weight loss or muscle gain journey. Knowing your TDEE is the first step to a successful nutrition plan and calorie deficit diet.
