A Calories Calculator uses the Mifflin-St Jeor equation to estimate your Basal Metabolic Rate (BMR) and total daily energy expenditure (TDEE). It then adjusts these numbers based on your fitness goals to provide personalized calorie and macronutrient recommendations.

Beyond simple calorie counting, this tool provides detailed macronutrient breakdowns showing exactly how many grams of protein, carbs, and fat you should consume daily. This science-based approach ensures you're not just eating the right amount, but also the right balance of nutrients.
