🔥 Calorie Calculator

The calorie calculator estimates your daily energy needs based on your body metrics and activity level. Input parameters: • Gender, age • Height, weight • Activity level (sedentary / light / moderate / heavy / athlete) • Fitness goal (lose / maintain / gain) How it works: 1. Calculates Basal Metabolic Rate (BMR) using the Mifflin-St Jeor equation 2. Multiplies by activity factor for Total Daily Energy Expenditure (TDEE) 3. Adjusts based on goal (weight loss: -500 kcal, muscle gain: +300-500 kcal) Understanding the results: • BMR: calories burned at complete rest • TDEE: total daily calorie needs including activity • Target calories: adjusted intake based on your goal Common use cases: weight loss calorie tracking, muscle gain nutrition planning, dietary management reference.
