What is the Fitness Calculator?
The Fitness Calculator is a comprehensive tool that analyzes your body metrics and calculates personalized fitness recommendations. It determines your daily caloric needs, macronutrient requirements, body composition, and provides workout/nutrition guidance based on your fitness goals and activity level.
Key Fitness Metrics:
• BMI (Body Mass Index): Weight / Height² - screening for weight categories
• BMR (Basal Metabolic Rate): Calories burned at rest using Harris-Benedict formula
• TDEE (Total Daily Energy Expenditure): Total calories burned daily = BMR × Activity Factor
• Body Fat %: Estimated using Deurenberg formula based on age, gender, BMI
• Macronutrients: Protein, carbs, fats distribution for fitness goals
Activity Level Multipliers:
• Sedentary: BMR × 1.2 (little to no exercise)
• Light: BMR × 1.375 (exercise 1-3 days/week)
• Moderate: BMR × 1.55 (exercise 3-5 days/week)
• Active: BMR × 1.725 (exercise 6-7 days/week)
• Very Active: BMR × 1.9 (intense daily exercise)
Fitness Goals & Macronutrient Targets:
• Maintain Weight: TDEE calories | Protein 1.6-2.2g/kg
• Lose Weight: TDEE - 500 cal | Protein 2.0-2.5g/kg (preserve muscle)
• Gain Muscle: TDEE + 300-500 cal | Protein 2.2-2.6g/kg (build muscle)
Macronutrient Ratios:
• Protein: Essential for muscle repair and growth (1.6-2.6g per kg body weight)
• Carbohydrates: Primary energy source for workouts (45-65% of calories)
• Fats: Essential hormones and absorption (20-35% of calories)
Body Fat Percentage Categories:
Men: Essential (2-5%) | Athletic (6-13%) | Fitness (14-17%) | Average (18-24%) | Obese (25%+)
Women: Essential (10-13%) | Athletic (14-20%) | Fitness (21-24%) | Average (25-31%) | Obese (32%+)
BMI Categories:
• Underweight: BMI < 18.5
• Normal: BMI 18.5-24.9
• Overweight: BMI 25.0-29.9
• Obese: BMI ≥ 30
Fitness Tips:
• Combine strength training 2-3x/week with cardio 150+ minutes
• Adjust calorie intake based on weekly progress
• Track food intake to meet macronutrient targets
• Stay consistent with exercise and nutrition
• Get adequate sleep (7-9 hours) for recovery
