Detailed Description

• Basal Metabolic Rate (BMR):
  • BMR is the number of calories your body needs to maintain basic physiological functions (e.g., breathing, circulation) at rest.
  • Formula for Men:BMR=88.362+(13.397×Weight)+(4.799×Height)−(5.677×Age)BMR=88.362+(13.397×Weight)+(4.799×Height)−(5.677×Age)
  • Formula for Women:BMR=447.593+(9.247×Weight)+(3.098×Height)−(4.330×Age)BMR=447.593+(9.247×Weight)+(3.098×Height)−(4.330×Age)
• Total Daily Energy Expenditure (TDEE):
  • TDEE is the total number of calories you burn in a day, including physical activity.
  • Formula:TDEE=BMR×Activity LevelTDEE=BMR×Activity Level
  • Activity Levels:
    • Sedentary: 1.2 (little or no exercise)
    • Lightly active: 1.375 (light exercise/sports 1-3 days/week)
    • Moderately active: 1.55 (moderate exercise/sports 3-5 days/week)
    • Very active: 1.725 (hard exercise/sports 6-7 days/week)
    • Extra active: 1.9 (very hard exercise/sports & physical job)
• Example Calculation:
  • For a 30-year-old male, weighing 70 kg, height 175 cm, and moderately active:
    • BMR = 88.362+(13.397×70)+(4.799×175)−(5.677×30)≈166288.362+(13.397×70)+(4.799×175)−(5.677×30)≈1662 calories.
    • TDEE = 1662×1.55≈25761662×1.55≈2576 calories.
