    Study Notes

    Energy Requirement

    • Energy intake is the amount of calories contained in the diet.
    • Energy expenditure is the sum of energy consumed by the body for physiological and biochemical functions (internal) and for physical activity (external work).

    Estimating Energy Intake

    • Layman: 25-30 kcal/kg/day
    • Active: 30-35 kcal/kg/day
    • Very active: 35-40 kcal/kg/day
    • Ultra active: 40-60 kcal/kg/day

    Energy Intake Based on Body Weight

    • 60 kg: 2400 kcal/day, 108g protein, 480g carbohydrates
    • 65 kg: 2600 kcal/day, 117g protein, 520g carbohydrates
    • 70 kg: 2800 kcal/day, 126g protein, 560g carbohydrates
    • 75 kg: 3000 kcal/day, 135g protein, 600g carbohydrates
    • 80 kg: 3200 kcal/day, 144g protein, 640g carbohydrates

    Nutrient Used During Exercise

    • Energy in food is measured in calories (kcal)
    • Calorie conversion from nutrients:
      • CHO = 4 kcal/g
      • Fat = 9 kcal/g
      • Protein = 4 kcal/g
      • Alcohol = 7 kcal/g

    Energy Expenditure

    • The sum of energy consumed by the body for physiological and biochemical functions (internal) and for physical activity (external work)
    • Components of energy expenditure:
      • Basal metabolic rate (BMR)
      • Thermic effect of food (TEF)
      • Thermic effect of activity (TEA)
      • Non-exercise activity thermogenesis (NEAT)

    Estimating Energy Expenditure

    • BMR x PAL = kcal
    • BMR: 60-70% of total energy expenditure
    • Estimating BMR for Malaysian:
      • Male (18-30 years): 0.0550(w) + 2.480
      • Male (30-60 years): 0.0432(w) + 3.112
      • Female (18-30 years): 0.0535(w) + 1.994
      • Female (30-60 years): 0.0539(w) + 2.147
    • Harris-Benedict Equation:
      • For men: 66.5 + 13.8(weight in kg) + 5(height in cm) - 6.8(age in years)
      • For women: 655.1 + 9.6(weight in kg) + 1.8(height in cm) - 4.7(age in years)

    Resting Metabolic Rate (RMR)

    • Represents BMR plus a small amount of additional energy expenditure associated with eating and previous muscular activity
    • RER tends to be 10% greater than BMR

    Thermic Effect of Food (TEF)

    • 5-10% of energy intake
    • Process of food digestion and absorption requires energy and produces heat
