Calorie requirement for a 60 kg sedentary man
• Calorie required for BMR = 60 x 24 (since BMR for an adult male is ~ 24 Kcal/kg/day)
= 1440 kcal/day
• Calorie required for physical activity:
Sedentary work 30% of BMR
Moderate work 40% of BMR
Heavy work 50% of BMR
So, for a 60kg sedentary worker = 30 x 1440
100
= 432 kcal
Total energy = 1440 + 432 = 1872 kcal
• Calorie needed for Specific Dynamic action = 10% of Total energy
= 10 x 1872
100
= 187.2 kcal
• Total calorie requirement = 1872 + 187.2
= 2059 kcal/day
~ 2050 kcal/day (value nearest to multiples of 50)
Converting energy requirement into proximate principles:
Total calorie requirement for a 60 kg sedentary man = 2050 kcal/day
Protein (RDA = 1g/kg) 60 x 1 = 60 g 60g/day
60 x 4 = 240 kcal
Fat (RDA = 20% of total 2050 – 240 = 1810 kcal 40 g/day
energy) 1810 x 20% = 362 Kcal
362/9 = 40g
Carbohydrates 1810 – 362 = 1448 kcal 362 g/day
1448/4 = 362 g
