Male = 66+(13.7x55)+(5x178)-(6.8x19)
= 66+753.5+890-129.2
= 1,580.3
Medium exercise or sport 3-5 days/wk x 1.55
Overall energy
Basal Metabolism 1,580.3
Physical Activity 1.55
Energy need = 1580.3x1.55 = 2449.5
Specific Dynamic Action = 245
Total energy needed = 2694.5

CHO-containing food 55% = 2694.5×0.55 = 1481.98
Food-fat 30% = 2694.5×0.30 = 808.35
Protein 15% = 2694.5×0.15 = 404.18
Energy values of foods
CHO 4 kcal/g or 17 kj/g
Fat 9 kcal/g or 38 kj/g
Protein 4 kcal/g or 17 kj/g
CHO-containing food = 1481.98/4 = 370.495 g
Food-fat = 536.66/9 = 59.63 g
Protein = 268.33/4 = 67.08 g
