Answer 1

1. Age of the person -25years

Weight of the person is 198lbs = 198×0.45 = 89.1kg

Height of the person is - 5'8inch = 1.727m

His Physical activity - 1.11

EER - [662-(9.53× 25)] + PA(1.11) ×[(15.91×89.1)+ 539.6× 1.727)}

= [ 662- (238.25) ] + 1.11× [ (1417.581) + ( 931.8892)]

= 423.75 + 1.11 × 2349.47

= 423.7+ 2607.9

= 3031.6

2. BMI = BODY MASS INDEX

= WEIGHT IN KG / HEIGHT IN METERS SQUARE

= 89.1 / 1.727 × 1.727

= 89.1/ 2.98

= 29.8 kg / meter square

His BMI classification is Overweight

3. Calories required for this person according to his age ,gender , physical activity is 2400calories

Calories from CHO - 2400/4 = 600gm

4. Protein required by him is 0.8gm per kg

= 0.8× 89.1= 71.2 gm
