Question

2. Rogelio is 5'7" tall and currently weighs 138 lbs. His usual body weight (UBW) for the past 5 years has been around 159 lbs, but due to an illness he recently lost weight. Complete the following calculations. a. IBW = 50 + (2x3x7)= 145.72 lbs b. IBW + 10% = 145.72 +/- 10/100 x 145.72= 131.15 to 160.29 c. % upper IBW = 145.72-138= 7.725/145.72 x 100=5.3% d. % UBW = 138/159 x 100= 86.79% e. Using 25 kcals/kg, calculate Rogelio's energy requirements. Using appropriate AMDR ranges, calculate CHO, protein, and fat kcals and grams. KCALS CHO: PRO: FAT:

just e please!

Answer 1

Provided information:

Weight in pounds= 138 lbs

= 138*0.45             (1 pound = 0.45 kg)

= 62.1 kg

Energy required per kg of body weight = 25 kcals

Total energy required in kcals= energy required per kg of body weight x total body weight

= 62.1 x 25

= 1552.5 kcals

AMDR (Acceptable Macronutrient Distribution Ranges) for adults are: 45-65 % carbohydrates, 20-35% fats, 10-35% protein.

Taking the AMDR as 45 % energy from carbohydrates, 20% from fats, and 35% protein.

Carbohydrates = 45/100 *1552.5

=698.6 kcal

Protein = 35/100*1552.5

= 543.3 kcal

Fats =20/100*1552.5

=310.5 kcal

Content in grams:

Energy obtained from 1 gram of carbohydrates = 4 kcal

Energy obtained from 1 gram of proteins = 4 kcal

Energy obtained from 1 gram of fats = 9 kcal

Carbohydrate content = total calories obtained/ per gram calories

= 698/4

= 174 gram

Protein content = total calories obtained/ per gram calories

= 543/4

= 135 gram

Fat content = total calories obtained/ per gram calories

= 310/9

=34.5 gram
