Use the following case study to answer questions
These questions require comprehension of various sections of the chapter to answer, but are placed together here to keep them together with the case study.Specifically, questions 95-97 test on "How are body weight and body composition assessed?"; 98-100 on "What determines energy expenditure?"; and 101-104 on "Does macronutrient distribution matter?"
Case Study: Jim, a 21-year-old, medium-frame 6'2" senior weighing in at 205 lbs is a very active varsity wrestler majoring in psychology.He is participating in a "Hydration Study" that includes the collection of the following data: body composition analysis utilizing the Bod Pod, food/beverage intake via dietary assessment questionnaire, urine sample, and analysis of saliva.The following data have been provided to assist in answering the questions.
Bod Pod Results:
59% body water
86.7% lean mass
13.3% fat mass
Reference Values for Bod Pod:
Risky (high body fat) = men: >30%; women: >40%
Excess fat = men: 21%-30%; women: 31%-40%
Moderately lean = men: 13%-20%; women: 23%-30%
Lean = men: 9%-12%; women: 19%-22%
Ultra lean = men: 5%-8%; women: 15%-18%
Risky (low body fat) = men: <5%; women: <15%
24-Hour Recall:
3540 kcalories
177 grams protein
118 grams fat
Males: EER = 662 - [9.53 x Age (y) ] + PA x [(15.91 x weight in kg) + (539.6 x height in m) ]
PA Values: Sedentary = 1.0, Low Active = 1.11, Active = 1.25, Very Active = 1.48
-Based on the Acceptable Macronutrient Distribution Range (AMDR) suggested for carbohydrates and Jim's daily energy intake from his 24-hour recall, calculate the range (in grams) of carbohydrates recommended for Jim each day

Question

Quizplus · Accepted Answer

To calculate the range of carbohydrates, we first need to calculate Jim's total energy expenditure (TEE). Using the provided formula, we get:

662 - [9.53 x 21 (Jim's age)] + 1.48 x [(15.91 x 93.2 kg) + (539.6 x 1.88 m)] = 3,992 kcal/day (rounded to the nearest whole number)

Based on the AMDR, carbohydrates should make up 45-65% of Jim's daily energy intake. We can calculate the range of carbohydrates as follows:

Minimum: 45% x 3,540 kcal/day ÷ 4 kcal/g = 398 g/day (rounded to the nearest whole number) 
Maximum: 65% x 3,540 kcal/day ÷ 4 kcal/g = 575 g/day (rounded to the nearest whole number)

Therefore, the range of recommended carbohydrates for Jim each day is 398-575 grams. Option B is the only answer choice within this range.
