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 MacronutrienRange (AMDR) suggested for carbohydrates and Jim's daily energy intake from his 24-hour recall, calculate the range (in grams) ofor Jim each day.
