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%

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
