Question

Case Study:

Chloe is a 21 year old, female student athlete. She is 5’7” and weighs 130 pounds. Chloe is on the college cross-country team. She tries to eat plenty of grains and fruits to get the carbohydrates needed for her high level of physical activity. She eats 3 meals a day and a snack in the evenings. Chloe is a fairly strict vegetarian, typically including foods consistent with a lactovegetarian or lacto-ovo-vegetarian depending on the season and her current mood. She also avoids alcohol and various forms of tobacco.

Diet analysis revealed Chloe’s caloric intake for three days was 6500 calories (approximately 2200 kcal per day) and she's maintaining her current body weight. She averages 330 grams of carbohydrate, 61 grams of fat, and 83 grams of protein per day, according to her diet record. Her vitamin B12 intake averaged 0.24 μg/day (recommendation for B12 is 2.4 μg/day). A typical day for Chloe would include eating cheese sticks and a glass of orange juice for breakfast; a slice of bread with peanut butter, apple, bag of pretzels, and raspberry iced tea for lunch; spaghetti with marinara sauce, garlic bread, salad, and a glass of milk for dinner; and an orange for an evening snack. This semester, Chloe feels tired more often and almost always has to take a sweatshirt to class to keep warm. Chloe is also unable to concentrate well.

1) Based on her BMI and body composition, how would you classify her weight? Are you able to make the same classification based on each or do they differ?

2) After reviewing Chloe’s typical dietary intake and her symptoms [fatigue/inability to concentrate/difficulty regulating body temperature], what nutrient (commonly deficient in female athletes) do you think she is lacking? List 5 specific dietary changes or substitutions you would suggest for her to improve her intake of this nutrient.

3) Since Chloe is a collegiate level athlete, we can assume her activity level is “very active”. What is her EER?

Answer 1

1.BMI of chole is 20.36

According to classification of weight:

Normal

2.chole is lacking vitamin B 12.

To increase the amount of vitamin B12 in your diet, eat more of foods that contain it, such as:
Beef, liver, and chicken.
Fish and shellfish such as trout, salmon, tuna fish, and clams.
Fortified breakfast cereal.
Low-fat milk, yogurt, and cheese.
Eggs.

For vitamin B12 deficiency: Vitamin B12 doses of 300-10,000 mcg daily have been used. However, some evidence suggests that the most effective oral dose is between 647-1032 mcg daily.

3.EER of an active female 21 years old with height 5'7 inches ,weight 130 lbs is:

Formula of EER of female-

EER= 354-(6.91×age(yr)+PA×(9.36×weight(kg))+726×height (meters))

PA of an active female is 1.27

Weight is 130 pounds

Convert into Kg's

130 pounds = 58.69kgs

Height 5'7 convert into meters

5'7 inches= 1.70 meters.

EER=354-(6.91×21)+1.27(9.36×58.69)+(726×1.70)

EER=354-(145.11)+1.27×(549.33)+(1234.2)

EER=208.89+1.27×1783.53

EER=208.89+2265.08

EER=2473.97KCAL.
