Activity 3.2.5: PLTW Nutrition – Client Report for Trisha Knowles Client Name: Trisha Knowles Health History (including any specific health goals): Trisha Knowles is a 19-year-old sophomore majoring in biology. Trisha exercises regularly, sometimes twice a day. She has been a vegetarian for just under a year and she recently eliminated almost all carbohydrates from her diet. Trisha does eat dairy and occasionally, she eats seafood. She packs small meals to take with her to campus as she refuses to eat in the cafeteria. The patient has no family history of heart disease or diabetes, however both her parents are on medication for high blood pressure. Her paternal grandmother died of breast cancer at age 47. Her maternal grandmother suffers from severe osteoporosis and her mother is taking prescription medications to slow bone loss. Trisha was hospitalized briefly in her junior year of high school for exhaustion and dehydration. Hospital records note that she reported skipping meals to fit into a dress for a dance. Recent lab work shows that Trisha is moderately anemic. Her cholesterol levels are normal. Her average resting heart rate is 64 and her average resting blood pressure is 88/60. Trisha feels sluggish and wants an assessment of her current health. She struggled with her weight in high school and reports that while she does not want to slip back into bad habits, she does want to maintain a slim figure. Height: _______5’ 10”________ Weight: _______122lbs___________ BMI:  Calculate Trisha’s BMI based on her height and weight and describe the implications of this number. Trisha’s BMI is 17.5, which is much lower than needed. This is borderline unhealthy.

Activity Level: BMR and TDEE (Output): Trisha reports running 3-5 miles every morning at a moderate pace. Occasionally, she adds in a night workout, either lifting light weights or taking an aerobics class. She always walks to class and she always takes the stairs. © 2014 Project Lead The Way, Inc.



Compute Trisha’s BMR.

Trisha’s BMR is 1425.4 

Discuss the activity factor used in the Harris-Benedict Equation and calculate TDEE.

The activity factor reasons how many calories Trisha uses per day. Trisha uses 2458.815 calories a day.

Food Intake (Input): Trisha completed a food diary for one week. Analysis of her food choices revealed the following results: Average calories consumed per day Average fat consumed per day Average saturated fat consumed per day Average carbohydrates consumed per day Average protein consumed per day Average sodium consumed per day

1601 42g 25g 65g 55g 1480mg

Trisha reports eating 5 servings of vegetables per day. She does not eat fruit as she avoids the sugar. Trisha eats no rice, pasta, or bread products. Occasionally she has a piece of whole grain toast before she goes running. She eats beans, egg whites, tofu, and fish for protein. She reports drinking 8-10 glasses of water a day. She does not drink soda or coffee, but she does drink 1-2 sugar-free energy drinks per day. She sometimes skips meals if she forgets to pack food to take to campus. Trisha does not eat fast food and only orders salad (with the dressing on the side) when she eats out. Calorie Deficit or Surplus (Compare Inputs and Outputs):  Compare calories consumed versus calories expended. Trisha uses 2458.815 calories; however, she only eats 1601 calories a day. This means she burns 857.815 calories a day. 

Describe what will happen to Trisha’s weight over the next month if she continues the same eating patterns. Show your work.

It takes 3500 calories to lose a pound, and 3500/857.815 is 4. Therefore, Trisha would lose a pound every four days, resulting in losing 7.5 pounds a month. Overall Assessment:  Discuss overall implications of BMI and any energy imbalance on overall health. © 2014 Project Lead The Way, Inc. Human Body Systems Activity 3.2.5 Student Resource Sheet: Trisha Knowles – Page 2

Energy imbalance leads to a lack in energy. Trisha often feels sluggish because she doesn’t have the energy needed for all of her daily activities. Her BMI shows that she doesn’t have the body fat necessary for her daily life. 

Analyze food choices o Is the client getting enough of each of the designated food groups? Trisha isn’t getting enough fats, sugars, or carbs, which could give her more energy to be able to do the things she wants. She also should invest in more calcium due to her family’s history. o How does consumption of fats, carbohydrates, proteins and sodium compare to recommended values?

Trisha isn’t taking in enough of these food groups. She is taking in 42 g of fat, when it’s recommended that she taken in 44-78. She is also taking in 65g of carbs, when she should be taking in 225-325g. Her protein levels are normal, but her sodium levels are low.



Propose ways to bring the energy input and output in line with Trisha’s health goals. Describe final recommendations to improve Trisha’s overall health and help her regain energy and strength. How should Trisha alter her eating habits and her activity? Link your recommendations to her personal health history and her family history.

Trisha shouldn’t worry so much about her weight. While she is eating healthy foods, she isn’t eating enough of them which results in her feeling sluggish and may cause more problems in the future. She is moderately anemic, which requires her to eat more often than she is. She should eat the amount of calories necessary to complete all of her daily activities, or at least the recommended levels, or else she may end up in the hospital for exhaustion and dehydration once more. She should intake more sodium, but not a lot, since her parents are on medication for high blood pressure. Her activity is slightly high, but fine as long as she is eating the calories to accommodate for it. Finally, she should eat more dairy, for the intake of calcium, due to her family’s history of weak bones.
