Question

Krause's Food & the Nutrition Care Process 14th edition Chapter 23 Case Study

Guillermo is a 32-year-old former college athlete who has been competing in long-distance triathlon and marathon events for the past year. He complains of low energy as training and racing duration increases and is plagued by gut issues—gas and bloating after meals, nausea, and vomiting during races. He also suffers from sleep issues, waking up frequently during the night. He works full time at a stressful job as manager of an electrical contracting firm and trains in swimming, cycling, and running 10 to 12 hours/week.

Assessment

His height is 5ft 9 in and his weight is 174 lb. His body composition analy- sis as measured by the RD using the ISAK method was 6.8% (10.4 lb body fat, 164 lb [74kg] FFM). He is satisfied with his body fat percentage but would like to reduce his weight if possible to lighten up for the running portion of his events.

Urine specific gravity was assessed to determine hydration status on three visits: 1.035, 1.025, and 1.030
Cholesterol levels were 250, HDL 50, LDL 170, triglycerides 160; all other values were within normal limits.

Using the Cunningham method to calculate REE:
500 (22 x FFM [Kg]) 500 (22 74) 2128 REE

Day off training: Activity factor 1.2, approx. 2553 calories
1-2 hours steady state training: Activity factor 1.4 approx. 2979 calories

3-4 hours steady state training: Using Activity factor 1.6 approx.3404 calories

4-6 hours training steady state: Using 1.73 Activity factor approximately 4581 calories

3041 calories, 216 g protein (2.77 g/Kg) (28%), 249 g carbohydrates (3.15 g/kg)(33%), 13.5% saturated fat, 1172 mg cholesterol, 5634 mg Na RDA: 64% potassium, 85% Ca and folate, 26% C, 30% E, 13% K, dietary fluid intake 9 cups

Assessment

Gut/Energy Antagonists:

Whole food portion of diet appears to be:

Low in calories: 3041 calories (4141 with sport fuel) vs. 4581 calories required

Carbohydrates: 249 g carbohydrates (3.15 g/kg) (33%) (497 g sport fuel), vs. a minimum of 5 to 7 g/kg 395-553 g

High in fat (38% total cal), saturated fat and cholesterol 1172 mg and so- dium 5634 mg

Low in antioxidants

Excessive in fat pre-workout breakfast

Excessive in sport fuel carbohydrates and sodium for 2-hour bike portion of ride

Excessive in mealtime calories and protein

Questionable whether athlete can tolerate FODMAPs foods, i.e., onions, beans, mushrooms, cream cheese, dairy (lactose), sport fuel sources of HFCS, and gluten

Intervention

Increase meal frequency and calories while modifying fat, sat fat, and cholesterol

Increase plant-based tolerable sources of protein and complex carbohy- drates

Modify amounts of animal protein at mealtime to 4 to 5 oz (30 to 35 g Improve leafy green vegetable intake via juicing if whole food veggies not desired or tolerate

Improve intake of antioxidant rich fruits and fruit juices without added sugar

Recommendations

Probiotic, EAA to heal and strengthen gut; enzymes before meals
Adjust sport fuel intake, decrease electrolyte pills, reduce and modify carbohydrate-containing liquids and source, switch to waxy maize if maltodextrin or HFCS contributing to issue

Meditation or yoga on day off from training and/or prayer or meditation 5 to 10 minutes a day for relaxation

Melatonin and/or theanine for sleep issues, restlessness

Further Biochemical Evaluation and Testing

Hydrogen/methane breath testing, gut dysbiosis

Spectracell to determine extent of vitamin or mineral deficiency, assimilation, and absorption

Upper/lower GI series if elimination diet, FODMAPs diet, and adjustments in eating/sport fuel do not resolve problems during training and racing

Follow-up lipid profile after 9 to 12 weeks on modified fat, saturated fat, and cholesterol diet

Explanation / Answer

1) The calorie requirement of a person depends on his/her total daily energy expenditure (TDEE). TDEE can be calculated by estimating basal metabolic rate (BMR).

Cunningham formula for calculation of BMR is, BMR = 500 + (22 x lean body mass)

Lean body mass is total weight minus fat weight in kg.

Guillermo has a lean body mass of 74 kg

So, BMR = 500 + (22 x 74)

= 500 + 1628

= 2128

Total daily energy expenditure (TDEE) is calculated by multiplying BMR with a factor based on the activity level

Here, Guillermo is undergoing sports training in addition to his routine work. He is highly active. The multiplying factor for highly active individual is 1.9

TDEE = BMR x 1.9

= 2128 x 1.9

= 4043

Guillermo has to take 4043 calories per day.

Macronutrients are proteins, fats and carbohydrates

Fat intake: Around 20 -35% of energy requirements. Since, Guillermo is thinking of reducing his weight, we can place him under lower limit of fat intake level, 20% of TDEE requirement to come from fat

808.6 calories to come from fat (20% of 4043)

= 808.6 / 9 g of fat to be consumed per day

= 89.84 g of fat per day

Protein intake: It should be around 250 grams if we are taking lot of calories. 250 grams of proteins will provide 1000 Kcal.

Carbohydrate intake: The rest of TDEE should come from carbohydrates.

= 4043 - (808.6 + 1000)

= 4043 - 1808.6

= 2234.4

2234.4 calories to come from carbohydrates.

= 2234.4 / 4 grams of carbohydrates to be consumed per day

= 558.6 grams of carbohydrates to be consumed per day
