James W. is a 65-year-old male hospitalized with dehydration secondary to a severe case of covid. He is 72 inches tall and weighs 196 pounds, down 25 pounds from his usual of one month ago. Currently his temperature is normal.

1. Calculate James’s BMI and determine his health risk status based on his weight classification. 26.6 kg/m^2

BMI = (weight in pounds x 703) / (height in inches x height in inches).

2. Assuming his usual body weight is 221 pounds, what percent weight change has he experienced? State his weight as a percentage of his usual weight. 12.75%

3. Categorize the patient’s risk of malnutrition based on weight change

4. Using an ideal body weight of 130 pounds, calculate his resting energy needs using the Mifflin–St. Jeor equation

Men: (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) + 5.

Women: (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) - 161.

Remember to convert pounds to kilograms by dividing by 2.2. Multiply the height in inches by 2.54 to convert to centimeters.

4. Use the acceptable macronutrient distribution range, calculate the grams of fat and carbohydrate that you would recommend.

5. Calculate James’s daily protein requirement based on 1.0 gram per kilogram of his ideal body weight.
