Practice questions macronutrient calculations...

Description

You are conducting a dietary assessment on a 42 yo female, and are interested in the amount of calories and macronutrient sources of calories in her diet. Her anthropometric measures are: weight: 64kg, height: 1.67m, BMI 22.9. A diet analysis report of her 24 hr food recall indicates that the client has consumed: • • • •

170 g Carbohydrate 78 g Fats (lipids) 83g Protein 0 g Alcohol

1. Calculate her calorie consumption

2. What is the percentage of energy distribution from carbohydrates, fat and protein from her intake?

3. Is she meeting the DRI recommendations for macronutrients? (both absolute amounts and AMDR)

• • • •

170 g Carbohydrate 78 g Fats (lipids) 83g Protein 0 g Alcohol

1. Calculate her calorie consumption. 170g Carbohydrates x 4kcal/g =

680 kcal

78g fat x 9kcal/g=

702 kcal

83g protein x 4kcal/g=

332 kcal

0g alcohol x 7kcal/g= Total:

0 kcal 1714 kcal

2. What is the percentage of energy distribution from carbohydrates, fat and protein from her intake? (you can round to the nearest full number) Carbohydrates: 680kcal/1714kcal x 100% = 39.7% = 40% Fat: 702kcal/ 1714kcal x 100% = 41% Protein: 332kcal/1714kcal x 100% = 19.4% = 19% ---------------------------------------------------------------------------------------------100% Note: Always be sure to check that your % for each macronutrient adds to 100%. It is a quick way to double check that you have not made an error in calculating the number of calories from each macronutrient in the step above (question 1).

3. Is she meeting the DRI recommendations for macronutrients? (both absolute amounts and AMDR). Carbohydrate intake = 170 g (40% total energy) Carbohydrate AMDR = 45-65% - not meeting Carbohydrate RDA = 130 g – meeting Fat intake = 78 g (41% total energy) Fat AMDR = 20-35% - not meeting Fat RDA = Not determinable – N/A Protein intake = 83 g (19% total energy) Protein AMDR = 10-35% - meeting Protein RDA (absolute grams= 46g/d) = meeting Protein RDA based on body weight (0.8 g/kg) – 64kg x 0.8g/kg = 51.2g = meeting....
