The formulas to calculate the acceptable macronutrient distribution ranges (AMDR) are:
Carbohydrates (C):
\[ C = 45\%-65\% \times \frac{Dkcal}{4} \]
Protein (P):
\[ P = 10\%-35\% \times \frac{Dkcal}{4} \]
Fat (F):
\[ F = 20\%-35\% \times \frac{Dkcal}{9} \]
Where:
AMDR, short for Acceptable Daily Macronutrient Range, is a term used in science to describe the healthy amounts of carbs, proteins, and fats a person should eat each day. These ranges are based on a percentage of calories. Carbs and protein both provide 4 calories per gram and fat provides 9 calories per gram.
Let's assume the following values:
Using the formulas to calculate the Macronutrient Intake:
Carbohydrates (C):
\[
C = 45\% \times \frac{2000}{4} = 225 \text{ grams} \quad to \quad C = 65\% \times \frac{2000}{4} = 325 \text{ grams}
\]
Protein (P):
\[
P = 10\% \times \frac{2000}{4} = 50 \text{ grams} \quad to \quad P = 35\% \times \frac{2000}{4} = 175 \text{ grams}
\]
Fat (F):
\[
F = 20\% \times \frac{2000}{9} = 44.44 \text{ grams} \quad to \quad F = 35\% \times \frac{2000}{9} = 77.78 \text{ grams}
\]
Therefore, for a person burning 2000 calories a day:
