What are the typical AMDR ranges for carbohydrates, protein, and fat?

• A. Carbohydrates 20–40%, protein 40–60%, fat 15–25%
• B. Carbohydrates 30–60%, protein 10–40%, fat 25–45%
• C. Carbohydrates 45–65%, protein 10–35%, fat 20–35%
• D. Carbohydrates 50–70%, protein 5–15%, fat 15–25%

Answer: (C)

The everyday balance of energy from each macronutrient is what AMDR aims for. The standard ranges assign 45–65% of daily calories to carbohydrates, 10–35% to protein, and 20–35% to fat. This combination ensures enough energy and nutrients from each group: carbohydrates provide quick energy, protein provides amino acids for tissue maintenance and enzymes, and fat supplies essential fatty acids and fat-soluble vitamins without overshooting total energy. The other options stray from these ranges by pushing one macronutrient outside the accepted limits—too much protein or too much fat, or carbohydrates set too low or too high—so they’re not consistent with the recommended balance.
