What is the AMDR range for protein?

• A. 15-25%
• B. 10-35%
• C. 40-60%
• D. 0-15%

Answer: (B)

The main idea here is understanding what portion of daily calories should come from protein to support health. The official AMDR for protein is 10-35% of total daily calories. This range is broad enough to accommodate different needs from sedentary adults to active individuals, while ensuring enough protein without crowding out other macronutrients like fats and carbohydrates. For a 2000 kcal day, that translates to about 50–175 grams of protein.

Why this range fits best: it sets a lower limit that helps prevent inadequate protein intake, and an upper limit that avoids excessively high protein at the expense of other nutrients. The other options fall outside or don’t capture the official range: 0-15% would likely under-consume protein, 40-60% would overly skew the diet toward protein and away from fats and carbohydrates, and 15-25% is narrower than the established AMDR, not representing the full recommended span.
