- The Acceptable Macronutrient Distribution Ranges (AMDRs) reflect the ranges of intakes for each class of energy-yielding nutrient associated with reduced risk for chronic disease while providing adequate intakes of essential micronutrients. Your patient is on an 1800 calorie diet. Calculate the AMDR range in calories first, then determine how many grams of carbohydrates, protein, and fat this would be.
