Harris Benedict Formula - Revised 1984
STEP 1: Basal Metabolic Rate (BMR)

Male:
88.362 + (13.397 x user weight in kg) + (4.799 x user height in cm) - (5.677 x user age) = Basal Metabolic Rate (BMR)

Female:
447.593 + (9.247 x user weight in kg) + (3.098 x user height in cm) - (4.330 x user age) = Basal Metabolic Rate (BMR)

Gender:


Weight:
kg   OR   lbs

Height:
cm  OR   ft  inches

Age:

BMR
STEP 2: Daily Energy (Calorie) Requirements (DER)

Daily Energy (calorie) Requirements (DER):
BMR x Activity Factor = DER

STEP 3: Acceptable Macronutrient Distribution Ranges Calculations (AMDR)

Grams of Carbs per day:
DER x Acceptable Macronutrient Distribution Range % (AMDR) ÷ 4 calories/gram = _____ Grams of Carbs per day

Grams of Protein per day:
DER x Acceptable Macronutrient Distribution Range % (AMDR) ÷ 4 calories/gram = _____ Grams of Protein per day

Grams of Fat per day:
DER x Acceptable Macronutrient Distribution Range % (AMDR) ÷ 9 calories/gram = _____ Grams of Fat per day

AMDR Average:
For an average healthy adult the percent values are:
55% carbs
15% protein
30% fat

Press the switch below to disable/enable preset limitations
The restricted AMDR limits are:
45-65% carbs
10-35% protein
20-35% fat
