Formulas for calculating energy requirements, macronutrient allowances and adequacy of intake of macronutrients in Filipino elders.

Reference

Formulas


Desired Body Weight (kg)1

DBW

(height in cm - 100) × 0.9

Basal Metabolic Requirement (kcal)

BMR

1 kcal/kg × DBW in kg × hours

Caloric allowance based on physical activity level

PAL

Sedentary or light activity

35 kcal/kg × DBW in kg × hours in light activities

Active or moderately active

40 kcal/kg × DBW in kg × hours in moderately active activities

Vigorous or vigorously active

45 kcal/kg × DBW in kg × hours in vigorous activities

Specific Dynamic Action of food (kcal)

SDA

10% of (BMR + PAL)

Total Energy Requirement (kcal/day)

TER

BMR + PAL + SDA

Change in Energy Requirements based on age

CER

≥ 60 to <70 y

10% decrease

≥ 70 y

20% decrease

Age-adjusted Total Energy

Requirement (kcal/day)

ATER

TER - (TER × CER)

Macronutrient Allowance

Allowance

Energy (kcal)

ATER in kcal

Protein (g)

(ATER in kcal × 0.60)/4 g per calorie

Fat (g)

(ATER in kcal × 0.25)/9 g per calorie

Carbohydrates (g)

(ATER in kcal × 0.15)/4 g per calorie

Adequacy of intake of macronutrients (%)

Adequacy

Energy

(Total caloric intake/ATER) × 100

Protein

(Protein intake/Protein allowance) × 100

Fat

(Fat intake/Fat allowance) × 100

Carbohydrates

(Carbohydrate intake/Carbohydrate allowance) × 100

Mean Physical Activity Level

MPAL

(Hours spent per activity × Energy cost of activity)/24 hours
