Table 2 Formulas for calculating energy requirements, macronutrient allowances and adequacy of intake of macronutrients in Filipino elders.

From: Physical activity, energy requirements, and adequacy of dietary intakes of older persons in a rural Filipino community

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
