• BMI

  Interpretation<|>Underweight<|>HEALTHY<|>Overweight<|>Obese I<|>Obese II<|>Extremely Obese
• Desirable Body Weight (DBW) for Infants

  1. 0 - 6 mos.: DBW = Birthweight (kg) + (age in mos. X 600)

  2. 7 - 12 mos.: DBW = Birthweight (kg) + (age in mos. X 500)

  3. If birthweight unknown, use 3000 grams
• Desirable Body Weight (DBW) for Children

  DBW = age in years x 2 + 8
• Desirable Body Weight (DBW) for Adults (Tanhausser's Method)

  DBW = ht. in cm - 100 - (10%)
• BMR Calculation

  Rule of thumb - 1 kcal per kg per hour (Male)<|>Rule of thumb - 0.9 kcal per kg per hour (Female)<|>Example: Male 75 kg = 1 kcal X 75 X 24 = 1,800 kcal<|>Example: Female 65 kg = 0.9 kcal X 65 X 24 = 1,404 kcal
• Total Calorie Requirement/day for Infants

  1. 0 - 6 mos.: TER = DBW x 120 cals/day

  2. 7 - 12 mos.: TER = DBW x 110 cals/day
• Total Calorie Requirement/day for Children

  TER = 1000 + (100 x no. Of years)
• Total Calorie Requirement/day for Adolescent

  TER = DBW x 45 cals/KDBW
• Total Calorie Requirement/day for Adults (Krause Method)

  TER = DBW x PA value
