Calculation of Dietary Description
CALORIE ALLOWANCE
- based on desirable weight
- absence of weight & height table- Thanhaussers method
Formula:
Height in cm 100= weight in kilogramFor Filipinos: less 10%

SAMPLE COMPUTATION
25 year-old male , professionalbasketball player, Filipino
Height = 511He plays basketball every day , 2x a dayFor today, he had the following for
breakfast:2 boiled eggs, 4 slices of white bread, 1cup of fresh milk, 2 slices of mangoes, 2
small bananas (lacatan)
7/29/2019 Calorie Contents
7/27
Height = 511Computation:
511 = 71 inches x 2.54= 180.34 cm 100= 80.34 kg [80.34 (10%)]
= 80.34 8.034= 72.306 or 72 kg

Calorie Allowance
STEP 1Calculate the basal calorie used for 24H based
on DBW
Formula:BMR (basal metabolic rate)= 1 cal/kg DBW/hour
* BMR energy expenditure by the body when
at rest, but not asleep, under controlledconditions of thermal neutrality, about 12hours after the last meal and depends onweight, age, and gender

Computing for CalorieAllowance
BMR = 1 cal/DBW/hr
= 1 cal x 72 x 24
= 1,728 calories

Calorie Allowance
Step 2 Energy needs for Physical Activity(PA)
1. Bed rest (sick) 10% of BMR2. Sedentary 30%
- couch potatoes, little exercise
3. Light work 50%- sports 1-3 days/week

4. Moderately active 75%
- sports 3-5 days/week
5. Very active 100%- sports 6-7 days/week
6. Extra hard
- extremely hard dailyexercises/sports/physical job

STEP II
Physical activity is very active = 100%
1728 X 100% (1) = 1728 calories

Step 3 Specific Dynamic Action of Food
(SDA)
Formula:(BMR + PA) 10%

STEP III Specific Dynamic Action of Food(SDA)
10% (BMR + PDA)
= 10% (1728 + 1728)= 0.1 (3456)
= 345.6 calories = 346 calories

Step 4 Summary of Total EnergyRequirement (TER)
Formula:
BMR + PA + SDA
* Round off the sum to the nearesthundred

Total Energy Requirement (TER)
BMR + PA + SDA
= 1,728 + 1,728 + 346
= 3,806 calories = 3,800 caloriesround off TER to the nearest hundred
