DIRECTIONS: Calculate the following using the subject below (Show the computation).
2, 34 years old male, 5’6” tall, obese performing light activity.
Answer :
Given 34 years old male, 5'6'' tall
A) Desirable body weight by Tannhauser’s Method :
Formula:
Desirable body weight = Height in centimeters -100
1 feet = 12 inches, 1 inche = 2.54 Cm
Height = 5 feet 6 inches ( 5'6'')
= 5 feet 12 incehs / feet + 6 inches
= 60 inches + 6 inches
= 66 inches 2.54 centimeters / inche
Height = 167.64 centimeters
Desirable body weight = Height in centimeters -100
= 167.64 cm - 100
Desirable body weight = 67.64 Kg
It should be deduct with additional 10% to adjust body frame.
Desirable body weight = 67.64 Kg - (10 % of 67.64)
= 67.64 Kg - 6.76
= 60.88 kg OR 61 Kg
Desirable body weight = 61 Kg .
B) Basal metabolic rate by simple method :
Formula:
Basal metabolic rate (BMR) = 88.4 + (13.4 weight in Kg ) + ( 4.8 height in Centimeters) - ( 5.68 age in years)
weight = 61 Kg
Height = 167.64 Cm
Age = 34 years
These values are apllied in the formula:
Basal metabolic rate (BMR) = 88.4 + (13.4 61 Kg ) + ( 4.8 167.64 Centimeters) - ( 5.68 34 years)
= 88.4 + ( 817.4 ) + ( 804.67 ) - ( 193.12 )
= 1710.4 - 193. 12
= 1517 .3 Calories
Basal metabolic rate (BMR) = 1517 .3 Calories.
C) Physical activity requirement :
The 34 yeal old man performs light activity. Th physical activity requirement shows that light activity and that physical activity level according to that is 1.375.
D) Specific dynamic action of food ( SDA):
Formula: SDA = 10 % ( BMR + PAL)
= 10% ( 1517.3 + 1.375 )
= 10% 1518.7
= 151.87 K cal
Specific dynamic action of food ( SDA) = 151.87 Kcal.
E) Total energy requirement :
It is calculated by using the formula as:
Total energy requirement = Basal metabolic rate (BMR) + Physical activity level (PAL) + Specific dynamic action of food ( SDA)
Total energy requirement = BMR + PAL + SDA
= 1517.3 + 1.375 + 151.87
= 1670.5
Total energy requirement = 1670.5 Kcal / day.
