Problem 174 : To find my daily Calorie requirement. 

 Method. — Use the following tables carefully. 



TABLE 1 

 Daily Calorie Needs 



For a child under 2 years 900 Calories 



For a child from 2 to 5 years 1200 Calories 



For a child from 6 to 9 years 1500 Calories 



For a child from 10 to 12 years 1800 Calories 



For girl from 13 to 14 years (woman, light work, also) . 2100 Calories 

 For boy from 12 to 14, girl from 15 to 16 (man, seden- 

 tary) 2400 Calories 



For boy from 15 to 16 years (man, light muscular work) 2700 Calories 

 For man (moderately active muscular work) .... 3000 Calories 



For farmer (busy season). 3200 to 4000 Calories 



For ditchers, excavators, etc 4000 to 5000 Calories 



For lumbermen, etc 5000 and more Calories 



NOTE. — According to Professor Chittenden, a person doing moderate work 

 should not eat more than ^j of an ounce of protein for each pound of his body weight 

 and enough fuel foods added to bring the total up to between 2500 and 3000 Calories. 

 This is a good general rule to follow. Still another check on your daily needs when 

 doing light work may be obtained by multiplying your body weight by 16.1 Calories. 

 The result will be approximately your daily Calorie requirement. 



But the body needs more energy when it works hard. The 

 hourly Calorie requirement is shown in the following table. 



TABLE 2 



Hourly Outgo in Heat and Energy from the Human Body as Deter- 

 mined in the Respiration Calorimeter by the United States 

 Department of Agriculture 

 Average (154 lb.) Calories 



Resting (asleep) 65 



Sitting up (awake) 100 



Light exercise 170 



Moderate exercise 290 



Severe exercise 450 



Very severe exercise 600 



Observations. — Make very careful observations in tabular 

 form giving the exact Calorie requirement of your own body, us- 

 ing first the age requirement (see Table 1), second the sex require- 

 ment (Table 1), third the occupation requirement by the hourly 

 standard (see Table 2). Use judgment in estimating light exer-
