CALORIE REQUIREMENT 343 



Suppose that a man weighing 150 pounds spent his 24-hour 

 day by sleeping 8 hours, sitting 8 hours, typing 2 hours, standing 

 4 hours, walking 2 hours, he would require 2570 Calories a day. 



150 X i X 8 = 600 sleeping 150 X f X 4 = 450 standing 



150 X |X8 = 800 sitting 150 X 1J X 2 = 450 walking 



150 X ^ X 2 = 270 typing 



From these two tables one can easily compute his own energy 

 requirement.

PROBLEM V. WHAT IS THE DAILY CALORIE REQUIREMENT? 



Workbook Exercise. Check up your day's total Calories by com- 

 paring it with your requirement by body weight and by the tables 

 given on page 342. 



Head your paper : Name , age , weight lbs. 



Daily Calorie needs 



Amount used 



Discrepancy 



How does your day's total Calories compare with that given in the 

 table of daily needs of a person of your age, doing the kind of work 

 you did for the day? How can you account for any discrepancy? 



Can you suggest any improvement in your diet? Check on the 

 vitamin content of your diet. 



Malnutrition. When the body cells do not receive a proper 

 amount of food or the right kinds of food, then a loss in body weight 

 may occur, and we say that person is undernourished, or is suffer- 

 ing from malnutrition. An undernourished person is likely to be 

 susceptible to disease, to tire easily, and to be sensitive to cold and 

 exposure. Frequently, girls having large bones in their skeleton 

 attempt to get thinner, and find all too soon that they have only 

 made themselves ill without much reducing their body weight, 

 which is largely due to these heavy bones. Never take up a " fad " 

 diet without first consulting your own or the school physician.
