The upper chart is for boys, the lower one for girls. The relative amount of Calories needed 

 for different ages are for (B), space between base line and first graph, basal metabolism 

 (G) growth, (A) activity, and (E) excretion, spaces between graphs (after Holt). 



(a) into your basal metabolic needs, (b) into growth of your body, 

 (c) into your daily activity (This, of course, will vary, depending on 

 the kind of work you do out of school), (a) the amount that goes 

 into excretion or body wastes. Remember that your growth calories 

 must come from protein food and that activity should come largely 

 from carbohydrates and fats. Compare carefully to see how near 

 your proportions are to the ideal condition. 



Do you eat the correct proportions of nutrients to give your dietetic 

 needs as shown by the charts given above ?
