_Calories Needed per Day for Normal Individuals_

[Sidenote: _Business of Growing_]

This depends upon age, weight, and physical activities; the baby and the
growing child needing many more calories per pound per day than the
adult, who has to supply only his energy and repair needs. The aged
require still less than the young adult. As to weight; I have told you
why overweight individuals need so little. As to physical activities;
the more active, obviously the more calories needed, for every movement
consumes calories.

exercise is not taken while doing the mental work) the work is not so
well done.

_Example of Finding Number of Calories Needed_

1. Determine normal weight by rule.

2. Multiply normal weight by number of calories needed per pound per
day.

For example, say you weigh 220 or 125 lbs., but b
