From the charts of the average heights and weights of men varying
between fifteen and fifty-five years old, given by American life
insurance companies, Mr. H. V. Atkinson, of my laboratory, has
calculated the basal metabolism in a table here presented.
Unfortunately, the weights given in these statistics include clothes
worn by the individuals. The calculated heat production, however, is in
each case based upon the weight without clothes. The table is computed
from the following values:

Calories per
square meter
Age in years of surface

15 44
20-50 40
55 37

The table may also be used as follows:

To find the metabolism of--

Women between twenty to fifty years, multiply values for man
by 0.93.

Boys of twelve to thirteen years, multiply values for boys of
fifteen years by 1.10.

THE BASAL METABOLISM OF MEN

_Calculated from values of the basal metabolism determined by the
methods of DuBois and applied to a table showing the average weights of
221,819 men of different ages and heights compiled from the statistics
of the medico-actuarial investigation of 1912._
