Benedict has lately produced evidence to show that the basal metabolism,

or heat production, at rest is not governed entirely by such factors as
body weight and body surface, but by the amount and activity of the
active protoplasmic cells of the body--the cells that compose the organs
and muscles and blood
Benedict has lately produced evidence to show that the basal metabolism,
or heat production, at rest is not governed entirely by such factors as
body weight and body surface, but by the amount and activity of the
active protoplasmic cells of the body--the cells that compose the organs
and muscles and blood. The condition of these cells when the
measurements are taken (which may be influenced by age, sleep, previous
muscular exercise and diet) materially affects the amount of heat
production and the requirements in energy food. Such experiments show
why a man must literally burn up his own body, if he takes in no fuel in
the form of food. Benedict"s views also account for the higher energy
requirement of men as compared to women, who, as a rule, have more fat
and less muscular tissue than men.
