All the energy needed for growth and repair of the body, for muscular activity of
all kinds and for all the work done by cells comes from the metabolism of
carbohydrate, fat, protein and alcohol. The numerous other items of the diet, even
though essential for other reasons, do not provide energy, although many are directly
involved in the chemical reactions which yield energy. If the diet is adequate and
properly balanced the energy normally comes chiefly from carbohydrate and fat,
while most of the protein is used for cell growth and repair. When there is not
enough carbohydrate and fat, the protein is used for energy and is then not available
for other purposes. As dietary protein is generally less abundant than carbohydrate
and fat, and usually more expensive, using protein for energy is comparatively
wasteful. In some communities, however, there may be plentiful protein and it
may then be eaten in sufficient quantity to be used for both cell building and for
energy.
The intake of food is governed in health by the appetite which under ordinary
conditions controls the weight of the body with remarkable precision. Many people
taking only moderate care are able to keep their weight more or less unchanged
over several decades. If they take food in excess by only a small amount, that
excess energy can be disposed of as heat and thereby prevent fat accumulation.
This seems to work very efficiently in some people. It is, however, easy to override the natural controlling mechanism and consume substantially more energy
than is required. When this happens the excess energy is stored in the body as fat.
During ageing there is a fall in the weight of the bones, due to loss of minerals,
plus a fall in the weight of the muscles, hence if the total body weight remains
constant there must be compensatory changes, mainly an increase in the body fat.
