Dr. Felix Oswald says that “during the zenith period of
Grecian and Roman civilization monogamy was not as firmly
established as the rule that a health-loving man
should content himself with one meal a day, and never eat till he
had leisure to digest, i.e., not till the day’s work was
wholly done.
Among the many things that have been offered as an
explanation for their physical, mental and moral decline
has been their sensuous indulgence in food which came with
power and riches.
The ancient Greeks–the finest of people, physically and
mentally, that ever lived–ate but two meals a day. The
same was true of the ancient Hebrews and it is the custom of some
of the best fighting races in India today.” The adoption of
three meals a day, in England, came along with the increasing
prosperity of that country.
