to do hard physical labor to eat, had to walk briskly up and down
steep terrain to get anywhere. But today, few North Americans output
very much physical energy in process of daily life or work. Not only
cars, but all of our modern conveniences make it possible to live
without ever breaking into a sweat. We pay for this ease; it costs
us a significant degree of health.
Exercise has many benefits when combined with excellent nutrition.
It creates an overall feeling of well-being that can not be created
by diet alone. Exercising temporarily makes the heart beat faster,
increasing blood circulation throughout the body right out to the
tips of your fingers and toes. This short-term elevated flow of
blood flow brings increased supplies of oxygen and nutrients to all
parts of the body, facilitating healing and repair. Without revving
up your engine every day many of the body's systems never get the
sludge burned out of them and never perform optimally.
Exercise also changes the metabolic rate so your body burns more
calories--not only while you are exercising, but also for a 24 hour
period following exercise. This maintains a healthful body weight
into old age, or helps to lose weight. Most people find that
exercise in moderation does not increase appetite, so that it is
possible to consistently burn more calories in a day, and gradually
reduce weight if that is desirable.
