Nutrition
Human Nutrition, study of how food affects the health and survival
of the human body. Human beings require food to grow, reproduce,
and maintain good health. Without food, our bodies could not stay warm,
build or repair tissue, or maintain a heartbeat. Eating the right foods
can help us avoid certain diseases or recover faster when illness occurs.
These and other important functions are fueled by chemical substances in
our food called nutrients. Nutrients are classified as carbohydrates,
proteins, fats, vitamins, minerals, and water.
Nutrients are classified as essential or nonessential. Nonessential
nutrients are manufactured in the body and do not need to be obtained from food. Examples
include cholesterol, a fatlike substance present in all animal cells. Essential nutrients
must be obtained from food sources, because the body either does not produce them or produces
them in amounts too small to maintain growth and health. Essential nutrients include water,
carbohydrates, proteins, fats, vitamins, and minerals.

Five food groups: meats and other protein-rich foods
(2 to 3 servings a day plus one cup of milk); cereals and other starchy
foods (9 servings a day); vegetables and fruits (5 servings a day); fatty
foods (9 servings a day- one tablespoon each); sugars (10 servings a day-
one tablespoon each).

Weight Cycling
Weight cycling is the repeated loss and regain of body weight.
When weight cycling is the result of dieting, it is called
"yo-yo" dieting. A weight cycle can range from small weight
losses and gains (5-10 lbs. per cycle) to large changes in weight (50 lbs. or more per cycle).
Some experts believe that weight cycling may be harmful to your
health and that staying at one weight is better than weight cycling,
even for those people who are obese. However, there is no convincing
evidence to support these claims, and most obesity researchers believe
that obese individuals should continue trying to control their body
weight despite some weight cycling.
So far studies have not definitively shown that weight cycling is harmful.
However, further research on the effects of weight cycling is needed.
In the meantime, a fear of weight cycling should not stop an obese person from achieving
a modest weight loss. Although health problems associated with weight cycling have not been
proven, the health-related problems of obesity are well known.
Weight cycling does not appear to increase the amount of fat tissue in people who lose
and regain weight. Researchers have found that after a weight cycle, people have
the same amount of fat and lean tissue as they did prior to weight cycling.
