Muscle Versus Fat
All weight loss is not considered equal.
This is a mantra to live by as you embark on your weight management
program. Though we all are conditioned
to determine our success solely by the weight loss shown by the scale, it is much
more important to judge our achievements based on our changes in body
composition.
All weight loss is not GOOD Weight loss. All weight gain is not bade weight gain. -R. DeVito
Body Tissues
The human body consists of a variety of different types of tissues, lean
tissue and fat tissue. The lean tissues
include bone, muscle and organs. Muscle and
organs are considered metabolically active, whereas fat is metabolically much
less active. This means that muscle and
organs help to increase your metabolism and burn fat and calories, while fat
tissue does almost nothing. Therefore,
it is essential to maintain muscle tissue while losing fat, thus the additional
movement will increase your metabolism.
Muscle dose not weigh more than fat. It just takes up less space. |
Weight
It is important to realize that a pound of muscle is denser and more
compact than a pound of fat. It is
helpful to think of a pound of fat as a pound of feathers, and a pound of
muscle as a pound of iron. The pound of
feathers would clearly take up a lot more space than that same pound of
iron. By gaining lean body mass (water,
bone and muscle) while losing body fat, you will look and feel lighter, your
clothes will fit better and your overall sense of well being will improve. In summary, body weight is only one of the
many determining factors of success.
Changing your Body Composition
To decrease your percent of body fat, you need to create the right
balance between the calories you consume and the calories you expend. The most effective way to do this is to
decrease your consumption of calories and increase your activity level.
