Physical Readiness - Get there!
We lose 1 month of life expectancy for each pound our weight is above average. So if you are 15-pounds overweight, the LLE is thus 15 months, or 1.25 years less. Stop being selfish: Lead.

What Is Body Fat?
Having an excess of body fat leads to the condition of obesity, and that can be unhealthy. Some people are more genetically predisposed to excess body fat, and others build it up from lack of exercise and bad diets.
But body fat stored in the abdominal region can be reduced by diet and exercise. Women and men store body fat differently – after the age of 40, or after menopause in the case of women, reduced sexual hormones can lead to excess body fat around the stomach in men, and around the buttocks and thighs in women.
Body Fat and Being Overweight
Being overweight does not necessarily mean that you have an excess of body fat. Powerfully muscled people often are overweight. A certain amount of body fat is also necessary to staying alive. Human beings also have a specialized kind of body fat called "Brown fat." It is located mainly around the neck and large blood vessels of the thorax, and it serves to generate heat to help keep us warm in severe cold.

While in overweight status, sailors are ineligible for promotion, ineligible for many volunteer assignments and schools, will adversely effect their Navy FITREP and are not eligible to
What's Wrong with Excess Body Fat?
As we've said, it's appropriate to think of fat as an important producer of essential hormones. Our bodies' functions are controlled by hormones, and so excess or lack of critical ones can seriously affect our health. Scientists have learned that excess body fat, especially abdominal fat, disrupts the normal balance and functioning of these hormones.
It is known that body fat pumps out immune system chemicals called cytokines that can increase the risk of cardiovascular disease. These biochemicals are thought to make cells less sensitive to insulin, blood pressure, and blood clotting.
Another reason that abdominal body fat in excess can be so harmful is that it is located near the portal vein, which carries blood from the intestinal area to the liver. Substances released by body fat, including free fatty acids, enter the portal vein and travel to the liver, where they can impede its functioning.
Abdominal body fat is directly linked with higher total cholesterol and specifically with the so-called "bad" cholesterol that can clog arteries and lead to a heart attack.
Insulin resistance means that your body's muscle and liver cells don't respond adequately to normal levels of insulin. Insulin is responsible for carrying glucose into the body's cells. When there is insulin resistance, glucose levels in the blood rise, heightening the risk for diabetes.
