151119 Fat-necessary or not?

A key component in assessing an individual’s health and physical fitness is knowing the body composition makeup. Obesity (excessive body fat relative to body mass index (BMI) of 30 kg/m2 or more) and becoming overweight (Adults with BMI between 25-29.9 kg/m2 or with children being in and over the 95th percentile for their age and sex) is at epidemic proportions in the United States and the trend is gathering momentum.

Right now, we are at the top of the fat list compared to the majority of the nations in the world-an unfortunate but sad fact.

Being obese brings serious health consequences and reduces life expectancy by increasing the risk of developing serious diseases such as coronary heart disease, hypertension, aka the silent killer, type 2 diabetes, obstructive pulmonary disease, osteoarthritis and even certain kinds of cancer.

Just as too much fat in the body can cause problems, so can too little. Our body needs fat to operate in a normal physiological fashion. For example the essential lipids such as the phospholipids are vital to cell membrane formation. The non essential lipids such as triglycerides which are found in the adipose (fat) tissue protect the body by providing a layer of thermal insulation. Fat tissue assists in storing metabolic fuel in the form of free fatty acids.

These same lipids are also involved in the storage and transport of the fat soluble A, D, E, and K vitamins and in helping to maintain the functionality of the nervous system. The menstrual cycle in females and the reproductive systems in both male and female rely on these cells, as does the growth and maturation processes of the pubescence child. 

Thus too little body fat as seen in those with eating disorders such as anorexia nervosa, or someone with an exercise addiction or even certain diseases such as cystic fibrosis can lead to serious physiological health related consequences.

The best option is to be in the normal range for body fat, not over or under the recommendations if you desire to have good health.
