Learn About the Science of Burning Fat

fat-cell-comicFitness professionals must learn the science behind what they are doing and teaching. That is why I like to share articles I find that will help your understanding of physiology. Please read this article by Dr. Len Kravitz posted in Ideadfit. It’s called the Science of Fat Burning. While it is quite short, and to read more about the physiology of burning fat, it gives you a good understanding of  how fat is stored and mobilized and what happens when it reaches the muscle where it will be used as fuel for muscular contraction.

Below is an excerpt. Click on the above link to read the full article. TIP: Read the highlighted words (Fat, calorie, athletic performance) for even more great information.

Fat may seem like the enemy of civilized people—especially sedentary ones. Yet we cannot live without it. Fat plays a key role in the structure and flexibility of cell membranes, and it helps regulate the movement of substances through those membranes. Special types of fat, known as eicosanoids, send hormone-like signals that exert intricate control over many bodily systems, mostly those affecting inflammation or immune function.

Of course, the best-known function of fat is as an energy reserve. Fat has more than twice the energy-storage capacity of carbohydrate (9 calories per gram vs. 4 calories per gram). It has been estimated that lean adult men store about 131,000 calories in fat (Horowitz & Klein 2000), enough energy to keep the average person alive for about 65 days.

For fitness professionals, the prime concern arises when the body’s fat-storage function works too well, hoarding unwanted fat that makes people unhealthy and self-conscious about their appearance. Understanding how fat travels through the body can help personal trainers work with clients to reduce excess body fat and improve athletic performance.
