How Your Body Burned Fat??

I come across this article at bodybuilding.com (my favorite site for bodybuilding info), and feel that I should share with everyone, since this is truly benefit to all human being. So, this is my very first article about bodybuidling.... on this blog.

How Your Body Burned Fat?

Body fat storage is controlled by many different factors ranging from diet to hormones to receptor density. Of importance to this article is receptor density. Without diving to deep into the nerdy science stuff, a receptor can be looked at like a lock that a key (i.e. a hormone) fits into.

Activation of the alpha1 and beta-receptors is lipolytic (causes fat breakdown) while activation of the alpha2 receptor is anti-lipolytic (blunts fat breakdown). Stubborn fat (eg: your stomach/abs) areas have a high density of alpha2 receptors, making it harder for fat breakdown to occur in that area.

In order to burn stubborn fat we must override the inhibitory effect of the alpha2 receptors. Now that we know the cause of stubborn fat areas we need to learn how to burn the fat!

Stored Triglycerides-Body Fat We Want To LOSE

While all cells contain some fat, it is mainly stored in muscle (intramuscular triglycerides) and in adipose tissue (body fat). Adipose tissue is the body's main fat storage site and the fat we all want to lose.

Adipose tissue is divided into individual cells called adipocytes. These adipocytes hold stored triglyceride (1 glycerol molecule bonded to 3 fatty acids) droplets, which serve as a source of energy for the body. These droplets make up 95% of adipocytes' volume. In order for this storage of potential energy (60,000-100,000 kcal) to be used and to LOSE BODY FAT (everyone's goal), it must be mobilized through lipolysis (the breakdown of triglycerides).

Lipolysis involves splitting the triglycerides into a glycerol molecule and 3 separate fatty acids (FFA). Once the fatty acids diffuse (exit) from the adipocytes, they bind to plasma albumin (in chinese 白蛋白, a protein in the blood) in order to be transported to active tissues where they can be burned. In order to lose body fat, the fatty acids must be burned! (This is why we need constantly have sufficient protein to body thus to help you reduce fat and increase lean muscle)

Transport Of FFA To Be Burned!

Blood flow is of prime importance to the transportation of FFA away from adipocytes and through the circulation to active tissues where they can be burned. This is especially important during exercise where energy requirements are heightened.

Low blood flow could cause the accumulation of FFA within adipose tissue resulting in less available FFA to be oxidized and a greater chance of FFA to be turned back into triglycerides. What is the best way to increase blood flow? Exercise! (This explain why you eat protein only won’t reduce your fat, and you trust slimming without exercise is nonsense.)! In addition to this certain supplements can also increase blood flow (eg: Caffein). Increasing blood flow throughout the body will assist in losing weight by transporting FFA to where they can be burned. (And this is the reason why exercise make you slim down. The more you move, the more FFA burned)
