Let's Talk About fat burners
July 2nd 2009 11:41
There are many products on the market today that offer ingredients that are advertised to "BURN FAT." Let's examine the cold, hard facts. This is going to get a little technical, but it is the only way I know to explain fat burning.
Your cells are composed of cell parts (organelles) that are encased in cell membrane material. Cell membranes are composed of fatty molecules called phospholipids. The Lipid or fat part of the molecule does not like water, whereas the phosphate part of the molecule is water loving. Cell membranes are composed of a phospholipid bilayer with the fatty molecules in the middle and the phosphate groups on the inner and outer surface of the membranes. So a cell is encased in such a membrane, as well as the organelles like the nucleus and the mitochondria. The mitochondria actually have an outer membrane and an inner membrane. These membranes hold proteins that act like gates to screen what molecules get in or out of the structure.
All fat is burned inside the inner mitochondria. Fat molecules have little trouble entering a cell, however getting into the mitochondria is another issue. A fatty acid molecule is activated outside the mitochondrion by attaching to a active molecule called CoEnzyme A. An amino acid molecule called L-carnitine attaches to a fatty molecule as it passes through the outer membrane of the mitochondrion. It then makes its way to carnitine recognition protein in the inner membrane of the mitochondion and is promptly shuttled through to the matrix of the mitochondrion. Once inside the matrix of the mitochondrion the fatty acid can be burned.
The number of mitochondria in a cell determines how much fat can be burned. The number of mitochondria in a cell is a function of aerobic excercise. Mitochondria are the true fat burners so by doing aerobic excersise on a regular basis you can optimize the number of mitocondria in your cells. This will optimize your ability to burn fat. Mobilized fat from fat reserves will be redeposited in other locations like perhaps your blood vessels if it is not burned.
Now, I ask you, does it make any sense that a supplement could magically burn fat? Not unless it could increase the fat-carnitine transport across the mitochondrial membrane. Fat burning DOES NOT OCCUR ANY OTHER WAY or in any other place! Beware of magical "FAT BURNERS." For more detail visit our website below.
