Carnitine may also help you oxidize your fat ass...
The effect of l-carnitine on fat oxidation
"increased dietary fat oxidation in slightly overweight subjects was not accompanied by protein catabolism."
That's the good news. This too:
"Essentially, transports the chains of fatty acids into the mitochondrial matrix, thus allowing the cells to break down fat and get energy from the stored fat reserves." 1
This could be in part why people who go on a paleo diet lose fat. Not only is the insulin response improved, but with all that extra carnitine, the fatty acids are being burned more efficiently.
