carnitine or L-carnitine has become a popular fat burner ” between both fans the fitness between people seeking to get rid of those love handles. And the blogosphere has helped in part to spread another myth, because while there are some that are beginning to qualify their real effects and indicate that without exercise is totally ineffective (as it would happen with any other supplement), they are very few who pull of scientific studies and telling the truth: carnitine is totally useless for weight loss.
But start from the beginning, which is the carnitine?
Carnitine is a compound derived from lysine and methionine (amino acids) found in the cells. To be precise, is located in the mitochondria, a species of small cells for thousands of years our cells had and that we would have a relationship of symbiosis ”. For us, the mitochondria will be the burner ” or furnace ” where the fat must be burned (or rusty). how it works?
Clarify that does not burn the fat ”, that is handled by a process called beta-oxidación and that occurs in the mitochondria. What carnitine is to transport the fat ”, because you need this transport? because the mitochondria have two membranes that the fat have to pass through to reach inside. This substance is transported the grease from the outer to the inner layer, but does not control its entry or its consumption, that are responsible for the goalkeeping ”.
The obvious conclusion would be to more carnitine, transported more fat. This is not true, because? because hardly may carry more fat if the goalie ” not let these come. These porters if you’re curious to know what are the CPT-I and CPT-II and so far, any mechanism that encourages the entry of more fat in mitochondria is not known, that is to say, the carnitinas can not carry more fat because the CPT-I and CPT-II will not allow that you among more fat.
does that mean that supplementation is useless? the answer in the next post, but already slimming advancement that does not serve.
