The Best Fat Burner You've Never Heard About

The Best Fat Burner You've Never Heard About


Spending tons of money on supplements is great, and if you agree with that statement, then this article may not be for you. You see, I prefer to spend as little as possible on supplements, so the money I do spend is definitely going to be on a supplement that is going to benefit me a lot.

In the past L-Carnitine has been on the receiving end of quite a bit of poo-pooing by those who tried it and didn’t immediately turn into a fitness model. I believe these folks, and their claim that L-Carnitine did not work for them the way they expected, but the same can be said for jumping into a Lamborghini and not being able to drive a stick. A great product, not used properly, makes for crappy results. 

Approximately 95% of the body’s carnitine is located in skeletal muscle. Carnitine is a substrate for an enzyme which is a rate limiting step in fatty acid oxidation in the mitochondria.

A recent study has shown that when total muscle carnitine content is increased, body fat mass accrual associated with carbohydrate supplementation was prevented. 

In the study 2 groups of healthy males were given 80g of carbohydrates (control group) or 80g carbohydrates with 1.36g of L-carnitine (carnitine group). Each group supplemented 2 times a day for 12 weeks.

The research concluded that not only was carnitine responsible for preventing fat gain in the carnitine group vs. the control group, but also that the prevention of fat gain was associated with an up-regulation of genes and gene networks relating to fuel metabolism.

They also found an increase in energy expenditure and fat oxidation during low intensity exercise (<50% of max oxygen consumption). In this particular study, after 12 weeks of L-carnitine and carbohydrate supplementation, muscle total carnitine increased by 20% Long-chain acyl-CoA increased by 200%, and whole-body energy expenditure increased by 6%1.

Here are some things that you can do to take advantage of L-carnitine:

  • The doses used in the studies averages about 3g L-carnitine per day.
  • The studies were conducted over 12-24 week periods. So be patient. 
  • Take your L-carnitine with carbohydrates. Carbohydrates spike insulin, and insulin as a nutrient driver helps load the muscle with carnitine at a faster rate than ingestion of L-carnitine alone. If you use an intra-workout drink, that would be a pretty good opportunity to take advantage of increased carnitine uptake by spiked insulin levels. 
  • Weight train. Why not burn a higher percentage of fat during your training, and retain a fuller look to the muscle by sparing muscle glycogen? 
  • Cardio. I realize the huge debate between steady state and HIIT cardio. Consider for a second that if you do your HIIT first and then just cruise ats a nice slow steady pace of a little while after, you could take advantage of the EPOC from the HIIT, and also the higher amount of fat oxidized while you walk due to your new friend L-Carnitine.
