Comment: Mark sisson has fat burning

Mark sisson has fat burning genes that not everyone has. But we are all carbohydrate burners. And mark sisson releases lots of photos of him in his prime.

its easy for a fat burner to preach high fat high protein low carbohydrate diets.

Fat burners are those people who just can't seem to gain weight and stay lean and fit. Those are people who's genes burn fat more efficiently. I have a freind like this he eats like crap all the time but he loses weight easy and stays slim.
