Sorry, Glycogen Loader.

Well, it's still a carb-based diet, but 10% fat is starting to get into the 
loading range.

  >I realize that the amount of this diet fed, relative to the 
 total diet (including roughage), is what important (I think I've read in 
 Lew Hollander's book that 10% of the TOTAL diet is needed for fat 
 loading?).  I have no clue as to how much grass my horse is eating, so I 
 cannot estimate his total diet, but it is obvious that if the concentrate 
 portion is 10% fat then the percent fat in the total diet must be much, 
 much lower.  Rice bran is 20% fat, but my guy does his best to sift it 
 out of what he eats, so that does not add substantial fat to his diet.  
 At 800 lbs, carrying a heavyweight rider, I must put a lot of energy in 
 to keep him from being thin.  How do I achieve the proper amount of fat 
 to supply intramuscular triglycerides?>

In theory, first by using a low fat diet in training and challenging the fat 
supply. Then by loading fat and causing supercompensation of myscle 
triglyceride stores. What it takes to accomplish this in a horse is unknown. 
In humans, a up to a 40% fat diet is 
used.
