think about it , if you got kids and you see them eat a shit ton of pop and candy or sweets, 30 mins later they are bouncing off the walls full of energy cause they have all that glucose/sugar to burn off for fuel.

glucose is energy, we store this energy in either the liver, muscle, fat, or the blood stream .. and the body utilizes it from these different areas dependent on the demand (e.g... weight training will burn up blood glucose AND muscle glucose/glycogen for energy).

If we are about to do steady state cardio, and we have a fairly decent amount of blood sugar floating around the blood stream to be used as energy, then your body will tap into that glucose for energy and then after that is used up it starts oxidizing fat for energy (it can actually somewhat use both at the same time). so if we go into a non glycogen dependent cardio session with lower blood sugar then we will burn more fat for energy . steady state LISS is a form of cardio that doesn't use glycogen , where as HIIT does . so if you did HIIT cardio then going into it with low blood sugar makes no difference, its just going to use muscle glycogen anyways. going into LISS cardio with lower blood sugar to start will help burn more fat
Great thread GH!

In the Ironman and Ultrarunning community, what you're describing sounds a lot like metabolic efficiency. I've been a lab rat for them in their testing to see what diet and supplements do to improve (or move the point of conversion). I didn't realize slin can induce it so much more quickly.
