Glycogen is a long-chained polysaccharide...in essence long-chained form of glucose that is created and stored in the liver primarily and skeletal muscles. As you know skeletal muscles are the ones that respond effectively to exercise. Glucose is already in a usable form...glycogen is the stored form of glucose. Glycogen is broken down (via a series of complex chemical events) back into glucose.
Glucagon on the other hand is a hormone secreted by the pancreas that raises blood glucose levels. Glucagon is also the trade name for an emergency drug used to reverse hypoglycemia in diabetics. Glucagon works in opposition to insulin as they both help to regulate healthy levels of blood sugar. Glucagon does nothing to fat stores in the body...as adipose tissue has very little receptors to both insulin and glucagon. I'm sure you did not want to mislead anyone.
But I do agree as a nurse, I'm pretty strong..has anyone ever rolled a 300lb dead weight person over to change their sheets?

This is the difference between a nurse's understanding of the human chemistry, and a trainer's. This is how the information came from the training manual at NASM (National Academy of Sports Medicine) which is where I got my cert through. Apparently it's not as medically accurate as it should be. I'll add that into my notes in my manual for future reference.
No, i don't want to mislead anyone. I don't like the idea that the information i was trained with was inaccurate, so I'm adding this into my manual for later reference - thanks for the correction.
but i still think the model works as a baseline explanation - exhausting available stores of ready-made fuel creates the need to convert stored fat back into usable energy, and limiting the easier pathway of converting simple carbs to glucose will cause the body to draw on the fat stores to create.
As for the more accurate description - i stand corrected. I suspect that personal trainers don't need the same expertise nurses do in this area - this is why the info we have isn't as accurate.
there you go - sorry about the inaccuracy. I wasn't trying to mislead.
