As far as the HFCS item the issue may be in the way your body metabolized Fructose. Most sugars are utilized directly by the muscles when exercising, and what is not used is converted to fat. In the case of fructose it is metabolized by the liver and converted into usable energy, i.e. fat. This is why eating fruit doesn't give you the sugar rush that glucose gives you, Glucose is raw energy and ready to be used by the body, fructose is more of a slow release, as the liver can only work so fast.
I would venture to guess that by the time the liver finishes with the Fructose most of it is going directly to fat as the body is inactive.

1. fructose can be converted into glucose (fructose, to fructose 1 phosphate, to glyceraldehyde 3 phosphtate, to fructose 1 6 bisphosphate, to fructose 6 phosphate, to glucose). once converted to glucose, it can be metabolized in the same way that all glucose is.
2. fructose can be metabolized directly by muscles as they have an enzyme, hexokinase, that the liver either does not have, or has it insufficient quantities (depending on the text you read, and whether or not it's about biochemistry or nutrition)... both fructose and glucose are "raw" energy.
