Okay -- so, a very simplified answer to DH's question asking if he's not burning the old stored fat while he's riding his bike is "the rest of the time" -- but only if he's not making up for the burning by napping or eating. Which is NOT exactly what to tell him, since he's a bit goofy about eating anyway...

But it's GOOD to eat a bit now and then while riding for a few hours because that keeps him from using muscle tissue as fuel if he runs out of glycogen, yes? Because if he uses the muscles as fuel while riding, then there's no muscle to burn fat the rest of the day, yes?

This has to be simple, and extremely logical for him... (maybe for me too, aside from the logic part) (somehow, I'm getting it: I have holes in my fat padding lately!)
