I know this is really a dumb question, and probably falls in the category of a little knowledge is a dangerous thing, but:
If the only carbs one ate was from fruit (fructose), and
if fructose makes a 'b-line' directly to the liver to be metabolized into glycogen,
does that mean the muscles are not getting enough glucose to fuel their needs?
Could that contribute to any issues with muscle cramps?
Just taking a shot in the dark since pretty much all my carbs are fruit carbs, and I'm having muscle cramp issues.
