Very interesting.

So, for an endurance athlete (say an Ironman distanct triathlete) attempting
to follow a paleo diet, what could be relied upon to replenish muscle
glycogen quickly following long duration workouts?

Subject: fruit and glycogen

Individuals trying to replenish muscle glycogen using sources of fruit
will
typically find this doesn't work very well as fructose (fruit sugar) is
used
to preferentially replenish liver glycogen.  The liver can store
approximately 60-100 grams of glycogen and once this is full any
additional
fructose suppplied by fruit intake will be converted to fat with muscle
glycogen largly unaffected.  The bottom line is that fruit is a good
source
of immediate energy and a couple of pieces per day can be used to keep
liver
glycogen stores full but it's a poor source of long term energy for
athletes
and others who need full muscle glycogen stores.  This makes sense when
you
think of how fruit occurs in nature...quite convenient and can be eaten
quickly.
