As for insulin spikes, consider this.  If your diet is generally
low-carb, then your glycogen stores are almost always low.  When
you eat glucose under these conditions, there should be virtually
*no* insulin spike.  This is because insulin is not involved in
the depositing of glucose into glycogen stores.  In short, your
liver and muscles will suck up that glucose very quickly, without
the help of insulin.  Carbs cause an insulin spike only when
glycogen stores are full.  In that case, there's no place for the
glucose to go, but it has to be pulled out of the blood, so it
must be converted to fat, and insulin is required for that.


***Insulin is also required for the deposition and transport of glucose and
amino acids into muscle.  This is the premise behind bodybuilders use of
"cyclical ketogenic diets".  Glycogen is depleted entirely and then when
reintroduced in greater quantities insulin levels are higher then they would
normally be and more glycogen and aminos are deposited into the muscles.
Also it is not uncommon for someone on a prolonged low carbohydrate diet to
go into an insulin induced stupor upon the reintroduction of a large amount
of carbohydrates.  This would seem to indicate that insulin levels are in
fact higher when introducing carbohydrates after a period of carbohydrate
restriction.
