<<This seems to illustrate that excess carbo consumption causes torpidity
because of the large amount of energy required to digest it.>>

<<I have the same reaction....eat bread/sleep for a couple of hours......but
I thought it was from the carbs spiking my blood sugar then having a sugar
crash.....makes sense
that it could be caused by so much energy required to digest the
stuff...........>>

Carbs like starches and grains liberate their glucose bonds easily and cause
blood sugar to increase relatively quickly, with a peak at about the 30 to
45 minute level after eating.  The increase in blood sugar normally gives us
energy.  Blood sugar levels don't fall again until 2 to 4 hours after
eating.

If you feel tired after eating, food allergies/sensitivities are likely the
cause.  This is quite common with gluten-containing foods, like bread (I'm
the same way).
