Events of the
Absorptive The absorptive state, during which
ingested nutrients enter the blood
and from the gastrointestinal tract, and
Postabsorpti The postabsorptive state, during
ve States which the gastrointestinal tract is
empty of nutrients and the body’s
own stores must supply energy.
, An average meal requires approximately 4 h for complete
absorption, our usual three-meal-a-day pattern places us in
the postabsorptive state during the late morning, again in the
late afternoon, and during most of the night. We will refer to
more than 24 h without eating as fasting.
During the absorptive state, some of the ingested nutrients
provide the immediate energy requirements of the body and
the remainder is added to the body’s energy stores to be
called upon during the next postabsorptive state. Total-body
energy stores are adequate for the average person to
withstand a fast of many weeks, provided water is available.
