Hormonal Regulation of Metabolism in the Absorptive State, -4 hrs after a meal, abortion is nearly complete, blood glucose level starts to fall b/c glucose continues to leave bloodstream & enter body cells (while none is being absorbed in GI tract). There are three main metabolic states of the body: absorptive (fed), postabsorptive (fasting), and starvation. reactions of the absorptive state are mainly ANABOLIC. Metabolic changes toward the fasting state begin after absorption of a meal (typically three to five hours after a meal); “post-absorptive state” is synonymous with this usage, in contrast to the “post-prandial” state of ongoing digestion.
