Absorptive state is the period in which the gastrointestinal tract is full and the anabolic processes exceed catabolism. During this interval, transient increases in plasma glucose, amino acids, and triacylglycerols (TAG) occur, the latter primarily as components of chylomicrons synthesized by the intestinal mucosal cells (see p. 228). People have an overall metabolism that differs from the metabolism of individual cells. The absorptive state in trance relates to the hyper-focused immersive experience of flow (Csikszentmihalyi 1990) and has been cultivated in many musical and contemplative traditions (Harner 1990; Becker 2004; Walsh 2007).

The absorptive state lasts for four hours, during and after each meal. During the absorptive state, the stomach and intestines contain nutrients that are being absorbed by the body. There are metabolic pathways which form a two-part process; the first part is the one mentioned called, 'Catabolism,' during which the body processes food to use for energy. Triglycerides - Chylomicrons, the main product of fat digestion, are first broken down to fatty acids and glycerol through hydrolysis using Lipoprotein lipase.

The presence of villi in the intestine helps in the process of absorption after the digestion of the food is completed. The glycogen and fat will be stored in the liver and adipose tissue, respectively, as reserves for the post-absorptive state. The main components through which the nutrients can pass include the blood and lymph. The post-absorptive stages of metabolism occur from the lipid absorption in the intestines.

The following reactions dominate during the absorptive state (Figure 25.17): O About 50% of the glucose absorbed from a typical meal is oxidized by cells throughout the body to produce ATP via glycolysis, the Krebs cycle, and the electron transport chain. Following a glucose load, the body assumes an absorptive state, and its metabolic profile is primarily regulated by insulin. The absorptive state, or the fed state, occurs after a meal when your body is digesting the food and absorbing the nutrients (anabolism exceeds catabolism).
