TY - JOUR T1 - BLood glucose and gluconeogenesis in fasting man AU - Felig P, Marliss E, Owen OE, Cahill GF, Jr. Y1 - 1969/03/01 N1 - 10.1001/archinte.1969.00300130075011 JO - Archives of Internal Medicine SP - 293 EP - 298 VL - 123 IS - 3 N2 - Maintenance of blood glucose homeostasis in fasting man requires establishment of a fine balance between glucose production and utilization. Early in starvation, a decrease in serum insulin provides the alterations in substrate concentration and enzymatic activity conducive to augmented gluconeogenesis. As fasting progresses, glucose utilization is reduced as the brain consumes ketone bodies. A concomitant reduction in total gluconeogenesis is brought about by a reduction in plasma amino acid levels, particularly alanine.
