Webb31 aug. 2024 · Felig, a researcher who has a handful of published studies on fasting, summarizes the path to ketogenesis in three stages: Stage 1 — The postabsorptive phase — 6 to 24 hours of fasting During this phase, most energy is provided by glycogen. Stage 2 — The gluconeogenic phase — 2 to 10 days of fasting Webb2 mars 2024 · This is a complex, energetically costly process that can’t just randomly be replicated in a metabolic pathway. Also, it contradicts the basic logic of gluconeogenesis; the goal of gluconeogenesis is not to produce energy for the cell but to increase the blood glucose level that’s circulated in the bloodstream.
