Fasting State | High Yield Topic Biochemistry | Dr. Ankur Jain

What you’ll learn (timeline)

Early fasting (16–18 hours)

Blood glucose maintained mainly by hepatic glycogenolysis
Liver glycogen supports glucose for ~16–18 hours
Muscle glycogen cannot raise blood glucose (muscle uses it for itself)

Fasting up to ~48 hours

When glycogen depletes, liver shifts to gluconeogenesis
Beta-oxidation increases to provide energy for gluconeogenesis
Hormonal shift: Insulin ↓, Glucagon ↑

Prolonged fasting / starvation (48 hours to 2–5 days)

Liver relies more on beta-oxidation
Starts significant ketone body synthesis
Ketones are used by vital organs (especially brain, heart, skeletal muscle) to spare glucose

Perfect for MBBS, NEET PG, INI-CET, FMGE metabolic integration questions.
