Volume I — The Fasting Clock

A large-print, 147-page illustrated guide to the body’s first 24 hours without food. Explore the fuel switches, insulin, the liver, breaking a fast, and what fasting after 60 can and cannot do. Includes a gentle four-week plan from 12:12 to 16:8, plus routine cards and clear guidance on who should not fast.

Educational content only; not medical advice. Fasting may not be appropriate for everyone. Talk with your clinician before changing your eating pattern, especially if you take medication or have a medical condition.
