Step 1: Assess Readiness and Consult a Doctor
Before starting, understand water fasting: complete abstinence from food, only pure water, typically 24-72 hours for beginners. Review contraindications.
Key Actions:
- Research benefits (autophagy, weight loss, insulin sensitivity) and risks (dehydration, nutrient loss, orthostatic hypotension).
- Check if suitable: Avoid if pregnant, breastfeeding, under 18/over 75, underweight, have eating disorders, type 1 diabetes, heart/kidney issues, or on meds requiring food.
- Schedule doctor consultation: Discuss health history, meds, get baseline labs if needed.
- Start with 24-hour fast if new.
Critical: Medical approval is non-negotiable.
