Reserve my spotFor 23 years I kept trying to fast, but most of the time I would stop around the second day. Then a serious infection forced me to search for a way — and lab tests showed the infection drop from over 100,000 to zero, naturally.
The 40-day water fast I completed in 2025, at home while continuing to work, came at the end of a gradual path built over time through patient practice — not overnight. That experience, together with my PhD in food technology and over 12 years of nutrition research, is the foundation of everything I share today.
