Every month, Dr. Katie Deming, MD guides a 3-day water fast — a simple, powerful reset for body, mind & spirit. Daily coaching, real community, and a body that remembers how to heal itself.
A 3-day water fast is one of nature's oldest healing tools. When you stop digesting, the energy your body spends on food goes toward repair instead — clearing out damaged cells, calming inflammation, and quieting the constant noise around food.
Dr. Katie does a 3-day fast every single month, and each month she invites you to do it with her. Same page, same rhythm — because a reset works best when it's a practice, not a one-time event.
“This is not about restriction. It's about creating conditions for your body to function the way it was designed to — and to heal and repair itself.”— Dr. Katie Deming, MD
Three days is long enough to trigger a true metabolic reset — and short enough to repeat every month while living your life.
Insulin falls, glycogen empties, and your body switches to burning fat for fuel. By day three you're in deep ketosis — blood sugar stable without food, proof of real metabolic flexibility.
Around 36 hours in, your growth pathways quiet down and maintenance pathways switch on. Damaged cell components are broken down and recycled — your body's own deep-cleaning program.
Fasting gives your digestive system a complete rest and lowers inflammation — often visible in clearer skin, calmer joints, and easier digestion in the days that follow.
By day three, cravings lose their grip. Sugar stops running the show, decision fatigue lifts, and many people feel calm and neutral around food for the first time in years.
Growth hormone rises during a water fast, signaling your body to preserve lean tissue while it burns fat — especially the visceral fat around your organs.
Ketones are a clean fuel for the brain. Mental clarity sharpens, emotions surface and release, and many describe feeling more connected, embodied, and spacious.
Each day unlocks a deeper stage of the reset. Here's the journey you'll take — with coaching at every step.
Insulin drops and your liver releases stored glycogen. Hunger comes in waves — usually habit, not need — and typically passes in 20–30 minutes. Fat-burning begins.
Glycogen runs out and your liver turns fat into ketones — your brain's new fuel. Hunger fades. Around hour 36, autophagy switches on and repair mode takes over.
You're running on fat and ketones. Growth hormone protects your muscle, cellular cleanup intensifies, and mental clarity peaks. You finish in a different metabolic state than you started.
Breaking the fast well matters as much as the fast itself. You'll get clear guidance on mindful re-feeding so the benefits carry forward into your month.

Dr. Katie Deming is a Duke-trained radiation oncologist who practiced conventional medicine from 2006 to 2022 and treated more than 5,000 patients. After two decades inside the system, she left Western medicine to explore what truly makes people well — and that search led her to water fasting.
Today she guides people through the full spectrum of water fasting, pairing rigorous medical knowledge with deep care for the emotional, mental, and spiritual sides of healing. And every month, she fasts right alongside you.
Water fasting has a remarkable safety record when done properly — and the guided format exists so you never have to figure it out alone. Hydration, electrolytes, and mindful re-feeding are all covered in the guide and the daily calls.
