Fasting Path is the simplest way to start intermittent fasting - and the most rewarding way to stick with it. Whether you're brand new to intermittent fasting or you've been doing 16:8 for years, Fasting Path turns your fast into a clear, science-backed daily ritual. No clutter. No guilt. No confusing macros. Just a beautiful fasting timer, real progress tracking, and a community that's fasting alongside you. A FASTING TIMER THAT JUST WORKS Tap once. Your fast begins. Our circular fasting timer shows your real-time progress, current metabolic phase, and eating window countdown - so you always know exactly where you are in your day. 8 INTERMITTENT FASTING PROTOCOLS Pick the intermittent fasting schedule that fits your life: - 16:8 - the classic, perfect for beginners - 18:6 - the next step up - 20:4 - the Warrior Diet - OMAD - One Meal A Day (23:1) - 24-hour fast - 36-hour extended fast - 48-hour deep fast - Custom - set any window you want FAST WITH FRIENDS (OR THE WORLD) Fasting alone is hard. Fasting together is fun. Create a private group with friends and family, or join a public group and chat with thousands of fasters in real time. Group fasting is about support, not competition - celebrate streaks, share wins, and lean on the community when day three gets tough. LEARN THE SCIENCE OF FASTING Our knowledge library translates the research into plain English. Discover what's actually happening in your body during your fast: glycogen depletion, ketosis, autophagy, growth hormone release, and the metabolic switch. Topics include: - Hour-by-hour: what happens during a 16:8 fast - Autophagy and cellular repair - How to break a fast safely - Mental clarity, focus, and fasting - Hydration, electrolytes, and water fasting - Real success stories from real fasters BADGES AND STREAKS THAT KEEP YOU GOING Earn achievement badges for every fast, every milestone, and every streak. Climb from Bronze to Silver to Gold to Platinum. Track your total fasts completed, longest fast, and current day streak - small wins that compound into big results. NOTIFICATIONS THAT HELP, NOT NAG Get the right tip at the right time: a hydration nudge at hour 8, a metabolic milestone at hour 12, gentle encouragement at hour 16. Quiet by default - you control everything. YOUR PERSONAL FASTING JOURNAL Log your mood, energy, and notes after every fast. Spot patterns over time. Export your full fasting history as a CSV - perfect for sharing with your doctor, dietitian, or coach. BOOST WHEN YOU NEED IT Hitting a wall during your fast?
