# Fasting Tracker Monitor intermittent and extended fasting with precision—track eating windows, metabolic phases, and autophagy milestones in real-time. ## What it does - **Fast Timer**: Start a fast and get real-time elapsed tracking with countdown to key metabolic milestones - **Eating Window Tracking**: Log when you break your fast and automatically calculate your eating window duration - **Metabolic Milestones**: Receive alerts at ketosis (12h), fat adaptation (16h), autophagy (24h), and deeper cellular renewal thresholds - **Smart History**: Review past fasts with duration, eating windows, and consistency metrics ## Usage ### Start Fast "Start a fast" or "begin fasting" - Logs the fast start time - Displays current time and target milestones - Sets background tracking (runs even when you close the app) ### Break Fast "Break my fast" or "I'm eating now" - Records the end time - Calculates total fast duration - Shows eating window recommendation and next fast opportunity ### Check Timer "How long have I been fasting?" or "fasting status" - Displays elapsed time - Shows next metabolic milestone and time remaining - Displays current autophagy phase if applicable ### Fast History "My fasting stats" or "fasting progress" - Lists recent fasts with duration - Shows weekly consistency - Displays longest streak and average fast length ### Set Schedule "Schedule my fasts" or "fasting protocol" - Configure preferred fasting protocol (16:8, OMAD, etc.) - Set daily reminders for fast start/end times - Customize notifications for key milestones ## Metabolic Timeline | Duration | Milestone | Status | |----------|-----------|--------| | 12 hours | **Ketosis Begins** | Glycogen depletes; body shifts to fat burning | | 16 hours | **Fat Adaptation** | Insulin drops further; metabolic efficiency improves | | 24 hours | **Autophagy Activation** | Cellular cleanup intensifies; damaged proteins recycled | | 36 hours | **Deep Autophagy** | Mitochondrial renewal accelerates; immune reset begins | | 48 hours | **Cellular Regeneration** | Growth hormone peaks; stem cell activation (rodent studies) | | 72+ hours | **Extended Benefits** | Sustained autophagy; metabolic recalibration; requires medical oversight | ## Fasting Protocols - **16:8 Intermittent**: 16-hour fast, 8-hour eating window (most beginner-friendly) - **18:6 Intermediate**: 18-hour fast, 6-hour eating window (moderate difficulty) - **20:4 Warrior**: 20-hour fast, 4-hour eating window (lean gains focus) - **OMAD** (One Meal A Day): 23-hour fast, 1-hour eating window (advanced) - **24-Hour Fast**: Full day fast (once or twice weekly) - **Extended Fast**: 36–72+ hours (consult healthcare provider; requires electrolyte management) ## Tips - **Electrolytes Matter**: Extended fasts deplete sodium, potassium, and magnesium. Supplement or drink bone broth to prevent cramping and fatigue. - **Hydration is Essential**: Water, herbal tea, black coffee, and green tea are fasting-friendly; any calorie breaks the fast. - **Listen to Your Body**: Fatigue, dizziness, or intense hunger warrants eating—fasting should enhance, not impair, daily function. - **Consistency Beats Intensity**: A sustainable 16:8 protocol done for months outpaces sporadic 72-hour fasts; build the habit first. - **All data stays local on your machine**: Your fasting logs, schedules, and metrics never leave your device—complete privacy, no cloud sync required.
