FastGlow:Fasting & Body Clock

Track your fast. Understand your body. Lose weight — without counting calories.

FastGlow is an intermittent fasting timer and tracker that shows you exactly what is happening inside your body — in real time. While other fasting apps just count down the hours, FastGlow tracks 6 biological stages and explains the science behind every minute of your fast.

Stop guessing. Start glowing.

── LIVE BIOLOGICAL STAGE TRACKER ──
Every hour of fasting, your body enters a new phase. FastGlow tracks all 6:

● Digestion (0–4h) — body processing your last meal
● Glycogen Depletion (4–8h) — glucose stores emptying
● Ketosis Begins (8–12h) — fat burning starts
● Autophagy Activated (12–16h) — cellular cleanup (Nobel Prize research)
● Deep Ketosis (16–20h) — peak fat burning, mental clarity
● Extended Fast (20h+) — growth hormone surge, immune regeneration

── FASTING PROTOCOLS FOR EVERYONE ──
● 16:8 — the most popular beginner method
● 18:6 — advanced fat burning
● 20:4 — Warrior Diet, deep ketosis
● 24h — full metabolic reset
● Custom — set your own fasting window

── WEIGHT TRACKER WITH PROGRESS CHART ──
Log your weight daily and watch the chart update automatically. Switch between kg and lbs. See your starting weight, current weight, and total change at a glance. Visualize your fat loss journey as your fasting and weight data work together over time.

── BREAK YOUR FAST GUIDE ──
The first meal after a fast is the most important — and most fasting apps ignore it entirely. FastGlow includes a full guide: what to eat in the first 15 minutes, what to eat after 45 minutes, what to avoid and exactly why. Protect your hard-earned results with every meal.

── MOOD & ENERGY TRENDS ──
After each fast, log how you felt: energy level, mental clarity, and hunger. FastGlow charts these over time so you can see which protocol leaves you feeling best. Discover your personal sweet spot.

── DAILY SCIENCE TIPS ──
A new science-backed fasting tip every day — 30 rotating tips with real research sources. Something to learn every day, even on rest days.

── FASTING JOURNAL ──
Write a quick daily note — how you feel, what you noticed, your motivation. All notes are saved privately on your device and shown in your history.

── FASTING STREAKS & MILESTONES ──
Track consecutive fasting days. Celebrate milestones at 7, 14, and 30 days. Your streak is the most powerful habit tool in the app.

── WHO IS FASTGLOW FOR? ──
● Anyone doing 16:8, 18:6, 20:4, OMAD, or any time-restricted eating
● People who want to understand the biology behind fasting, not just track hours
● Health-conscious adults focused on weight loss, longevity, and metabolic health
● Beginners who want a clean, science-backed companion from day one

── WHY FASTGLOW? ──
Most fasting apps are just timers. FastGlow gives you the science, the progress tracking, and the daily guidance that makes fasting a long-term lifestyle — not a temporary experiment.
