The Science

Five phases. One ring.

Most fasting apps stop at "you're hungry now." BellyClock visualizes the full metabolic arc so you know exactly what your body is doing, hour by hour.

Fat-Burn

Stored fuel starts dropping and the body begins leaning harder on fat for energy.

Feeling low energy at hour 14. Should I break?
Your last 5 fasts show a dip here. Try 500ml water with electrolytes. Hydration is at 60% today.
If it persists after 30 min, consider breaking. This usually improves by week 3.
