Timers are easy to ignore when hunger spikes. A private streak is easy to reset without telling anyone.
18-hour fast accountability means witnesses. Your group completes their windows — you see their streak when you are tempted to break yours early.
The rule is simple: no caloric food or drink until eighteen hours pass. Water, black coffee, and plain tea are fine. Then check in honestly.
LetBeMe is built for daily habit loops, not medical coaching. Use the Fast 18-21 challenge for a structured start with a finish line.
Hold your window today. Check in yes before you eat.
