Before you begin
IQFasting shares general wellness information, not medical advice. It does not diagnose, treat, or replace a qualified professional.
Do not use prolonged fasting if you are pregnant or breastfeeding, under 18, have diabetes, an eating-disorder history, are underweight, or take medication — without consulting a clinician.
Stop and seek care if you feel faint, have a racing heart, severe weakness, or anything unusual. You use this app at your own discretion.

Understand the practice
No account. Your data stays here.
IQFasting runs entirely in your browser. Closing the tab and reopening it later picks up where you left off. There is no signup wall, no analytics that identify you, no record of your fast on a server somewhere. When you want a copy, you can export the whole dataset to a JSON file from the Track tab.
Why people fast
Many use intermittent fasting to simplify eating, support metabolic health, and feel sharper through the day. Research suggests benefits around insulin sensitivity, cellular cleanup, and inflammation when fasting is paired with nutritious meals and good sleep — though individual results vary widely.
Intermittent vs prolonged
Intermittent fasting (typically 12–18 hours daily) is widely considered sustainable for healthy adults. Prolonged fasts (24h+) trigger deeper changes like increased autophagy and ketone production, but they also carry more risk and benefit from professional guidance, especially after the first day.
The basics that matter most
Hydrate well. Salt your water lightly on longer fasts to support electrolytes. Sleep enough. Move, but don't grind. Break fasts gently — small, mineral-rich foods first, then build back up. Listen to your body louder than any timer.
When fasting is not for you
If you are pregnant or breastfeeding, under 18, underweight, have diabetes or an eating-disorder history, or take medication that depends on food, talk to a clinician before fasting. There is no badge of honor in pushing through real warning signs.
