Frequently Asked Questions — Intermittent Fasting Calculator
What is the best intermittent fasting schedule for beginners?+
14:10 or 12:12 are the best starting points. They align with natural overnight fasting and are easy to maintain. Once comfortable, progress to 16:8 after 2–4 weeks.
Can I drink coffee during intermittent fasting?+
Yes — black coffee, plain tea, and water are allowed during fasting. They contain zero calories and may even enhance fat burning. Avoid milk, cream, sugar, or sweeteners.
