Intermittent fasting is one of the most researched and effective approaches to weight management, metabolic health, and longevity — but most information online is scattered or tied to a product.
We built FastingInPractice to fix that. Our goal is to be the most complete free resource for intermittent fasting on the internet.
Every article draws from Intermittent Fasting in Practice, a comprehensive guide covering everything from basics to extended fasting, women's health, diabetes, exercise timing, mindset, and more.
Available in 23 Languages
FastingInPractice publishes science-backed articles and summaries of high-quality intermittent fasting research in 23 languages — including English, Farsi, Portuguese, Italian, Korean, Hindi, Arabic, Japanese, Polish, Ukrainian, and more.
Every article is carefully translated so that anyone, anywhere can access accurate fasting information in their own language. Our mission is to make fasting science truly global — free and accessible regardless of where you live or what language you speak.
