Hi! I am a Professor of Nutrition based in Chicago. I'm one of the first scientists to study intermittent fasting, and I’ve been doing it for over 20 years. If intermittent fasting has ever felt confusing or overhyped, don’t worry — I’m here to break down the science, share insider tips, and give you the latest research so you actually know what works.

On this channel, you’ll find evidence-based guidance on intermittent fasting, weight loss, metabolism, longevity, and overall health. 

I cover topics like:
• Intermittent fasting for beginners (16:8, OMAD, extended fasting)
• Fat loss and metabolism optimization
• Longevity, and anti-aging science
• Hormones, insulin resistance, and blood sugar balance
• Nutrition myths debunked with real research
• Best foods to eat while fasting and how to break a fast
• Exercise, fasting, and performance
