Keto Flex Revised

The Advanced Guide to Metabolic Flexibility, Fat Burning, and Hormone Health for Every Body at Every Stage
From New York Times bestselling author of Metabolic Freedom and founder of Keto Kamp, a newly updated and revised science-backed guide for long-term fat loss, metabolic healing, and real-life flexibility through advanced keto made simple.

New York Times Bestseller!

Following the breakout success of Metabolic Freedom, Ben Azadi delivers the next step in his metabolic health revolution with Keto Flex Revised—a clear, customizable, and science-rooted roadmap to long-term fat loss, hormone balance, and cellular healing through the strategic use of ketogenic nutrition and fasting.

Designed for both keto newcomers and experienced biohackers, this updated edition reframes keto not as a rigid diet but as a flexible metabolic tool, guided by Azadi’s signature four-pillar system. With deep roots in ancestral health, Azadi walks readers through the truth about fat-burning foods, how to avoid hidden inflammatory ingredients, and why keto should look different for women, athletes, and anyone dealing with blood sugar, autoimmune, or hormonal challenges.

The book includes:

• Personalized plans for achieving metabolic flexibility
• Guidance on combining keto, fasting, and carnivore safely and effectively
• Hormone-specific protocols (including for cycling, peri-, and post-menopausal women)
• Tools for testing, troubleshooting, and personalizing your results
• More than 50 fat-burning recipes and food lists
• A comprehensive guide to “keto flexing” for sustainable, long-term success
