About the Author

P. D. Mangan is the author of Dumping Iron and, five years after it, of the peer-reviewed paper Iron: an underrated factor in aging, published in Aging in 2021. It sets out the scientific case this book was built on, and you can read it in full on this site.

Since 2015 he has partnered with private clients 1-on-1, through more than 1,700 transformations with men, women, and couples, across 71 countries. They get lean, fit, and strong on one hour of training per week, without starving themselves. The mission of his coaching practice is the one this book points at: fix the metabolic health underneath, so the years ahead come with more energy, a dramatically lower risk of chronic disease, and a longer healthspan to enjoy it all in.

His clients describe the experience in their own words on Trustpilot. He writes about iron, strength, and metabolic health on X at @Mangan150.
