SUPER Body: A 3-Week Program to Harness the New Science of Body Composition and Restore Your Youthful Contours

by William Davis

Take your health into your own hands by focusing on your overall body composition, microbiome, and the restoration of ancestral foods with this cutting-edge new book from the bestselling author of Wheat Belly and Super Gut.

Forget everything you've been told about dieting (from your doctor, the food industry, wellness influencers, etc.). Too many of us mistakenly believe that calorie restriction, pharmaceutical weight loss drugs, and bariatric procedures are effective solutions for weight loss. However, these “solutions” are plagued by serious problems, including virtually guaranteed weight regain. Muscle mass is what maintains our weight, and it also provides youthful vigor, mobility and overall health. When we diet, any muscle lost is often re-gained as fat, leaving us in worse shape than before. The essential microbes that have also been lost in our diet weakens us in the same way.

In SUPER Body , William Davis, MD reveals how we can restore our bodies through nutrition, microbes, and supplements. The solutions to health, including weight management, do not lie in pharmaceuticals or procedures, but in returning to the natural foods necessary for human life.

Reviews

[BHK · Rating 5 out of 5]

I’ve read a few of William Davis’s previous books like Wheat Belly and Super Gut, and SUPER Body continues his streak of offering eye opening and science backed health advice that actually feels doable. This book is a total mindset shift if you’ve been stuck in the diet culture loop of counting calories or relying on meds and quick fixes. SUPER Body reframes the conversation entirely around body composition, microbiome health, and ancestral nutrition. Davis makes a strong case that real, sustainable health isn’t about losing pounds at any cost, but about rebuilding muscle, healing your gut, and nourishing your body the way nature intended. His three week program is packed with practical guidance, but also dives into fascinating new science that doesn’t feel overwhelming. If you’re tired of fads and want something that actually supports long term wellness, this book is well worth reading. It’s a refreshing, empowering approach that makes you feel like you’re finally working with your body, not against it.

Super Body builds on Williams Davis's familiar approach to health, focusing on metabolic repair, muscle preservation, and long term wellness rather than quick fix weight loss methods. I appreciated the emphasis on strengthening the body from the inside out, especially the focus on muscle, gut health and avoiding strategies that sacrifice long term health for short term results. The three week reset format makes the information given in the the book feel more actionable. Overall, it's a solid read for anyone interested in improving body composition and metabolic health beyond the usual diet trends.

Most of us have heard about probiotics by now. But they we really understand what’s behind them and what Benefits gut health really brings to the body? This book was a great resource for me to understand more and how to get a better hold on my gut health. I actually find it to be fascinating as the doctor is credible, and backs up everything he claims and speaks about with facts and studies. It’s hard to find out these days. But this book delivers, and I’ve already recommended it to several friends.
