I first became familiar with the brilliant Dr. William Davis and his impressive body of work when I interviewed him for an episode about heart attacks way back in 2009.

Later, he joined me for a podcast about his book Wheat Belly, in which we discussed why you're not eating the same kind of wheat your ancestors ate, whether wheat bread is really better than white bread, if wheat is ever OK to eat and if so, when, and good substitutes and alternatives for wheat.

Today, Dr. William Davis is back to discuss his new book Super Gut: A Four-Week Plan to Reprogram Your Microbiome, Restore Health, and Lose Weight. In Super Gut, Dr. Davis takes his research and findings a step further and shows that because of our highly processed diet, pesticides, and overuse of antibiotics, our guts are is now missing so many of the good bacteria required to be healthy. As a result, many of us have lost control over health, weight, mood, even behavior.

The ancient bacteria that keep our gut in alignment and our digestion easy have been dying off, replaced by harmful microbes that don’t serve to keep us physically healthy and mentally fit. With cutting-edge research, Dr. Davis has connected the dots between gut health and modern ailments and complaints. There are entire species of microbes that have disappeared, creating health issues that were uncommon one hundred, or even fifty, years ago. A major consequence is SIBO (Small Intestinal Bacterial Overgrowth), a silent and profound epidemic, which affects one out of three people and is responsible for an astounding range of human health conditions.

Super Gut shows how to eliminate bad bacteria and bring back the missing “good” bacteria with a four-week plan to reprogram your microbiome based on research and techniques that not only get to the root of many diseases but improve levels of oxytocin (the bonding/happy hormone), brain health, and promote anti-aging, weight loss, mental clarity, and more restful sleep. Super Gut explains the science clearly and includes more than forty recipes, a diet plan, and resources so you can pinpoint your gut issues, correct them, and maintain your long-term health and well-being. Dr. Davis provides solutions to health problems by addressing the microbiome, massively disrupted in modern people. He shows readers in his Super Gut book, for instance, how to restore important lost microbes lost such as Lactobacillus reuteri, restored by using a unique method of yogurt fermentation that smooths skin and reduces wrinkles, restores youthful muscle and strength, deepens sleep, reduces appetite and provides many other youth-preserving and anti-aging effects. In Super Gut, he provides additional do-it-yourself-at-home strategies for benefits such as improved mood, improved athletic performance, better sleep, heightened immunity, and improved body composition.

Dr. William Davis is also responsible for exposing the incredible nutritional blunder made by "official" health agencies: Eat more "healthy whole grains." The wheat of today is different from the wheat of 1960, thanks to extensive genetics manipulations introduced to increase yield-per-acre. Eliminating wheat yields results beyond everyone's expectations: substantial weight loss, correction of cholesterol abnormalities, relief from inflammatory diseases like arthritis, better mood, reduced blood sugar with many type 2 diabetics being freed of insulin and other drugs, all articulated through his Wheat Belly series of books. He is also a champion of individual self-directed health, as discussed in his Undoctoredbook.
