This book almost begs skimming because it is so full of medical and nutritional details. Gundry tries to be humorous with his references to gut-buddies and he may even be 100% correct with deductions, but when you finally get to the specific recommendations, it is a tad overwhelming.

Eat once a day. Take a few dozen supplements. Get a dog (though I like this one). Only eat fruit in the summer. Give up tomatoes. And on it goes. He even knocks the Blue Zones where people live longest.

There are critics of his approach to eliminating lectins from one's diet. This would take a lot of work and attention to detail.
