This is where it all begins. Well, for me it was actually Melissa and Dallas Hartwig's first book, It Starts With Food, but that's more of a nutrition book than a cookbook so it's not on this list. The Whole30 book is an upgrade from that, with even better meal planning and cooking resources. No doubt that the official Whole30 Cookbook, which was released in 2016, is also a good one to keep in your kitchen. I'd like to get my hands on that one soon. Buy it here.
