The Whole30 Cookbook

I'm curious whether the recipes were developed specifically for variety or based on popular demand. Did the author have a particular culinary goal in mind for this collection?

Some dishes came together quickly, while others took more effort. I'm wondering if this matches others' experiences or if there's a secret trick to some of these techniques.

The recipes look delicious, but sticking to the program can be tough. Did this cookbook include tips or strategies that really helped others stay on track?
