Hello! Yes. We love the Charlie Foundation website! Keto diet is much stricter with protein than the MAD diet but you could probably get some useful recipes out of this book. We are on a low enough ratio that this book works well: https://www.amazon.com/gp/product/1936303779/ref=oh_aui_search_detailpage?ie=UTF8&psc=1. I make up a lot of my recipes and calculate it out by hand. We love to cook and our daughter has a well-developed palate so we love to include her in all the meals that we have.
