Mark Sisson, one of the original advocates of the primal/ancestral approach to eating, and subsequently a promoter of the Keto diet, is coming out with his latest book next month: Two Meals a Day - The Simple, Sustainable Strategy to Lose Fat, Reverse Aging, and Break Free from Diet Frustration Forever.
This book represents the evolution of Sisson’s thinking about the best approach to diet. While he stays consistent with the idea of eliminating foods that would not have been recognized by our ancestors (i.e., sugars, processed grains, and industrial seed oils like corn & soybean) and the benefits of Keto for metabolism, this book is focused on the concept of being more flexible with what we eat but eating less frequently. Specifically, by restricting our eating window through the elimination of one meal per day (Mark skips breakfast). He calls it “intermittent eating,” to take the bite away from the idea of fasting and the growing enthusiasm for OMAD (One Meal A Day).
The key takeaway is to make sure we give our bodies the chance to perform the necessary processes of DNA repair, cell maintenance, autophagy, and boosting of the immune system, which only happen when our bodies are not busy digesting. The book guides you through how to get comfortable cutting out that one meal a day, experimenting with the foods that most suit you, and adopting a more positive mindset towards food and exercise.
