Robb Wolf is a former research biochemist and is one of the leading thinkers/writers/practitioners in the Paleo or Ancestral Health movement. The essence of this book is the that while there are general principles of nutrition that work for everyone AND... Ultimately we need to figure out what works best for us as individuals if we want to rock it. Big Ideas we explore include: the fact that one size diets do NOT fit all (remember: "rough" tools vs. precision tools), discordance theory (there's a mismatch between our genes and our environment!), an anti-inflammatory diet (aka Paleo aka Phase I), personalized nutrition (aka 7-Day Carb test aka Phase II), the other pillars of health (sleep, stress, move, connection), and genetic + environmental lotteries (what to do if you lost them--lol).
