Currently, Peter is the president and co-founder of the Nutrition Science Initiative (NuSi), a non-profit organization whose goal is to reduce "the economic and social burden of obesity and obesity-related chronic disease by improving the quality of science in nutrition and obesity research". A lofty but very much needed goal bearing in mind that the official advice on nutrition dispensed by most medical professionals and mainstream organizations (e.g. American Heart Association) is based on shoddy science, really great marketing, and some superb political moves.
Now, why do I think that Peter is a star of the low-carb world? It's because he has explained nutritional ketosis so well. The nutritional ketosis is on the lowest end of the low-carb range - a metabolic state that keeps me in my optimal health zone. To see if you may benefit from ketosis, take Peter's Ketosis 101. However, I must warn you. It is not an easy read. So, if you prefer something in a lighter format, watch the interview with Peter Attia below, courtesy of Andreas Eenfeldt.
