You guys have been requesting today's guest for a while now. Dr. David Perlmutter is a board-certified neurologist and the author of the terrifically titled, #1 New York Times Bestseller, “Grain Brain: The Surprising Truth about Wheat, Carbs and Sugar - Your Brain's Silent Killers.” This show was a ton of fun for me personally, and is chock-full of awesome information. On the show we talk about: The surprising reason you should be eating more cholesterol. How eating fat makes you smart. The brain-building effects of musical training. The 2 things you can do right now to literally regrow your brain. Big news and updates: The Fat-Burning Man Show managed to break iTunes charts and get BOTH the audio and video podcasts in the TOP 10! Thank you as always for the amazing support. If you have a moment, we would love it if you left a review! As if that wasn't already exciting enough, we also released The Fat-Burning Chef this week! Be sure to head to the Facebook page as well for a whole bunch of giveaways.   #Ketogenic diet can actually lead to mitochondrial biogenesis.
