It has only taken us nearly three years to get around to it, but we’re finally doing our first “Ask Me Anything” episode. It’s hard to believe, but Ken and Dawn sat down to interview their first STEM-Talk guest back in 2016. And during that time, listeners have been emailing us questions. So, in this episode, Dawn and Ken will be asking each other questions that listeners have directed their way. The show turned out to be a lot of fun and the chairman of the double-secret selection committee who chooses all the guests who appear on STEM-talk promises not to wait three years before getting around to do another Ask Me Anything episode.

Show notes: [00:02:31] Dawn asks about Ken’s time growing up in Guantanamo while his father was stationed there in the Navy. [00:02:59] Ken points out that Dawn spent part of her time growing up on a farm and asks her what that was like. [00:04:46] Dawn asks Ken about visiting Navy gyms when he was a kid. Ken then talks about how much he enjoyed those times, but that gyms have now become fitness centers. [00:05:43] Ken talks about his pet peeves during his workouts. [00:06:40] A listener writes in to say that he tried a ketogenic diet, but was never able to get over the “keto-flu.” He asks Ken to discuss this phenomenon and whether the ketogenic diet may not be for everyone. [00:07:44] Dawn follows up on the previous question and asks Ken for his thoughts on what constitutes a good diet if someone finds that the ketogenic diet isn’t right for them. [00:08:30] A listener asks Dawn about the APOE genotype, which has been mentioned on STEM-Talk several times. The listener asks about Dawn’s research into the genotype and what that research uncovered in regards to its relation to brain health. [00:11:09] Ken responds to a question about his views on the effectiveness of the ketogenic diet for older and middle-aged individuals, and why he thinks the diet might be considered an anti-aging diet. [00:14:39] A listener asks Ken to explain what the Mediterranean diet actually is, given the nebulous nature of the term. The listener goes on to write that they have never seen any noticeable weight loss benefit for people on the Mediterranean diet, unlike what the listener has seen for people adhered to the ketogenic and Paleo diets. [00:17:16] Dawn asks Ken how he would define the ketogenic diet, given that the Mediterranean diet is so ill-defined. [00:19:58] A listener asks Dawn if she has ever attempted a vegetarian ketogenic diet, given that Dawn is a vegetarian. In answering the question, Dawn mentions that Dom D’Agostino's website lists resources for vegetarians and vegans who want to know more about ketogenic diets. [00:21:08] Dawn asks Ken for his thoughts on people on the ketogenic diet drastically limiting their protein intake. [00:22:57] Ken is asked about his thoughts on exogenous ketones, and he refers to a promising ketone ester developed by Oxford and NIH scientists. [00:24:34] Ken explains what sarcopenia is, and why people should want to avoid it. [00:26:17] Dawn mentions that Ken has said that the maintenance of skeletal muscle is contingent upon the balance between muscle protein synthesis and muscle breakdown. She goes on to ask what some of the factors are that drive this process in one direction or the other. [00:27:11] Ken discusses oxytocin, which is commonly thought of as the ‘trust’ or ‘bonding’ hormone and is important in reproduction.  Dawn asks about the role of oxytocin in the context of the age-related loss of muscle mass and function. [00:28:22] Ken describes what oxytocin is and does. [00:28:50] Dawn comments on how Ken mentioned that Conboy’s group at ...
