It’s that time again for another Ask Me Anything episode. And we must say, listeners sent us a wealth of excellent questions for this round of Ask Me Anything. In today’s podcast, Ken and Dawn answer questions that range from blood-flow restriction to swimming induced pulmonary edema to intermittent fasting to methylene blue to low-carb diets, and much, much more. If you have questions you want to send to Ken and Dawn for an Ask Me Anything episode, email your question to STEM-Talk Producer Randy Hammer at firstname.lastname@example.org. Show notes: [00:02:24] In light of Ken’s former experience in wrestling, a listener asks about wrestlers who perform neck bridges to strengthen their neck. The listener wonders if Ken thinks neck exercises are important and, if so, what does he does in that regard. In his response, Ken mentions a neck-strengthening device, Iron Neck. [00:06:12] A listener asks Ken and Dawn about their morning routines and what scientific journals they read and if they could each give a few book recommendations. [00:08:16] A listener asks Dawn, in light of her accepting a position at the University of North Carolina, if she will continue working with IHMC and co-hosting STEM-Talk. [00:09:13] A listener asks if and how Dawn sees crossover between the research on humans in extreme environments that she did at IHMC, and the clinically oriented work she is doing now. [00:10:37] A listener mentions that they have recently started using blood-flow restriction training in their workouts thanks to STEM-Talk and have enjoyed the experience. The listener goes on to mention, however, that they are noticing they feel light headed when going for a run after a blood-flow restriction resistance workout. The listener asks Ken if he has any knowledge of this phenomenon, or other side effects of blood flow restriction exercise. [00:12:56] A listener mentions that they have just finished reading Denise Minger’s “Death by Food Pyramid” which explains that no nutrition-oriented classes are required for a Harvard medical degree, which is also true of about 70% of medical schools in the nation. The listener goes on to mention, from their own experience, that people are often told to consult their doctor when thinking about the potential benefits of new diets. Doctors and even nutritionists, however, generally prescribe the Mediterranean diet and do not seem to know much about low-carb diets. The listener asks Ken who one should consult when wanting to start a ketogenic diet. In his response, Ken mentions several resources, including the websites Virta Health and Diet Doctor; and the books “The Art and Science of Low Carbohydrate Living” as well as “The Art and Science of Low Carbohydrate Performance.” [00:15:22] A listener, who is a triathlete, asks Dawn for advice about performance in extreme environments, particularly in regards to swimming induced pulmonary edema. They also go on to ask about Dawn’s thoughts on Sildenafil, also known as Viagra. In her response, Dawn mentions a paper by Dr. Richard Moon of Duke University, “Swimming-Induced Pulmonary Edema: Pathophysiology and Risk Reduction with Sildenafil.” [00:20:08] A listener asks Ken a question about an article they read about a study out of the University of Glasgow that was published in Nature Scientific Reports. The listener highlights a quote from the press release announcing the publication of the article: “There is no magic diet, or magic food, for weight control. Instead, people have to find the best way to eat fewer calories. Low-carb diets have had a lot of hype from media and celebrities, but they are no better than high-carb diets. Their evidence is generally poor, and our earlier research found low-carb diets are associated with some vitamin deficiencies, with more diabetes, not less. We can't stop people cutting carbohydrate, and it may suit some people at least in the short-term, but there should be a health warning.
