Tamsin Lewis, MD draws on the possible connections linking ketosis and anorexia and how that may affect behavior and neurotransmitter changes from the voluntary starvation. We transition the conversation to fat adaptation, mitochondrial function and carb cycling for endurance athletes. Get the full show notes: http://highintensityhealth.com/202 Join our member community: http://highintensityhealth.com/insider Key Takeaways: 02:28 Dr. Lewis’ Experience with Anorexia: She was diagnosed with anorexia at age 11. Anorexia’s focus is the control of food, which preoccupies one from other things that are happening. Perhaps the biochemical and neurotransmitter changes that result from starvation, force ketosis and effect the brain. Dr. Lewis’ mother called it her “anorexic high”. The massive energy restriction from starvation forces the body to get energy wherever it can, including stress hormones. Dr. Lewis believes that there is a genetic component to anorexia. It is on the continuum of anxiety disorders. component to anorexia. It is on the continuum of anxiety disorders.

Today’s guest, athlete and muscle-health expert Gabrielle Lyon, DO, will add more substance and context to this narrative about muscle. Check out the show notes: http://highintensityhealth.com/201 Want coaching? Check out our Inner Circle: http://highintensityhealth.com/insider Gabrielle discusses how muscle is the body’s largest site for fatty acid oxidation (aka fat burning) and glucose disposal. (This is why bodybuilders can enjoy high-carb diets and still be lean.) Muscle is dubbed the organ of longevity for a reason—without it, you’re not burning much fat for fuel and are likely not aging well. This chat may help to clarify a few aspects about muscle, including: - Combating age-related muscle loss (aka anabolic resistance) Here are the key takeaways: 00:48 Muscle is the organ of longevity. The only way to keep muscle healthy is to lift weights. Check out the show notes: http://highintensityhealth.com/201 Want coaching?

Ketogenic diet advocate and scientist discusses why and how brown adipose tissue is healthy. Join our Insider Program: http://highintensityhealth.com/insider Until very recently, brown fat was dismissed as, ““….that stuff on the upper backs of babies that humans lose with age.” Now we know the methods through which adults can increase the quantity and activity of these protective fat cells. Dr. Ben Bikman shares his latest scientific findings in this field and the synergism between the ketogenic diet and brown adipose tissue activation. We also discuss the inverse relationship between insulin and ketone formation, which should add some clarity to the narrative around the use of exogenous ketone supplementation for fat loss. Here are a few key takeaways: 02:02 During PhD studies, he learned that insulin is the metabolic key. Now that he has his own lab, the relevance of insulin upon normal metabolic health is his area of study. 03:11 Insulin is needed to Grow Fat Cells. 03:35 Distortion of the Fat Cell 05:59 As we grow larger fat cells and we reach 150% of what is ideal for our bodies, we start making new fat cells. As someone loses weight, they will not reduce the number of fat cells. They shrink the size of their existing cells. 07:14 Triglycerides are Not Relevant to Insulin Resistance 09:34 Muscle is Our Biggest Glucose Sink 10:35 Insulin is a Factor in Inflammation 12:08 Exercise is Important, but Diet is Critical 13:45 Toxic Lipids Cause Mitochondrial Alterations 15:39 Brown Adipose Tissue and an Uncoupling Protein 18:39 When Brown Fat Cells are Exposed to Insulin, Their Metabolic Rate Will go Down by about Half. 19:38 When our White Fat is Exposed to Ketones, Our Fat Goes from Storing to Wasting. 20:34 The Evolutionary Benefit of Ketones Inducing Wasting: Perhaps the conversion of white fat into heat burning instigated by ketones was meant for heat production. Our bodies act protectively. Evolutionarily, ketogenic diets would be seasonal. 24:55 Cold Thermogenesis to Activate Brown Fat: Constant cold exposure, to the point where you are shivering, works to activate brown fat. Ice baths and genuine cold exposure does this as well. 27:31 You Can Alter Your Metabolic Rate 30:24 Benefits of Low Insulin 32:46 We Need Insulin: It is necessary for normal mitochondrial function. Eating a healthy low carb diet will give you enough insulin variability. We want to keep insulin normal. 25:16 Time Restricted Feeding and Fasting to Trigger Beiging 28:05 We are All Insulin Resistant First Thing in the Morning 39:01 The Effect of Protein and Carbs on Insulin: If you are insulin resistant, you will get a huge long lasting fat storage spike from eating something like a bagel, as opposed to the quick bump for someone who is insulin sensitive. 41:45 Speculation that Exogenous Ketones Turn to Fat when Insulin is high 46:34 Dr. Bikman’s Morning Routine 48:08 Dr. Bikman’s Favorite Exercise is the Deadlift 49:09 Dr. Bikman’s Desert Island Herb, Nutrient or Botanical: He would bring cow liver, which is packed with mitochondria. We do not adopt the mitochondria of the meat we eat, but we can get the building block components of the mitochondria. 51:06 Dr. Bikman’s Elevator Pitch: Stop emphasizing a high carbohydrate/low fat diet. 51:36 Don’t Worry about Gluconeogenesis Join our Insider Program: http://highintensityhealth.com/insider
