Episode 28 – Amber O’Hearn says meat heals & birds fly

 

Show notes:

  • Amber’s guest post Ketogenic diet and Vitamin C: the 101
  • Amber’s website http://www.ketotic.org/
  • Amber’s Ketofest 2017 video presentation
    • In her presentation Amber explains that that animal sourced foods (AFS) score high in terms of diet quality, defined as the addition of 3 differently weighted parameters in the following formula ⇒
      • structural plant parts (e.g. indigestible cellulose)
      • [weighting x2] Plant reproductive parts (e.g. starchy bulbs)
      • [weighting x3.5] Animal prey (e.g. red meat)
  • “[…] If our teeth aren’t well adapted to a particular food, it’s unlikely the rest of our digestive tract is. […] we did not evolve to eat copious quantities of starchy, sugary foods.” – Daniel Lieberman (2013), Human Evolutionary Biologist, Harvard University
    • Amber mentions how the state of our teeth can serve as a canary in the coal mine with regards to our cardiovascular risk, for example [Watanabe & Cho 2014]
  • Species snowflakes, not individual snowflakes (even though we do vary in our individual tolerance to particular compounds)
    • Amber says “We are one species and we’re much more likely to have variation in the way that we break down rather than in the way we are healthy”
  • Amber mentions a fascinating paper about the physiology of birds to make the point that the interaction of dietary factors can change our respective dietary needs ⇒ It takes guts and more to eat fruit: Lessons from avian nutritional ecology (2001)
  • We talk about PROTEIN and PSMF (Protein Sparing Modified Fast). Ted Naiman tweetedI have diabetics who stall out on lowering A1c by eating a ton of bacon. Ask a diabetic to eat a high fat meal at dinner and check glucose the next morning, then do the same thing with isocaloric high protein lower fat
  • Dr.Rakesh Patel said maybe “Worsening peripheral IR ?” could explain this progress stall
    • I asked him he think this would hold true in a rib-eye only diet (to keep things simple) and Dr.Patel saidprobably not for the majority as along as quantity is controlled, but possibly so for certain susceptible individuals
  • Amber raises an interesting question she talked about with Richard Morris ⇒ is there a limit of fatty acid efflux from adipocytes that can be surpassed when fasting or going very low-carb that can account for feeling tired?
  • I ask Amber about her views on Spreadbury 2017 ⇒ “some very high carbohydrate diets have also been shown to be compatible with population-wide optimal metabolic health in non-cereal agrarian populations” citing Lindeberg’s papers and Johnson
  • Amber mentions biogenic amines, a topic both of us learned about from Dr.Ede
  • I mention having a  IgE anaphylactic type allergy to shellfish (e.g. crustaceans, such crab, shrimp & mussels) since I’m about 11-years old. A few months ago however, I ate mussels at a restaurant by mistake but suffered no reaction whatsoever! This is apparently quite rare (assuming I am in fact no longer allergic)
  • Amber mentions having had Bipolar Disorder Type 2 and I ask her if she noticed diet affecting her mental health ⇒ she says that going very low-carb helped a lot but going carnivorous was still a major improvement
  • I mention rodent research in rodent models of schizophrenia showing that aberrant transport of mitochondria along axons leading to energy failures in neurons. This is postulated to explain symptoms of schizophrenia [Devine et al. 2016]
  • Amber is writing a book!
  • Amber shocks parents on the playground at her children’s school saying she tries to eat a 60-70% fat diet. I love it…
