  • In this episode we discuss:

    Why uncoupling is harmful in certain contexts and how PUFA cause constant, low-level uncoupling

    The involvement of uncoupling, mitochondrial biogenesis, autophagy, heat shock proteins, and hypoxia-inducible factors in the stress response

    How stress prevents our mitochondria from effectively producing energy

    How chronic stress causes insulin resistance, high blood pressure, weight gain, depression, and cardiovascular disease

    How sugar and fat cravings result from stress and why listening to them is beneficial

    How adaptations to stress get passed on through generations

  • In this episode we discuss:

    Whether cod liver oil is an ideal source of vitamin A/retinol

    Whether we should be concerned about the omega-3 content of cod liver oil (CLO)

    The idea that we want our fat cells to be insulin resistant to lose fat

    Whether keeping insulin low is the key to fat loss

    What hormones regulate fat loss

    Timestamps:

    2:54 – what we think about cod liver oil as a vitamin A source

    9:50 – why someone may benefit from cod liver oil, and why it likely isn’t a result of the retinol
