(2:30) What she found out was a symptom of metabolic problems. Dr. Shanahan was one of the early voices who emphasized the toxicity of seed oils. (6:00) She explains how she started paying attention to seed oils. Her background in biochemical engineering transitioned to medical school; however, her personal medical issues led her to a deep dive into health. Her book “Dark Calories” is available in Vinnie’s Book Club . She explains the meaning behind the name. (13:00) Metabolic disease is rampant. Being “hangry” is a sign of insulin resistance, which is a stage of metabolic disease. New standards of testing need to happen; she’s a big believer in using the HOMA-IR testing. They discuss oxidative stress and seed oils and how they are included in many things. (20:00) She defines what she has named as “The Hateful 8.” It’s a similar effect of oxidation as cigarette smoking. Vinnie asks her about her list called the “Delightful Dozen.” (27:00) She hopes to get more doctors on board in expanding the message regarding various oils and the effects of oxidative stress. (35:00) Free radical particles are caused by oxidative stress; vegetable oils are “oxidative stress in a bottle.” (42:30) Empty calories from processed foods and sugars can cause them too. She also challenges the use of protein powders. (46:00) Respecting Nature and how it works is important; trying to “outsmart” nature is a dead-end game.

(1:10:00) Vinnie asks Cate’s take on GLP-1s. (1:14:00) She is against them for many reasons; the first one is that those drugs are working against Nature.
