I have read them. I’m an academic librarian and was a medical/science librarian for years before entering administration. Know a bit about this in addition to being a top 1% masters athlete at 54 and married to a world ranked powerlifter/bodybuilder. You learn a bit about diet after 40 years as an athlete. I dont think I've ever had this debate with anyone fitter or with better health markers than me. I probably eat a half pound of meat plus full-fat dairy and eggs every day by design but rarely sugar and only moderate carbs solely for endurance exercise needs.
