Well written and basically coincides my experience. One comment is point #10 what breaks a fast - I would be more strict with what breaks a fast and also it depends on what your goal is. For a daily 18 hour - goal being weight loss/maintenance and protecting insulin sensitivity - I will sometimes have ghee or coconut oil (pure fat) in the morning or in between a meal - but strictly no carbs or protein. If I were doing a strict 3 day fast purely for autophagy I would not have any ghee or coconut oil. I would just be consuming water, electrolyte supplement, potassium and magnesium, sometimes a pinch of salt - zero calories. So carbs and protein will stimulate insulin but pure fats is different. If 1 gram of sugar is 4 calories then 50 calories is 12.5 grams of sugar. Ingesting 12.5 grams of sugar from what I read will disrupt autophagy and your fasted state by stimulating insulin - maybe more if you have any insulin resistance.
