This is a superlative question-and-answer session where Dr. Dagostino answers questions collected from Tim Ferris’s listeners.
It’s not so much a pitch about why you _should_ do it (ketosis / the diet), but rather, it’s a deep discussion of all the details. What exactly is ketosis, how does it work, how do the systems in your body interact (at the various levels of organ, glands, hormones, cells, biochemics, and molecules.) Dr. Dagostino is obviously very much in favor of ketosis, but there’s a ton of useful information here.
To test the relationship between exercise and ketosis I decided to examine my blood levels of glucose, B-OHB, and lactate immediately before and after three different types of workouts on three successive days. This interplay is complex and no one knows “everything” about it, including the world’s experts (which I am not pretending to be). I’m going to try to balance a fine line in this post – I want to be rigorous enough to explore the ideas with substance but not too detailed to put you to sleep. I hope I am able to balance these forces adequately.

The more I read about the human body, the more fascinated I become. One of the big dietary changes I started long ago was to just “try to eat fewer refined carbohydrates.” Less cookies, breakfast cereal, that sort of thing. And then I spun off into intermittent fasting and ketosis and on and on.
But this guy, he’s gone way WAY farther down the rabbit hole. This article is a superlative dissection of ketosis, fuels (carbohydrate, protein, fat), wattage, workouts and … well, the best part is after all of it, there’s no strong conclusion. It’s just this wonderful exploration of how one person’s body performed under a bunch of circumstances.
Anyway. File this one under: Human body = amazing.
