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.
In a word, yes. But, technically this is the wrong question. The correct question is probably closer to, “What is the impact of the calories I consume on my body’s ability to store fat versus burn fat?”
Conventional wisdom, perhaps better referred to as Current Dogma, says that you gain weight because you eat more than you expend. This is almost true! To be 100% true, it would read: when you gain weight, it is the case that you have necessarily eaten more than you expended. Do you see the difference? It’s subtle but very important — arguably more important than any other sentence I will write. The first statement says over-eating caused you to get fat. The second one says if you got fat, you overate, but the possibility remains that another factor led to you to overeat.

All of the success in the last (roughly) five years boils down to the following strategy. Notice that “excercise” does NOT appear…
1) realize I would like to improve my health
2) read something (anything) about health, diet, metabolism… anything that piques my interest. But it has to be something I think is TRUE. No crazy “fad” stuff. Something sane like, “yogurt seems to be good for me to eat.”
3) reduce friction to lead to that change. NOT, “force change by making rules.” I want to eat more yogurt? …make sure it’s on the grocery list so it ENDS UP IN THE HOUSE. I want to stop eating Doritos? EAT LUNCH BEFORE GOING TO MARKET, DO NOT BUY DORITOS.
There is no step 4. Everything else happens automatically. There is NO CURE for curiosity. Each thing I read and adjust leads to more, interesting questions. And along the way, more activity just happens automatically as my health improves.
Yes yes yes. I’m personally interested in movement and Art du Déplacement, etc. So I’m also doing this process in that realm. Forget about that. The success with my health, came all from my diet.
