In the span of a week or so, Ben Greenfield appeared on Dave Asprey’s Bulletproof Exec podcast AND John Kiefer’s Body IO FM podcast where he discusses his experience training for and performing in Iron Man races while in full nutritional ketosis.
He describes one of the main side effects that he encountered being severe hypothyroidism… manifesting as severe sensitivity to cold, poor libido, and poor overall energy.
The way they treated this was to eat a lot of liver, dessicated thyroid, and sweetbreads which seemed to fix things for him.
I’ve actually tried liver before… and it almost made me vomit. I just couldn’t get over the texture of it. I’ve also tried sweetbread before… with the same result.
Not sure how much of this is mental and how much is due to the actual taste/texture…. but I’m just not quite at the point where I’m ready to go to town on organ meats (here’s one thing my inner fat kid and I can agree on).
Given my aversion to these measures, it looks like I’ll have to continue to explore other methods to address my thyroid issues. If you’re interested, you can read more about these issues here:

In the end, Ben Greenfield concludes that trying to stay in ketosis all the time, despite the performance benefits, is just too difficult and inconvenient. He likes being able to eat carbs one in a while and doesn’t like having to eat so many organ meats so often…
