Keto Clarity – Book Review

BJJ Caveman Keto Clarity Book Review DISCLOSURE: I’ve said this a few times before, but I’ll say it again.  While I don’t know him personally, I like Jimmy Moore.  He’s been a supporter of my site and has personally answered every single tweet and e-mail I’ve sent him.  He was also the inspiration behind my ketogenic n=1 experiments.  I pretty much just copied his n=1 nutritional ketosis experiment when I first read about it. If you’ve been following me at all you’ll know that I’m a big fan of ketogenic diets and have experimented with the different variations:

After all of these experiments, I can say confidently that I’ve learned a lot more about everything ketogenic.… Read More

Even Ben Greenfield Has Thyroid Problems While In 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.… Read More

Cyclic Ketogenic Diet and Thyroid Hormone

Thyroid GlandCyclic Ketogenic Diet and Thyroid Hormone

Brief Summary:

Recently I completed a 10 week experiment doing a variation of a cyclic ketogenic diet called the Carb Nite Solution, which basically entails eating strict low carb (less than 30 gm per day) with one 6-8 hr window of massive carb loading per week.  At the end of this experiment, before going on a trip to Italy, I had a series of fasting labs drawn.

So far we’ve looked at my:
