I've been using intermittent fasting for the last week (One 24 hour fast in addition to a 12 hour fast daily) and have experienced dramatically increased mood, at times I'm euphoric. I no longer have blood sugar drops after a few hours like I used to have, and how I see everyone in my family get. My ancestors diet have undoubtedly been a very fat and protein-rich diet, consisting of wild game, seals, etc. and very little carb,as I am Scandinavian, so it does make sense for me to try to replicate a high-fat low-carb diet.
While my expectation were somewhat high, I did not expect this. I'm spending all that laughing and smiling and truly feel good with myself and while interacting with others. I'm never abandoning this diet.
Anyway, is it the fasting, the ketosis or a combination of the two that's causing the mood elevation? I would really appreciate a thorough scientific explanation.
