I did Bulletproof Coffee the other day to take a full 16 hr fast to a quasi 24hr fast and also as a way of transitioning from 16 hr daily fasts to a day to day 23 hr fast.
All I can say is it was an amazing experience! I normally feel a bit sluggish shifting gears into and out of ketosis while fasting. This experience was like the clouds parting and the sky clearing in my brain. I accomplished all my weekend chores around the house and exercised hard while in ketosis. I have never before this cared to exercise hard in fasting ketosis.
I am concerned that the saturated fats may be harmful, but how can something that feels so good be so bad?
I am trying to convince myself that saturated fats are only bad when combined with carbs and that if you burn them up before leaving ketosis it can't hurt you.
Any thoughts? Any Science? Avacado-Olive Oil instead of butter and coconut oil?
It was an amazing experience!
