I fast for long periods at 8-12% body fat and deal with cold hands/overall cold as well.
I’m trying something new, iodine.
After reading an “OLD” (circa 1990) diet book that basically said to eat a keto diet, even though they didn’t realize it, I came across a paragraph discussing a lack of iodine and how it could cause cold extremities, dry skin and a few other issues that I suffer from.
So, I went to the pantry and checked, the salt that we normally use, no iodine, the sea salt we use, no iodine, lite salt, no iodine… hmmmmmmm
Considering the fact that I’ve been doing IF and long term fasting (4-15 days at a time) for over a year, I could have “used up” any iodine stored in the body and am running a deficit over time.
So, I now take an iodine supplement each morning along with my keto aid. The winter is coming up, we’ll see how it works when the temps drop!
