Ketosis is just as natural as menstruation. You do not HAVE to be eating a lc woe to experience ketosis. All you have to do is burn fat. Ketones are the harmless by-products of burning unwanted fat. Athletes experience ketosis on a regular basis and they probably don't even realize it because it is not acknowledged. California's new governor has, no doubt, spent many hours in ketosis. I have total recall of having that metallic taste in my mouth many times...long before doing Atkins. I now assume that I was in ketosis at that time. Therefore, ketosis is a safe body process that, probably, everyone has experienced at some point in their lives.
