dcc0455 - how are you determining whether you are "in" or "out" of ketosis? I find that because I'm fat adapted and in ketosis most of the time, it takes more to take me "out" of ketosis, and I get back "in" much faster, within a day in most cases unless I go completely off the LCHF reservation. I'm using a blood meter to measure this, so it's fairly accurate. Depending on how you're measuring ketones, you may be there or get back in more quickly than you realize.
