I usually don’t feel refreshed. When I fasted and felt so hyper- I felt exhausted while hyper and would have loved some sleep. But it has been years since I got an 8 hr night. I think the body actually does need 8 hours, even though we oftentimes get less.
Strange fasting experience
My first post is an answer to your question I came across on a search I was doing. The reason your system went a little loopy is probably because fasting depletes minerals and electrolytes. You were probably low on potassium and maybe the other ones too. Whenever you do a fast, always take electrolytes and minerals. Salt, potassium, calcium, magnesium and trace if you can.
I haven’t fasted for a while, but I have the same response as @Chantarella on both short (1-2 day) and longer (3-5) fasts. Unfortunately no amount of electrolyte tweaking has helped with sleep, though it definitely helps for how I feel during the day. Sometimes it’s great to sleep less- I get a lot done! - but it feels a bit like I’m running on pure cortisol and it doesn’t seem sustainable. I can do well with time restricted eating for long periods and really wish that I had great sleep while fasting like so many people do…
I’ve had the same type of “issue” and I do think that It should be a lack of minerals/electrolytes problem as John and others mentioned.
Apart from depression, anxiety and loneliness. Or all together
Lately, I’ve been trying to go for like 17, 18 hrs of daily fasting and I have experienced a couple of those episodes.
For instance, 4 hours of sleep would have kept me awake for like another 24-32 hrs, but then one week later, I was ending up in sleeping long full 8-9 hours and still waking up feeling tired. (I usually sleep 6 hrs, or I do from 2 to 4 hours now, and another 2 to 4 hours later.)
Anyway. I’ve been used with intermittent fasting, I can say my entire life, but ever since I’m trying to respect the hours, like nothing to eat between 20:00 and 14:00, I have noticed considerable changes at how my body responds now to let’s say, pimples, or rashes. I was used when I was having a pimple every now and then, to “stick” with me for a week or 2. Now it’s gone in 3 days maybe, or it’s not even appearing anymore.
Also. my immunity levels, my CD4 count levels doubled up in the past year, and I do feel better than I have ever felt.
OK. I can’t give credit only to fasting as there are certainly other things that contributed to my immunity and well-being as well.
I haven’t tried Keto yet. It’s all new to me, and I’m trying to understand the downsides first and what can I do about it.
I have kidney stones, and I do have a cousin with diabetes who’s also on an edge of having a kidney failure, which makes me question therefore, if this Keto thing is actually good for us or not, and in what measure.
