Dry Fasting Club Forums

I have experience with water fasting for about a year and dry fasting for about six monthes.
Also, I've been on a low-carb diet for a year now and have been doing omad for half a year.
2-3 months ago, I started experimenting with extended dry fasting (2-3 days).
I have completed two 2.5-day and one 3-day dry fast.
the last one was 2.5 days.
I already have experience with food reintroduction, so refeed went well. after extended dry fasting, I always doing water fast for at least a day. This time, water fast was 1.5 days. I also included a fairly large amount of magnesium glycinate and a standard dose of zinc.
the only thing that bothers me on the 3rd day after the 2-day adaptation to food is that the tastes are still too pronounced.
especially the spicy ones. I have never experienced noticeable deviations in taste perception after fasting or changing my diet.
I used to be able to safely eat even very spicy things (obviously not in the first days after refeed ended), but now even allspice sets me on fire.
also interesting, the food tastes began to remind me of what it was like when I was about 10 yo. Don't know how to describe it more precisely.. the same foods have acquired a different taste for me over time. now everything seems to have returned to more than 10 years ago.
What could be the reason for this?

Rejuvenation of the senses, including brain tissue where taste is processed, and focused on autophagy and stem cell regeneration. It is similar to psilocybin, which significantly alters neural processing, making the brain more sensitive in some ways while changing how different regions communicate. It achieves this primarily through increased neuroplasticity and changes in functional connectivity. Dry fasting has significant quick impact on the brain, so we can expect neurogenesis too. I also believe that dry fasting hyperpolarizes cells. One older study on rats found that fasting for 24-72 hours resulted in an electrical hyperpolarization of intestinal cells, which was linked to adaptive responses for nutrient transport.

Hmm, I also thought about it initially, but it seemed to me that it could not be so noticable.
after 7 days, everything returned to normal. although my love for spicy food has clearly decreased.
after writing the original post, I ate fairly bland food for 3 days until I stabilized and also stopped taking zinc and took a break from lamenaria(as iodine can affect taste too, afaik) for a couple of days.
Don't know what exactly helped in the end, but sometimes, if taken on an empty stomach, zinc gives me quite strange side effects in terms of taste perception, especially after resuming zinc intake after breaks. I don't know why, it's never looked like an overdose in any form, and the dose is too small for it.
There may well have been a combination of factors.

I remember my grandpa telling me how he after a routine surgery with anesthesia, woke up with extremely amplified sweet tastes for several days after.
Like sugar turned into sucralose type of sickeningly toxic sweet.
Doctors insisted it was something that could happen after the anesthesia. No idea why. The nervous system is wicked weird.

This makes sense. Also reinforces the theme for me that my fast did not make a dent in my brain stuff yet. I've had no sensorial changes at all (and I'm a very sensory person so I would notice!) and no puncture in my brain fog. I had seen the psilocybin studies a bit but appreciate this dot connection.
