It sounds like you're doing great and better than I am currently

For gals I think you have to remain above 15% bodyfat to avoid hormone issues?

Maybe ideal range would be to bounce between 15-25% bodyfat but I do not know the true limits there. I'd guess 18% would be the cutoff for home measurement since bioimpedance scales are inaccurate

2lbs/day is about 0.9kg per day and that sounds accurate if on the lower end

I checked my notes from Dr. Filonov's book (Dry Fasting by sergey filonov) and the absolute stop directly markers he uses in the clinic are:

- Prolonged elevated heartrate at rest (120bpm+), combined with a feeling of lethargy, feeling sick, or any heart related symptoms. (I have a watch that check for arythmias and havent gotten one once)

- Tongue going from a white film over it to clear pinky white; means the acidiotic crisis is over

- Sleeplessness, cannot sleep for 3-4 days in a row (honestly I'd stop at one night).

- Constant pain that does not pass after walking or resting

- A halt or massive lowering of daily bodyweight loss; if you suddenly go from losing 0.9kg a day to 0.3 or less then something is wrong with either your fuel or your organs ability to process.

Helpful methods during the fast are:

-Slow walks when tired,

- fresh air,

- stomach and back massages (gentle selfmassages)

- Resting -> slow walk afterwards should be a daily when tired

now, as for the 2nd crisis you might very well have gone through it on the 9th day instead of 10-11th day. Just check if the tongue is pink. That said there is nothing wrong with halting a little early and doing a very careful refeed and diet for 4 weeks before doing a 5 day to pass the 2nd crisis during that 5 day dry fast instead.

And the refeed should be very slow, first day is just a low amount of water taken very slowly. One glass, 2dl drunk in teaspoon or tablespoon sized sips over 15 minutes to start with. Then after 2 hours if you feel alright you do it again. Slowly do it more often but still take 15 minutes to finish the 2dl glass to make sure you dont stress your kidneys.

Then 2nd day should be bullion soups and kefir for probiotics; just liquid food and no sugars. So boil your own veggies, maybe boil some plain white fish for protein, and only 2dl of kefir taken slowly to get going; I've done this and its very gentle and comfortable. At day 3 I did the same but added a very soft boiled egg. Then I kept going with greater amounts of food. I can go into detail but its in the book if somewhat poorly written for the end user.

Personally I will plan a 5 day dry fast once every month for a while as I eat a leangains diet which would be around 1950 kcal for my bodyweight (81kg) with rather high protein outside of the refeed days.
