In the other thread you mentioned strict "no flavored anything". Can you elaborate why not?
In my case I tend to feel less hungry after drinking lots of flavored water (e.g., lemon juice or flavored electrolyte powder [1]), but I haven't yet done long fasting. I want to try soon.
Also, have you noticed any cognitive decline when you were fasting for weeks? Difficulty concentrating, memory loss, lightheadedness, mood, ability to interact with people?
Some unflavored sweeteners have been shown to produce mild insulin responses. For me it was more of a psychological thing, especially on a fast that long.
And no, no cognitive decline whatsoever. If anything I had more energy. Also, I was supplementing electrolytes, and I ended my fast at like 25% bodyfat though, so keep that in mind.
