You lose as much as you need to. Many people who struggle to gain weight, actually do post-fast.

I meant, how much weight do you, ~aviv, personally lose on an 8-10 day dry fast?

Also, still wondering if you're in a dry or humid climate. And come to think of it, whether you're in a hot or mild climate.

Because I know of people who've been drinking water, but still reached a point of dehydration requiring medical attention, in hot or dry environments after moderate-to-extreme exertion. So my hunch would be that an 8-10 day "dry fast" might require minimizing activity in a cool, humid place.

The breezy vagueness of ~aviv's responses makes me somewhat skeptical of the reliability of his self-reports.

It's easy to just continue believing in your own path. I could not care less if a random HN user finds my answers vague. My comments here get flagged the majority of the time so I put very little effort into the responses nowadays. And to answer your question, I live in very dry climate.

Thanks for the climate moisture answer. Still wondering, is it hot or mild? (Do you engage in any activity that requires sweating during a dry fast, or do you minimize physical activity?)

And also still wondering: how much weight do you personally lose on each of the 8-10 day dry fasts you practice 3-4 times a year? (I find it strange such a simple question hasn't been answered.)

Of course I minimize my physical activity during dry fasts.

Hot. Arizona hot.

I don't track the weight anymore, about a pound a day, maybe a bit more. Early on it was nearly 2 pounds a day. Regain 75% of it on the scale rather quickly because I eat mostly fruits due to their water content. The weight loss is not what I'm after, as I said before, any weight loss during a dry fast is normal and expected. Those who need to put on weight generally do shortly after a fast is completed
