(Disclaimer: I am not a doctor)<p>It&#x27;s great that you&#x27;re seeing benefits, but I wanted to bring this to your attention (and anyone else doing long-term fasting) in case you hadn&#x27;t already heard of it: <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Refeeding_syndrome" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Refeeding_syndrome</a>. In particular, &quot;any individual who has had negligible nutrient intake for more than 5 consecutive days is at risk of refeeding syndrome&quot;.<p>I don&#x27;t know in practice _how_ big the risks are - I&#x27;ve been meaning to get an official medical opinion for some time - but I&#x27;ve started trying to take it into account for my fasts (usually two or three days) and plan accordingly (drinking rehydration salts while fasting, and breaking the fast slowly, with plenty of milk for phosphates).<p>Apologies if you already knew about this.
