In this interview segment, Mihail Pautov asks an expert about the safety of extended water-only fasting, such as 30‑day fasts. The expert acknowledges that occasional short fasts (one or two days per month) are likely harmless, but warns that longer fasts may damage the gut microbiome and gut lining, citing animal studies where microbes consume the host’s gut tissue when deprived of food. The expert admits the exact harmful threshold is unknown and states there is no solid evidence supporting regular long‑term fasting as beneficial. Instead, they recommend more sustainable practices like time‑restricted eating, which can be practiced most days without the risks associated with prolonged fasting.

Even we have people that are going to 30-day fasting, like 30 days only drinking water. What do you think about that? Can that harm your microbiome?
Yeah, I think fasting for a day or two a month is probably not harmful.
A day or two in a month. Okay.
I, you know, but if you go beyond that, you know, there are potential dangers. It may not be easy for people to do. And there's some evidence from animal studies that your microbes start to— your gut lining starts to deteriorate because the gut microbes have actually got nothing to eat except your gut lining.
Yes.
So you start to eat yourself. And so there's probably a point at which, you know, healthy becomes unhealthy.
Yeah.
We don't know what that is yet. So I don't advise people to do more than the occasional fast, which some people find psychologically important. But there's no good evidence that, you know, regular long-term fasting is good for you. Um, so I think people should do something more modest like this time-restricted eating, it's called, uh, which is very easy to carry on most days of the week. You don't have to do it every day of the week.
Yeah.
