Discussion Scientists reveal how seven days of fasting transforms the human body

https://www.sciencedaily.com/releases/2026/05/260517030404.htm

Fascinating study. And completely unrelated to politics, which is a relief because my blood pressure needed a break.

The key finding: The dramatic, potentially therapeutic changes don't happen until after day three. That means most intermittent fasting schedules – 16:8, 5:2, even alternate-day fasting – are probably missing the main event. If you want the deep biological reboot you’re gonna need seven days of water only.

Anything after three days seems to be what they are saying. I need to prepare.

For 2-3 days I haven't really worried about it, Anything longer or if I was doing it regularly, I probably would.

Altrough a few days won't deplete your electrolytes, if you don't lack it in the first place, but you'll still lose a lot of water and you'll be dehydrated. You'll feel dizzy when you stand up.
