Last year I fasted for a week just to see if I could do it, I really wish I had before/after stats and bloodwork done. I don't think it's something I will do again.

A week! That is a significant fast. My max was 70 hours or so; I do not plan to do that again, either.

  Well I would say that it gets easier as you go, other than you feeling progressively weaker and weaker. You probably made it through the worst of the hunger and cravings at 70 hours

    At the 70 hour mark, I wasn't exactly hungry, but a bit irritable, cold and distracted. And yes, a little weaker. Pulling off any demanding work in that condition would be nigh impossible for me.

      Wow I start to pass out at around 2pm and I get a terrible migraine past that if I haven’t had breakfast. But I’m only 130lbs and 5’11” so I don’t have much storage and usually have hypotension. I wonder what would happen if I push it

It depends on your internal (fat) reserves. I'm 58kg 1m83 (BMI 17.32), so I wouldn't really try such a long period. But there are days I eat a lot, I build some glycogen reserves (easily available fat, made from glucose) due to my diet with much fruits, or other stuff like rice, honey, then the next days I can fast intermittently and use that glycogen. As a result I can't really gain weight, it always balance itself to that weight. I think people with more weight, have deeper fat, and it'll take longer to use it. I remember seeing an article that our ancestors possibly were hibernating. The more fat, the more time you can spend fasting, even on a dry fasting (fat holds water), but in that case it's important to limit physical exercise

  Glycogen is a polysaccharide, not fat. It is metabolized in a completely different way.
