Dangerously based, but it wasn't just the Bronze Age goatfuckers. Fasting was recorded in Europe about the time Christianity came, and Chinese and Japanese cultures did it as well. In fact, most armies, even in the modern day, eat meals every two days when they're on campaign. Sure, extreme example but war fighting burns massive amounts of calories and if they can do OMAD and make it through a day's march it leads me to believe it's not as dangerous as we've been told it is for years. Maybe it was superstitious bullshit, but considering starving peasants in the Dark Ages could fast for a week and not keel over dead until the end of their life expectancy I'm sure my overfed ass will be fine.
Autophagy pulls dead cells from the liver to help it work more efficiently, so I'd say I'm doing okay. I'm not totally convinced on the anti-aging aspect, but lowering my risk of cancer and Parkinson's disease sounded like a good deal.
How dare you, I never listened to a desperate middle-aged woman before in my life! My mother can attest to that! Besides, I do constantly have something moving through: water, tea, or snake juice (need to keep up the salt).
Oh, I believe you. But it's cheaper not to. This is an economic decision as well: price of food is really high, so I buy less food. Eggs are even getting ridiculous! Plus it's actually really convenient. I don't have to worry about what I'm going to eat at work or having to get processed crap at a drive-thru if I'm too busy to cook one day and I'm out of leftovers and canned tuna. I'll probably go back to eating one meal a day after it's complete/ after I fail, I'll see how I feel. Once I hit my goal I'll count calories and eat below maintenance again. I don't think fasting's a lifestyle unlike what those autists on /fit/ would have you believe, it's an extreme temporary diet to produce an extreme result, like you said.
