This one was 48 hours. Much more challenging than 36, because the second night I got only two or three hours' real sleep; I dozed a couple more, but it wasn't near enough. My body clearly thought this was no time for sleeping: I should be out tracking an elk or gathering a yam. Maybe next time I'll cut my caffeine in half; that might help.
It will be interesting to see where my numbers rebound to, as I re-feed. In previous fasts they've bounced back surprisingly little. I give myself permission to eat the food I missed, the day after my fast -- i.e. if I want to double the portions on my next three meals, I can -- but so far I seem to want only one make-up meal, and then I'm back to my usual routine. I actually expected a lot more bounce-back in the numbers than I'm seeing. If it turns out that losing weight was as simple as fasting occasionally, I'm going to be pissed. All those elaborate meal plans and finicking about macros!
I'm joking (mostly). I had to learn how to eat way differently. I had to give up processed foods. I had to learn to plan. I had to learn to maintain a kitchen. I had to give up spontaneous eating, except on three or four special occasions per year. It wasn't going to work without that.
But still, compared to the misery of continuous calorie restriction, this is just absurdly easy. Sure, I get hungry from time to time, but I was hungrier -- way hungrier -- when I was fat. When I was fat I was ferociously hungry several times a day. I think people who have never had a disordered appetite do not have any conception of how desperate that hunger is. Compared to it a 48-hour fast is a walk in the park. Who cares? I get to eat day after tomorrow. It's not like I'm going to starve.
It's downright comical to see the graph of my weight drop like a stone, off the bottom of the chart, after so many years of grimly driving it downwards, pixel by pixel. 148.5. But we have still to see the bounce-back, and to see if cravings arise. So far, nada.
I finished the fast at 2:00 yesterday, which is more or less dinnertime in my current routine. I ate "breakfast," and then a couple hours later I ate "lunch," and I was done. Now I'm back to the usual.
