So, "Wait, could I be starving myself?" isn't a question I often ask. I have access to food, I am extremely unlikely to ever go hungry. Even should I end up homeless and broke there would still be resources available to me.
Starvation isn't really something that needs to come up in my thinking because I am lucky enough to be in a situation where it's extremely unlikely to ever be an issue. Unless, you know, I stop eating for no good reason.
I noticed that I was losing weight, actually getting closer to where I wanted to be, in spite of putting in no effort in that direction and absolutely no good reason for it to be happening.
I don't want to give a full accounting of every action in my life, but the only possible cause was reduced caloric intake. Didn't remember the last time I had a meal worth speaking of.
So I've put an effort into eating more. Made pasta with meat and tomato sauce, for example.
I still have lack of sleep bringing me down, trying to catch up on that, but damn do I have more energy today.
