I've gotten sick twice, but my immune system took care of that rather fast. I barely experienced any symptoms and made recoveries within a day or two, something that never happened before
Eating 2 meals a day was bad for me because I'd feel a lot groggier eating over a 1000 calories/meal to meet daily requirements
I speculate that maybe I eat less now than the daily requirements on occasion. I have a large amount of fuel stored, which seems to be easily accessible these days (to judge from the rate at which it is being consumed, anyhow).
Perhaps when my weight has normalized I'll get hungry more often.
