I could never be that thin and not be starving all the time. I could never eat that few of calories and not feel like death either. This is no answer to you, though. I'm sure you would never tolerate being as large as I am. I have decided big (-ish, I know I'm not FAT), strong and healthy feels better to me than skinny even though skinny is more acceptable these days.
