Not that often, but sometimes unconsciously. Most of my time at home is spent on my desk or introspecting on my bed, and as per the limited room in my old crummy apartment my bed was right next to a mirror - so I'm bound to have done various poses out of boredom.
I love meat, so I try to eat that when I can - but usually I eat noodles and other Asian food more often. Sometimes I have no meals or just have one or two meals a day.
