I remember when I was on a week-long kick of eating eggs -- I'd hard-boil three or four after school and eat them instead of tortilla chips in front of the TV. After a couple days, I realized that I smelled like egg. My skin smelled eggy.

So, yeah, you begin to smell like what you eat. Eat a lot of Korean food and you begin to smell a little kimchi-y (like my Korean fiancée).
