Most guys (me included) are thrilled to find a meat-eating, thin-looking GF - my little redhead is very supportive of my eating needs and I am crazy about her - when the dinner comes with a potato, she very efficiently makes it disappear from my plate.

Most guys also can't relate to women's obsession w/ food - dieting and losing are easier for men, and we are judged less by our weight and more by our wallets.

If it is just your second date, don't sweat it - your obsessions (if you let them show) won't become annoying to him for at least a couple of months or so. The more he enjoys you, the less he will care about the annoying parts.
