Who are you to define what is the correct way to enjoy food? You'll also notice there are many women. You might be attributing comments to people who eat lightly because they don't have the stomach space for it.  On top of that, there are men who prefer to be lean, or even minimalist in there food. Just because they don't like greasy or dense things doesn't mean they aren't enjoying what they do eat.  There's more than one way to look good as well. Mirin' is nice and all, but some guys have developed their own look. And women find them attractive as well.
