Well, I'm pretty much an omnivore, especially given how busy I've been lately and therefore how hard it's been to really keep track of what I eat. I tend to still stay on the relatively healthy side food-wise, though I seem to constantly have a shortage of vegetables in my house except in canned soup form. In fact, nowadays I consider a cheeseburger a good source of vegetables (because of the lettuce, tomato, and pickles), provided they're the good cheeseburgers at the good burger joints rather than most large fast food chains. Here in America it's very easy to find a good cheeseburger, and here in California it's very easy to find a healthy one. (And by healthy, I don't mean with avocado--though most sandwich shops in California do seem fond of putting avocado between their bread slices.)
One weird quirk of mine is that despite the fact that I'm NOT lactose intolerant (I better not be if I mentioned cheeseburgers), I prefer soymilk over regular milk. There's just something about cow's milk that just doesn't taste that good to me for some reason. Otherwise the only regular milk I ever drink is chocolate milk and the cream I put in my coffee (and tea occasionally, though I put soymilk in tea as well).
There was this one time several years ago that I was on the most restrictive diet I've ever been on, not to lose weight, but to cure some intestinal inflammation problem I had. Being on the diet meant no grains (not even rice), no fruit, no sugar, no dairy, no nuts, no soy, no vinegar, no coffee or tea, and no processed foods. It was a nightmare. I remember the second day I was on that diet and I had no food in stock that I could actually eat, and for a while I felt like I was going to collapse from hunger. It didn't help that I had very little body fat to live off of either. Fortunately though, it only lasted for about four weeks. Who knows, this diet might be good to lose weight with, even though I didn't really lose any weight from it. But then again, I'm already underweight.
