Given a choice, I'd live to eat. Instead I'm eating to live these days. So I try to cut out 'simple' carbs, reserve them for Feast Days and ban them otherwise. Oddly, don't miss 'em much after a while of 'weighing choices'. Medium protein/higher 'good' fat/'good' carbs watching the glycemic load is a surprisingly good diet for diabetics (and suggested by various diabetic support groups if not the ADA) So I think 'mediterrannean' or South Beach diets.
Much as I like bread I eat a lot more beans/legumes than bread these days and try to keep pasta both whole grain and rare. I try to sneak in some variety w/whole grains like wild rice, kasha, barley or wheat berries as 'flavoring' agents in a pilaf (and I use low-glycemic rice for my own purposes. I also highly recommend salsas - including fruit salsa - and chutney, relishes, etc...a few bites of very flavorful food like corn relish or mango salsa can make a bland piece of fish a lot more lively. Buy a few different bottles of good vinegar - balsamic, red wine, seasoned rice vinegars offer a lot of 'zing' for no calories/carb considerations. Beware of a lot of condiments, the sodium in mustard and carbs in ketchup can throw me 'off track' if I don't pay attention.
I eat a lot of things that are tasty because they have monounsaturated fats in 'em. Olives, olive oil, sesame oil, avocado - these replace 'baked snack foods' for me.
I have one more rule - if my Grandma would recognize it as food in 1950, I'll consider eating it. That rules out a heckuva lot of packaged foods.
