I know it's a far cry from the usual gamer staples of "crisps and candy", but my food of choice is fish and veggies. It's all I really ever eat, though once in a while I indulge in sweets (usually liquorice).
For fish I rotate between salmon, tilapia, herring, carp, catfish and rockfish. Veggies are some combination of spinach, kale, jie lan, baicai, mustard greens, turnip greens, sprouts, green onions, white onions, okra, peas and carrots. Sometimes I add mushrooms and/or prawns to the mix too and prepare everything in a variety of ways. I avoid pasta, rice, breads and other high carb, starchy foods; but I sometimes use crumbs to make breaded mushrooms/okra or pan-fried catfish. I pair with a glass of Cabernet Sauvignon or Pinot Grigio (I prefer the former even though fish/seafood is typically paired with white wines).
For most of the day I get by on soda (Pellegrino, Perrier or generic shop brand) and coffee (freshly ground French Roast or Dark Colombian). I haven't had much time to game, but when I do it's probably fuelled by those.
