I'm fortunate in a way since I'm really sensitive to certain carbohydrates in food. I simply cannot eat sucrose at all without feeling ill and hungry within minutes. I may be borderline hypoglycemic or something since my insulin response is really heavy-handed. Anyway, I just cut sucrose out completely and I always feel great. I can eat sugars from fruit, honey, agave, etc. no problem, but sucrose is completely different for me. High quality breads don't affect me negatively, so I eat a fair amount of them, but the best food in terms of satiety per gram or whatever is pizza every time. It's not all pizza, as some places must have sugary sauce or something, but there's this one place down the street (Pizza Roma in Portland, OR) where I can get a slice of cheese pizza and not be hungry at all for 5 hours, sometimes more.

My view of eating is completely different from most of the people I know. I view eating as a horrible nuisance that interrupts more important activities, so I'm always trying to get more "satiety time" out of everything I eat so I obviously don't eat much in the way of low-quality food.

Incidentally, I've lost 21-22 pounds since I cut sugar out of my diet. I was always really active, but my weight would gradually increase over time since I would eat a meal and then have something with sugar in it and then have to eat more to get my blood sugar back up after the insulin caused it to plummet. I wasn't obese or anything at 5'10" 180, but I'm definitely much less flabby these days. At this rate, I'll be totally ripped in a few months without doing much avoiding anything but sugar and with a normal amount of activity. I also hardly ever drink alcohol, which I think lowers the total number of calories I ingest while not interrupting the liver's ability to metabolize fats.
