With all this junk food talk I'm going to chime in on some healthy foods I have found as a revelation. Pearl barley has a really odd texture/bite to it, and may take getting used to (it chews a little like gristle) but possesses magical appetite suppressant properties, without feeling too full or heavy. I have no idea if it expands or has uber chemicals, but I find I don't feel hungry after eating it. The other (personal) super food is green curry paste (no coconut milk/cream). It's quite intense and has a punch undiluted, but 1/2 a teaspoon to a teaspoon is enough to have me craving just water/green tea. (Curry powder too is quite magical.) I highly suggest you guys explore the potent and hot spices. A tiny amount of Tabasco and rice wine vinegar makes any vegetable sing. Oats. Glorious. Lentils. Anything in miso soup. Adzuki beans. Expanding any meal with cooked celery.
