Never thought of that, but it seems to be a good rule of thumb. Some days I am just more hungry no matter what I eat, so I may need to take a closer look at what might cause that. Dairy, like cream or cheese is hard to give up entirely

I think the biggest culprit is lack of quality protein. Beef Jerky, even though fairly low fat, seems to sustain very well. It's also spicy and quite salty too, and it requires a lot to chew. Bacon, of course, is another.
