How does fiber affect appetite?

In a 2009 study, researchers in Toronto fed two groups of people breakfast. The first group got a low-fiber breakfast cereal with 1 percent milk. The second group was given a high-fiber variety (which contained 28.5 grams of fiber per serving), again with 1 percent milk. Three hours after that meal, the researchers gave both groups pizza, and told them to eat until they felt comfortably full. Compared to the group who’d eaten the low-fiber cereal at breakfast, those who’d eaten the high-fiber cereal consumed fewer calories from breakfast and lunch combined. They also said they felt more satisfied.
