Boy, I feel full.

Tia Ghose explains how images of food effect our perception of how full we are,

The results show that there's more to hunger than the physical stomach rumblings.

"We store memories of what we think we've consumed and that somehow affects and regulates the hunger we've experienced between meals," Brunstrom said.

It also has implications for foods advertised as low-fat, Schoeller said. "If people are expecting that it's not going to be very satisfying and also that it's something they can eat without gaining weight, there is a tendency to eat more of it. And this study suggests that part of that might be related to our perception of how full we are."

Still, it's premature to hook a pump to your soup bowl in hopes of tricking yourself into losing weight, Schoeller said. "You don't know for sure if this translates from a single meal to a chronic effect of 12 weeks of eating smaller meals." That's because physical hunger cues may overpower visual cues once someone has tried to cut calories for a longer period of time, he said.
