When it comes to eating, we're very visual people. If food looks delicious, we're more likely to eat and enjoy it, and research shows that the more that's in front of us, the more we have an appetite for. Since we tend to eat whatever is on our plate, set yourself up for success by giving yourself an appropriate portion size. I find it's helpful to use small salad-sized plates instead of large dinner plates — when I see more food and less plate, I feel more satisfied. After serving your portion, if there are leftovers, put them away immediately. The less you see, the less you'll eat.
