7. Grab a small plate
In Mindless Eating, Wansink says one of the secrets to eating more healthfully is to become an illusionist. We tend to serve ourselves more when we use big plates because they make the food look small. But when we use smaller plates, we perceive that we’re getting more food. “If you take a medium-sized hamburger and serve it to a person on a saucer, they estimate it as having 18 percent more calories than if you serve it to them on a normal-sized plate,” he writes. Trick yourself by using salad- or lunch-size plates at mealtimes instead.
