Research shows that using smaller plates makes people serve themselves less, but still feel content after eating. In fact, switch from a 12-inch plate to a 10-inch plate, and studies show you’ll eat about 20-22% less calories per meal. The effect has to do with seeing a full plate; similarly a sparsely-filled plate can make you feel hungry.

Here's the problem with that recommendation we often fail to mention: small plates are hard to find. You can find lunch plates or salad, which are about 8 inches. (I actually prefer these.) You can find cocktail plates meant for parties and entertaining. These are often 6 to 8 inches, too. "Dinner" plates hover around 12 inches, though I've seen some that are upwards of 14. But the 10-inch plate eludes many.

While it may all be mind games, play the plate size trick it to your advantage by using smaller plates and bowls so servings appear larger. To help you downsize your plates and your waist, we gathered our favorite rightsized plates you can buy today:
