How Baseballs and Lightbulbs Can Help with Portion Control
There are some steps you can take to battle the supersizing phenomenon. For many of us it is much easier to visualize a serving size by comparing it to an everyday object rather than to a measuring cup or scale. To that end, WebMd has an interactive tool that allows you to see several food items from each of the major food groups displayed on a plate and compared side-by-side with an object that represents a portion size. For example, a cup of vegetables is roughly the equivalent of a baseball. Or, a piece of fish is approximately the size of a checkbook.

There is also a pocket-size version you can print and keep in your wallet and a larger one you can post on your frig.
WebMd also recommends using smaller plates, dishing your food directly from the stove (not leaving serving bowls, platters, etc. on the table) and taking advantage of doggie bags. With the supersize portions at many restaurants you can now get lunch and dinner for the price of one. You can find more information on portion control at: Avoid Portion Distortion.
