Use Your Hands to Control Portion Sizes

Do you look at the label when you pour a bowl of cereal? When you do, you'll see a variety of nutritional facts including serving size. Yet many confuse serving size with portion size: Portion size is the amount you choose to dish out, while serving size is the specific measured amount listed on the label.

The two work together like this: "If the package has 3 servings, and you eat the whole package, you must multiply the nutrition information times three. That would be your portion," according to EMH-healthcare.org.

While serving sizes have stayed about the same in the past 50 years, portion sizes have ballooned; restaurant meals are 250 percent larger than a standard portion, according to Portion Size Me: Downsizing Our Consumption Norms. Not to mention American's underestimate their portion sizes by as much as 25 percent thanks to larger plates, bowls and glasses.

Don't underestimate your portions anymore; use this serving size guide to eat only as much as you need.
