Must-Have Products to Keep Portions Under Control

For snacks you pack on the go, bring along one of these Steeltainer Containers ($14). They're lightweight and made of stainless steel so they won't break, and the lid clamps down so it's 100 percent leak-proof. The divider in the middle can be moved to accommodate two different-size snacks such as cheese and crackers or grapes and dry cereal. It comes in blue and white.
