A portion is the amount of one food you eat in one sitting. Many people eat more than they need, especially when eating out or getting takeout. Try these tips:

* Avoid eating in front of the TV, computer, or other screen. You may not notice how much you are eating if you are distracted.
*  Read the Nutrition Facts label found on food and drink packages to see how many calories and how much fat are in a single serving size of an item.
