Do you often feel hungry even though you just ate? If this sounds like you, it may help to jot down everything you eat for one week. Also, write down what you were doing while you were eating. Then note how long it takes before you become hungry again. You may start to see some patterns. Some types of food just don’t keep you feeling full for long. Foods with a lot of added sugar and foods made up of simple carbs tend to digest very quickly, leaving you feeling hungry. Foods that are high in fiber, like whole grains, fruits, and vegetables, tend to keep you feeling fuller, longer.
