For many people, dinner is only the start of their nighttime eating. There's nothing wrong with a healthy snack such as fruit, plain popcorn or whole-wheat toast with a little jam a couple of hours after dinner. However, nighttime eating is a problem when you eat large amounts of food or foods high in saturated fat, sodium and calories like cookies, chips, full-fat ice cream, sandwiches or leftovers.
If you're an emotional eater, you can learn other ways to react to your emotions. Emotions usually don't last long — often just 10 minutes to an hour — so you only need to distract yourself from eating for a short time, until the emotion passes, like going for a 10-minutes walk around the block.
