How to Stop Emotional Eating

7 Ways to Stop the Trigger

When you notice that you are about to eat because you don't feel good, look for healthy things you could do until the urge to eat passes. For instance:

1. Talk to a friend.
2. Read a book or magazine, or listen to music.
3. Go for a walk or jog.
4. Meditate or do deep breathing exercises.
5. Play a game.
6. Do housework, laundry, or yard work.
7. Write an email.

Keep a food diary. Write down what and when you eat, and what thoughts or emotions you have at each meal or snack. You may find patterns. For instance, you might notice that you eat for social reasons, such as when other people encourage you to eat or to fit in with a group.
You may also want to work with a mental health profession. It's a good place to plan other ways to handle your emotions and how you relate to food.
