Here are some ideas. These may take some discipline and household rule changes but may be worth it in the long run.:
1. If your favorite show is during dinner time, either move your dinner time to before or after or record your show and watch it later.
2. Make a house rule that food is only allowed in the kitchen and remove any TV or other screen you may have from the kitchen. No more potato chip crumbs to pick up throughout the house!
3. Set time limits of when screens can be on or used during the day.
4. Instead of eating while watching TV, exercise. For example, walk in place as you watch the news in the evening.
We live in a society where screens seem to call our attention. See if you can make screens and eating not connected to each other.
