When I know I'll be eating out, I try to drink water or green tea and have a light snack before going. Then, I'll try to psych myself up before actually entering the restaurant, thinking about the healthier things I know that restaurant has that taste good. That way, I don't go in with my mind on french fries dipped in ranch dressing and a Coke. Some places have those little "healthy option" symbols next to some of their items...scan through those first, without even looking at what else is on the menu. Typically you can find something that you'll enjoy, that's not going to completely ruin your diet. OR...order what you want, but get a to-go box before you start in on your meal. Put a large portion of it in the box to take home for later, or for a family member...restaurant portions are HUGE, and it's so hard to stop eating once you get started. Hope this helps! Man I love eating out.
