The advice for today: Enjoy eating out, but be aware if you are making regular trips, you may be compromising your waist line (not to mention your wallet. Face it. The food isn't cheap either).
Here is a great episode from Marketplace where they went to some of the big sit down chains and looked at their dishes.
As a reference, active adults typically need between 1600-2300 calories depending on size, age, gender and activity level.
Thanks to this episode, some chains are now posting their nutrition information. Go to Google and type in "[Name of Restaurant] Nutrition" and if it's out there, it should pop up.
