Here's my dilemma... Should I go and get the somewhat healthy meal of a chicken wrap with lots of veggies? Or go and get me a big ass Italian sub from my favorite local sub shop? They are both pretty tasty and satisfying. And both cost the same.
 
If I get the wrap, I'll feel good and energetic and be productive for the rest of the afternoon. I'll go home, all ready to finish the laundry and other assorted household chores and be motivated enough to make a healthy dinner from scratch. There might even be the desire to go for a bike ride later on in the evening.  
 
If I get the Italian sub, I'll feel good and full for the first hour, but then I'll descend into a post-lunch funk where I'll want to curl up under my desk (Costanza-style) and take a nap. Nothing will really get done for the rest of the day and I'll go home early and sit on the couch for the rest of the night, neglecting the laundry and weeding that needs to be done. Dinner will probably either be pizza delivery or a quart of ice cream.
 
What's my decision? Viva la Italian Sub!
