Pierce: If you're on a diet, take this fast-food trivia quiz

Did you know that two decades ago a typical restaurant cheeseburger had about 330 calories, but thanks to supersizing that's now doubled?

This little-known fact was brought to my attention during my Jenny Craig weigh-in last week as I was confessing to having caved to a Krystle craving. Maybe twice a year, I'll feel the need for one of those little steamed sliders, and this time it was unfortunately the same week I'd already been to Red Lobster.

Anyway, I again had gained 2 pounds, which I've again lost, so I've rocked back and forth between 13 and 15 pounds for the last four weeks.

To help me remember why fast food has supersized my thighs, my Jenny counselor kindly suggested I check out the following fast-food pop quiz in Jenny's Dining Out Success Guide.
