My opinion:
"Hungry Girl" specializes in low calorie junk food.
I get the Hungry Girl emails, and they are all about creating low calorie dips, lower calorie replacements for Dairy Queen Blizzards and Taco Bell burritos...and the latest snack bars, etc. on the market.
I would go to her website and maybe get the occasional recipe there...but if you actually want a COOKBOOK, I would maybe go for a Weight Watchers one, or other lower calorie/lower fat cookbook. Something where there are actually healthy main dishes, side dishes and such along with the desserts.
