Like them or not, the Kardashians have become staples in popular culture. Most recently, sisters Khloe and Kim Kardashian have been pushing the QuickTrim diet product. I have to admit it makes me wary, since I believe a healthy diet and regular exercise are the safest and most effective ways to lose weight. And after reading a recent interview with Kim Kardashian, I'm even more dubious of the product line, since her new bod seems to be the result of major exercise.
