Fark linked up another journalist's tale of going on his own "McDiet". Because he was sane in his menu choices (the other guy ordered the biggest meals he could find and was on a 5000 calorie per day diet), not only did he not get sick, he actually lost weight. The reaction of his female co-workers was telling:

[The revelation I lost weight] prompted the majority of women I told to issue the following statement, separately but in a clearly coordinated campaign: "I hate you." My reminders that they live longer and are better equipped to survive the famine that Americans appear to be stocking up for didn't earn me any points.

As one who has just been indirectly put on the South Beach (Long Beach? Malibu Beach? Life's a Beach?) diet, I can definitely sympathise.
