I like LadyBelle's answer about how people die all the time. Correlation does not equal causation, people, no matter how much the anti-low-carbers would like it to.

Even if these 3-4 deaths were directly related to Atkins, there are hundreds of thousands of healthy people who've lived long lives with the help of a low-carb diet. Besides, how many traditional low-fat dieters have died of heart attacks, clogged arteries, and the like? Millions!
