About Rationally Speaking
Rationally Speaking is a blog maintained by Prof. Massimo Pigliucci, a philosopher at the City University of New York. The blog reflects the Enlightenment figure Marquis de Condorcet's idea of what a public intellectual (yes, we know, that's such a bad word) ought to be: someone who devotes himself to "the tracking down of prejudices in the hiding places where priests, the schools, the government, and all long-established institutions had gathered and protected them."

Atkins: the fad, the bankruptcy
This isn't really surprising, as the American public is infamous for diet fads that last a season, or slightly longer than the average dieter's ability to actually stick to any health-conscious regime. As a commentator put it today on National Public Radio, people figured out that life without bread and pasta is just not as much fun. As an Italian (with no weight problem, at the moment!) I couldn't agree more.
The thing abot the Atkins (or, for that matter, many other popular diets), is that there is little -- if any -- scientific research to back up its claims of effectiveness, and especially of long-term health (you may lose some weight in the beginning, but is your heart going to be ok with all the cholesterol you keep gulping down in large portions?). This, of course, hasn't stopped even some of my more skeptical friends to embrace it, either because somebody told them it worked (science by anectode -- never fails), or because it just felt good to suddenly be free to eat a lot of formerly "forbidden" meat (I guess not many vegetarians takers).
There are two rather obvious, and yet so often overlooked, things about dieting. First, there is no magic bullet, no single-chemical or simple solution to what is, after all, a complex methabolic problem. Like many things in life, there is a way to do it, but it ain't painless and straightforward. Second, the "secret" to lose weight is (but don't tell anyone!): eat less and move your butt more. Or, to put it more scientifically: it's a matter of thermodynamics, baby, if you want to lose weight, increase your ouptut and decrease your input. Believe me, it works, I've done it! (And it's backed by the most solid principle in science: the second law of thermodynamics.)
