Men can fight food urges better

"Dr Andy Calder, a scientist at the MRC Human Cognition Unit at Cambridge University, said that given the relatively small number of people involved, it was hard to be certain whether the difference between men and women was genuine."<p>That's a severe problem with the reported study.<p><a href="http://norvig.com/experiment-design.html" rel="nofollow">http://norvig.com/experiment-design.html</a>

Correlation does not imply causation. Eg, brain scans could result from genetic differences or environmental (cultural) differences. All this study shows is that people who report cravings have different brain activity than people who do not.

I don't mean to be defending or attacking the validity of the study, and this is of course completely anecdotal, but my own personal experience would lead me to agree with the results.
