Je suis tombé sur le site de Shermer et voilà ce que j'y ai trouvé : http://www.skeptic.com/eskeptic02-24-05.html#a.
N'étant pas un expert en nutrition mais ayant eu quelques cours de pharmaco sur l'obésité, je dois avouer être un peu surpris par tout cela.
En bref et pour ceux qui n'aiment pas l'anglais :
La mortalité est plus élevée chez les gens qui sont en en dessous de la norme de poidsque chez ceux qui sont obèses.
Les études montrant que l'obésité est une cause de mortalité ne prennent pas en compte la quantité de sport que les gens font et quand elles le font, c'est de manière innapropriée.
Les originaux :
The data from this study indicate that underweight men had nearly twice the mortality of normal and overweight men, and that although those who fit into the obese category showed an increased risk when compared to normal and overweight men, they still fared better than men in the thin cohort.
... the largest epidemiological study ever conducted, the data show that the highest life expectancy occurred in individuals who are overweight by our current standards and that the lowest life expectancy occurred with those who were defined as underweight. Furthermore, the individuals observed in this study who fit into what is deemed the ideal weight range had a lower life expectancy than those who were classified as obese.
Over the past twenty years, scientists have gathered a wealth of evidence indicating that cardiovascular and metabolic fitness, and the activity levels that promote such fitness, are far more important predictors of both overall health and mortality risk than weight. Yet none of the studies most often cited for the proposition that fat kills makes any serious attempt to control for these variables. And indeed, when studies of this type do claim to make such attempts, the methodology employed can be almost farcical.
