Telling the us what we already knew, a new report says that Manhattanites are thinner than average Americans: Just 34% of white Manhattan residents are overweight, versus 64% of all Americans. The incidence of obesity increases with the other boroughs, leading to hypotheses that white Manhattanites are walking more than their outer borough counterparts or that they are richer and more well-educated, but Gothamist knows why they are thinner - the skinny, Atkins/South Beach/Zone/anorexia dieting socialites and magazine editors are throwing the whole study off.
