BMI Over Time

Much like Gapminder highlighted in a previous post, the Washington Post has created a scatterplot of national body mass indices (BMI) overtime. Can you find a country whose national BMI decreased over a stretch of time contrary to almost every other country?
For an individual, body mass index is not the most valid index of how overweight you might be, despite the claims of the Centers for Disease Control. Keith Devlin points this out well in his column for the MAA.
