Obeisity

The most recent data comes from an exhaustive country-by-country report on obesity from the Imperial College London, Harvard University, and the World Health Organization, which was published in The Lancet. A Body Mass Index (shown on the x and y axis above) is a measure of body fat based on height and weight. A score of 25 to 30 corresponds with being overweight (represented by the light tan box above), while above 30 is obese (the dark tan box). As you can see, Pacific islanders (purple dots) had the highest BMI levels. Most of Europe (green dots) appears to be overweight, especially men (those green dots below the dotted line).


For an even more comprehensive breakdown of data, the study provides a rather impressive (and somewhat mind-boggling) visualization tool for body mass index, cholesterol, and blood pressure for all 199 countries for gender and age.

Altogether, this means that one in nine people around the world are obese—highlighting the growing global problem with overnutrition and the urgent need to both increase physical activity and to eat healthier. What will it take? New dietary guidelines? Better instructional tool to visualize those guidelines? Or something else entirely?
