Obesity rates climbing worldwide, most comprehensive global study to date shows -- ScienceDaily
The whole world s getting heavier. Interestingly, though, the USA, which is the world's fattest nation, has plateaued out over the past 5 or so years. Other countries are catching up. My country is bad, though I suspect the reason is that NZ has more polynesians than any other place, and polynesians are the worst. (They have a metabolism that conserves calories - a genetic difference).
What of the future? Will the rest of the world end up where the USA is, with a third of the population obese, and then plateau out also? Or will some become even more obese?
