Currently, more than 1 billion adults around the world are overweight, and at least 300 million of them are clinically obese.

While obesity levels are below 5 percent in countries such as China, Japan, and certain African nations, many island nations are at the other end of the spectrum.
In fact, 9 of the top 10 fattest countries in the world, according to a recent GlobalPost list, are island nations. The other one…you guessed it…the United States. Here is how the fattest nations stack up:
1) Nauru: 95 percent 2) Micronesia: 92 percent 3) The Cook Islands: 92 percent 4) Tonga: 92 percent 5) Niue: 84 percent
6) Samoa: 83 percent 7) Palau: 81 percent 8) United States: 79 percent 9) Kiribati: 77 percent. 10) Dominica: 76 percent
