Which is the fattest country in the world?

Congratulations America - you are NOT the fattest country in the world...

Kuwait is, with an average BMI of 29.5. The U.S. is the heavyweight runner up with a 28.8 average BMI. Rounding out the top five heaviest nations are Trinidad and Tobago, Argentina, Mexico and Egypt.

Some of the skinniest countries may come as no surprise. Bangladesh, Eritrea and Ethiopia have the lowest BMIs and are also among the poorest nations.

So which countries are just right? 18 to 25 is considered the best BMI and Costa Rica, Canada, Switzerland, Brazil and Hungary all fit that bill.
