According to this interactive map, Israeli women are just slightly more overweight then Israeli Men (27.14, 27.29 respectively). One thing that does stand out- as far as I can see it is rare in the western world for women to have a higher average BMI then men (So far I noticed only Romania as a European country with the same result) .I have no idea why we seem to be the exception to the rule. Perhaps it has something to do with the large Arab population? Many Arab countries seem to have the same results.
Second thing which surprised me..Britain is the only Western country which has a normal BMI? How is that possible with a nation who's national food is Fish and Chips?
