i don't think you can blame the climate. you have at least 6 good months in doha, if not 8. we have 4 to 6 terrible months in Canada, but many still find ways of exercising.
the diet is one reason. laziness is another. there are of course lazy people everywhere, but i see people here who can not even walk to their cars (parked 10-20 feet away) or who can't even go into a shop to get their food.
there may be a lot of overweight people in the US or UK, and to a lesser extent Canada, but you definitely don't see as many in Spain, Italy or France, where people walk a lot more and are more active.
