One of the major differences between here and the US is frequency of obesity and the size of people in general. Whereas my weight was considered fairly normal in the US, I tend to be more on the big side here. This is probably more of a US issue than that Quebec is thinner than usual. The three times I returned to the US from living in France, it was the one thing that always stood out and was almost a bit surprising. Just getting off the plane, I immediately noticed the difference. The odd thing was when I was going to France that I did not remark that people were thinner.
Though now living here in Quebec, I do notice the difference in the people I see on the street day to day. I would go as far as saying that the difference is about 20 pounds. If you live in the US and imagine yourself minus twenty pounds, that's the difference. The opposite applies for people here in Quebec. Now there are the normal difference in each population. Suburbanites tend to be bigger than urbanites. People tend to gain weight as they grow older getting that beer belly or whathaveyou. People who go through major crisis sometimes gain weight. And sometimes it really is genetic, though I think many people are trying to use that as an excuse. Not that being overweight is the fault of that person, though measures can be taken.
The people I see that I have still not gotten used to are those with thighs as thin as my upper arm. It just seems unnatural, like they should have trouble walking or something. Thing is it's probably more natural, and maybe just genetic.
What are the reasons? Here's just a few. First the portions you get when you go out to eat are made for one person to eat. They don't give you enough for two meals as it is becoming the trend in the US. Also I am pretty sure there is no supersize here. Second, people seem to exercise more here. I don't think people run for exercise as much, but it seems like bicycles are everywhere. Though I don't know if they are making up for the lack of exercise over the winter. As far as diets, people seem to eat pretty much the same types of food as the US. Lastly, part of it can be genetic. French Canadians tend to be smaller that the rest of Canada from what I know. Or it could be just the dietary tradition.
Unfortunately, after two years here, I still have not followed along with the population and brought my weight down. Hopefully that will change.
