This is from the Canadian Bureau of Stats (or whatever you call it).
"According to the 2004 CCHS, 23.1% of Canadians aged 18 or older, an estimated 5.5 million adults, had a body mass index (BMI) of 30 or more, indicating that they were obese (Table 1) (see What is BMI?). This is significantly higher than estimates derived from self-reported data collected in 2003, which yield an obesity rate of 15.2% (see Methodology makes a difference). Another 8.6 million, or 36.1%, were overweight."
The totals add up to 59.2% and this is from 2004, so it stands to reason that it would have increased further by 2007. Nonetheless it is a ridiculously high rate and it's no longer even limited to the Western world.
