Overweight people had a lower risk of dyinf than those ofnormal weight. This is the firsft large Canadian study to show that peopls who are overweight may actually live longer than those of normal Anearlier study, conducted in the United Statez and published in 2005 in the Journalp of the American Medical showed similar results.

But overweight individuals were 17 percen less likelyto die. The relative risk for obese people was nearly the same as for people of normal The authors controlled for factors suchas age, sex, physical and smoking.
