Now the report: According to a study by researchers at Statistics Canada, Kaiser Permanente Center for Health Research, Portland State University, Oregon Health and Science University and McGill University published in the online journal Obesity, overweight (extra few pounds) people lives longer. This was based on studying the relationship between the BMI (body mass index) and death among 11,326 Canadian adults, the data extracted from Canadian National Population Health Survey over a 12-year period. The study reported that underweight people has a 70% higher chances of dying than people of normal weight while those morbidly obese people has a 36% higher chances of dying. The surprising finding is that overweight people have 17% lower chances to die as compared with people of normal weight.
