Too old by more than half. 2005. The discussion has moved on since. For more recent articles, I went to pubmed.com and entered "obesity longevity review." Four quick highlights: "Although a recent meta-analysis suggests that overweight individuals have significantly lower overall mortality than normal-weight individuals, these data are likely to be an artifact produced by serious methodological problems, especially confounding by smoking, reverse causation due to existing chronic disease, and nonspecific loss of lean mass and function in the frail elderly." https://www.ncbi.nlm.nih.gov/pubmed/24628815 https://www.ncbi.nlm.nih.gov/pubmed/24628815 "Utilizing novel models of visceral obesity, numerous studies have demonstrated that the relationship between visceral fat and longevity is causal while the accrual of subcutaneous fat does not appear to play an important role in the etiology of disease risk." https://www.ncbi.nlm.nih.gov/pubmed/23764746 https://www.ncbi.nlm.nih.gov/pubmed/23764746 Mexico: "Obesity and overweight have a strong effect on the incidence of T2D;this, combined with the large impact of diabetes on adult mortality, generates increases in mortality that translate into losses of 2 to 3 years of life expectancy at age 50." https://www.ncbi.nlm.nih.gov/pubmed/26172231 https://www.ncbi.nlm.nih.gov/pubmed/26172231 Trend: https://www.ncbi.nlm.nih.gov/pubmed/24913899 https://www.ncbi.nlm.nih.gov/pubmed/24913899
