Effects of obesity on survival from age 35 years in males:

Graph showing effects of obesity on survival

Comment: This graph shows the effects of becoming obese by middle age on the probability of surviving to different ages. Reaching a weight one third more (BMI 32) than a healthy trim weight (BMI 24) cuts life expectancy by about 3 years. The graph is about men, but for women the reduction is much the same.

Source: These findings come from the Prospective Studies Collaboration, which analysed data on nearly 1 million adults in 56 epidemiological studies, mostly in western Europe and North America.
