Fat men less likely to commit suicide

A new study found that among men, risk of death from suicide is strongly inversely related to BMI (Body Mass Index), not to height or to physical activity. In fact, obese men are 42% less likely to commit suicide than thin men are.

This finding appears consistent with our commmen sense - (1) fat men have more insulin, which means more serotonin, which means less depression. So fewer fat men are depressed enough to commit suicide. (2) severe depression makes you thinner before it makes you kill yourself.
