Researchers from Bristol University in England tracked 3000 people for 16 years and found a correlation between an increased body mass index (BMI) and a decreased risk of serious depression. It was determined that, for every 5 points a person's BMI increases, the risk of suicide is decreased by about 15%. They concluded that skinny people were more likely to be unhappy and commit suicide than people who were overweight/obese. Professor David Gunnell commented that they were surprised at the results because "there is a view that people who are overweight may be stigmatized and made to feel depressed."
