According to a new poll conducted in the United States between January and September 14, having a body mass index (BMI) that is not normal ups your likelihood of depression and other negative feelings.

The Gallup-Healthways Well-Being Index published its findings on September 17 and noted obese and underweight Americans are more stressed, worried, angry and sad than their overweight and normal weight peers.

The survey included 250,000 interviews and the data is based on "self-reported" emotions as well as height and weight. BMI denoted obesity (30+), overweight (25-29.9), normal weight (18.5-24.9) and underweight (-18.5).
