How is obesity associated with happiness? Evidence from China

Happiness is a universal goal that people pursue. Studies of the relationship between obesity and happiness have shown mixed findings. It is uncertain whether an optimum BMI level exists and at what level obesity interferes or interacts with happiness. Guided by the Circle of Discontent Theory, we examined the relationship between obesity and happiness among Chinese residents using the 2014 China Family Panel Studies data. The results reveal an inverted U-shaped relationship between BMI and happiness, with obesity associated with happiness through physical appearance, health, and income. The socioeconomic conditions for the appropriate weight to achieve happiness are discussed.
