Using Eurobarometer data on 29 countries, this paper provides cross-sectional evidence that overweight perceptions and dieting are influenced by a person’s relative BMI, and longitudinal evidence from the German Socioeconomic Panel that well-being is influenced by relative BMI. Highly educated people see themselves as fatter − at any given actual weight − than those with low education. These results should be treated cautiously, and fixed-effects estimates are not always well-determined, but there are grounds to take seriously the possibility of socially contagious obesity. %K mental health %K dieting %K peer effects %K happiness %K imitation %K comparisons %K body mass index BMI %K well-being %K obesity
