The mass media portrayal of a muscular body type ideal has been increasingly tied to men's body image dissatisfaction. We examined the role of self-determination theory's intrinsic life goals within this body image ideal and its potential as a moderator of this dissatisfaction. We first tested the moderating effect of intrinsic life goals on the link between magazine consumption and body image dissatisfaction via an online questionnaire (Study 1; N = 826), then experimentally manipulated these goals and exposure to images of muscular male models (Study 2; N = 150). A robust protective effect of intrinsic goals on body image satisfaction was observed – the relationship between magazine consumption and body image dissatisfaction was only significant among individuals with a lower level of intrinsic life goal orientation. When participants' intrinsic goals were momentarily heightened, they reported significantly less body image dissatisfaction, compared to those not receiving a strengthening of these goals. The results are the first to find a protective effect of intrinsic life goals on men's body image, and have important implications for intervention.
