Obesity and poverty in childhood are widely studied phenomena and despite mixed results, some findings are without doubt: they come with various experiences of mental, physical and social harm, have therefore negative effects on the well-being of children, and they intersect in relation with race, class and gender. In this contribution we analyze child obesity and poverty from a philosophical social justice perspective, which has, to a large extent, so far neglected this topic. We show how they compromise social justice (...) and argue that there is an obligation to implement structural changes to assist the affected children and their families. However, we make also clear that such interventions must not happen in accordance to the current neoliberal fitness and health ideology and its related narrow individualism. (shrink)
