Abstract

Food insecurity relates to fat storage, but cannot explain fat storage in excess of levels optimal for buffering – that is, obesity. However, factors related to food unpredictability in the past, including stress, disease, micronutrient content of food, and physical activity, may cue physiological processes that change intake or fat deposition even in the absence of actual food unpredictability.
