Figure 1 The ‘vicious cycle’ model of obesity and cognitive decline. This vicious cycle model suggests that eating a Western diet — i.e. one high in saturated fats and sugar — produces pathologies in the hippocampus that interfere with the inhibitory control of eating behavior, thus reducing the ability to resist the power of environmental cues associated with food. This may ultimately result in overeating, excess weight gain, and more severe forms of cognitive impairment. (Adapted from [10,17].)
