“…Alexithymia, reported in both fibromyalgia [23,36,38,76,87,103,104] and obesity [20,22,[32][33][34][35], may be described not only as a marker of global emotional difficulties [105], but also as a general failure of interoception (i.e., the ability in perceiving and recognizing the internal state of the body [20,[106][107][108]). In other words, because of the presence of alexithymia, individuals might misattribute the origin of their bodily experience [38] and/or showed difficulties in converting own somatic sensations in feelings and cognitions [106]; this difficulty may in turn interfere also with the ability to identify others' emotional states [76,[109][110][111][112][113][114], with effect on the emotional contagion and empathy (as preliminary observed in fibromyalgia [23,115] and obesity [116]). Indeed, it should be considered that the recognition of facial emotions in others automatically activate a representation of a similar psychophysiological state in the observer [117].…”
