The first time that terms such as food addiction and addictive eating were mentioned was in 1956, in an article by T.G. Randolph. Recently, from a psychosomatic point of view, some authors have linked obesity and food addiction. Along with the concept of food addiction (derived from the similarities between the consumption of certain foods and “substance addictions”), a couple of questions seem to arise: What if it’s not just the particular food (the substance) that we are addicted to? Could it be that we are addicted to something else that makes us eat it? Thus, the concept of eating addiction has its own set of particulars. It brings the attention back to the individual and not the external substance (the food or ingredient). The focus on confronting the obesity problem should be moved away from the food itself (the addictive substance) to the person’s act of eating (the addictive behavior). Undoubtedly, there are many links between emotions and overweight/obesity. This chapter aims to review the current state of this field of study which is the emotional basis of obesity (at least a particular case of obesity and weight-related disorders).
