About 5,7% of the Italian population is affected by T2DM, reaching a prevalence of 20% in people older than 75. According to several studies, T2DM has a social value, which leads to more imbalances in people who have a lower responsiveness, a difficulty in changing consolidated habits in more suitable behaviours. In such a scenery,the adherence to the nutritional therapy is about 35%, both co-pro-tagonists shaping up to be “losers”: the discouraged professional asking himself “why doesn’t he do what I told him?”, the patient with a health condition which has not improved. The difficulty in foreground consists in supporting a complex patient with a disease which “cannot be seen or felt”, whose seriousness may not be understood. The narrations which the patient does about the Diabetes make the picture even more complex, narrations reported by friends, relatives, confirmed by “Doctor Google”, filled with incorrect and untrustworthy pieces of information. Inside this picture, it may be useful to adopt a modality of leading the meeting based on the aware and strategic employment of communication, words and relationship; these tools do not find their place within the university course of the healthcare professionals: such modality may be the Nutritional Counseling. Exploration, active listening, avoidance of the barrier modes and of the psychological reactance, choice of the appropriate questions are just a few of the communicative techniques, typical of the Nutritional Counseling, which improve the ability of establishing the relationship with the patients, raising the adherence to the nutritional therapy. Through the Nutritional Counseling techniques it becomes possible to shift from the prescription of what patients have to do, to making possible to adopt the prescriptions making them their own; this leads to a change in the perspective which allows the patients to consider the prescriptions no more as limitations to their freedom, but as loyal travel companions in a new path.
