Randomized study including two parallel groups: patients from the advanced chronic kidney disease (CKD) consulting room of the Malaga University Regional Hospital and controls. The main objective is to assess the clinical response (quality of life, nutritional status, functional capacity, and disease knowledge) of advanced CKD patients who undergo an individualized dietary intervention and a nutritional education program (group workshops) using motivation coaching techniques, compared to controls who receive general hygiene-nutritional education at every visit.~Both groups will be composed of 54 participants. The control group will be provided general dietary and lifestyle recommendations (standard procedure in the nephrology consulting room), whereas the intervention group will receive treatment and individualized dietary follow-up using coaching techniques, supported by information and communication technologies, and will participate in a nutritional education program composed of four on-line sessions.~Two visits (basal and three months after) will be scheduled during the study to obtain and analyse the data. Moreover, in these visits researchers will collect a blood sample in order to perform an assessment of the metabolism, inflammation, and oxidation, and a stool sample in order to evaluate the gut microbiota.
