Fasting and Nutritional Therapy in Patients With Advanced Metastatic Prostate Cancer

Patients realize a 60h-modified fasting (36h before and 24h after chemotherapy) with a dietary energy supply 350-400kcal per day with fruit and vegetable juices or, if not feasible, an established fasting-mimicking diet of 600-800 kcal according to Longo et al. Between chemotherapy a Mediterranean diet with nutrition training individually and in small groups by trained nutritionists at the Study Centre will be practiced.

Participants of the control group will receive an individual nutrition training and in small groups according to the Mediterranean diet.
