Prostate cancer is in Germany with approximately 25% of all cancers the most common cancer among man. Assumably there will be an increase in prostate cancer in the next few years because of demographic factors. The progressive metastatic prostate cancer often develops an androgen resistance. This so-called Castration-Resistant Prostate Cancer (CRPC) is not responsive to androgen deprivation therapy. Depending on symptoms and progression first-line chemotherapy - docetaxel and abiraterone are available.
Intermittent fasting as a form of caloric restriction has been studied most extensively experimentally in recent years. It showed consistent beneficial effects on relevant inflammatory and oncological pathways. In the field of preclinical oncology research groups have recently focused on intermittent fasting with chemotherapeutic treatment and promising experimental data have been published. In summary, the combination of fasting and chemotherapy was more effective in various cancer animal models than chemotherapy alone.

60h-modified fasting (36h before and 24h after chemotherapy)
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.
Active Comparator: Control
Participants of the control group will receive an individual nutrition training and in small groups according to the Mediterranean diet.
