Abstract: A compound having antiestrogenic activity is used in a method for the treatment of BC or other estrogen-responsive tumors in a human patient, wherein the method comprises subjecting the patient to a fasting mimicking diet for a period of 24-190 hours while the patient is being treated with the compound having antiestrogenic activity, which can be a selective estrogen receptor modulator (SERM), a selective estrogen receptor downregulator (SERD) or an aromatase inhibitor (AI).

Abstract: A therapeutic combination of a compound having antiestrogenic activity and a CDK4/6 inhibitor is used in a method for the treatment of BC or other estrogen-responsive tumors in a human patient, wherein the method comprises subjecting the patient to a fasting mimicking diet for a period of 24-190 hours while the patient is being treated with the therapeutic combination, in which the compound having antiestrogenic activity can be a selective estrogen receptor modulator (SERM), a selective estrogen receptor degrader (SERD) or an aromatase inhibitor (AI).

Abstract: The use of and a method using a diet composition for enhancing lean body mass/muscle mass is provided. The diet composition includes a fasting-mimicking diet (FMD) component to be administered for a first time period of reduced calorie intake of 24 to 190 hours. The fasting-mimicking diet component provides less than 50% of the normal calorie intake of the subject with both protein restriction and sugar restriction. The diet composition can also include a re-feeding diet component to be administered for a second time period. Characteristically, the re-feeding diet component providing 60-100% of the normal calorie intake of the subject. Advantageously, the fasting-mimicking diet component and the re-feeding diet component are administered for multiple cycles.

Abstract: A tyrosine kinase inhibitor (TKI) for use in a method for the treatment of cancer in a patient, wherein the method comprises subjecting the patient to reduced caloric intake, i.e a daily caloric intake reduced by 10-100%, including starvation, for a period of 24-190 hours and administering the tyrosine kinase inhibitor to the patient during such period; the tyrosine kinase inhibitor is preferably selected among Lapatinib, Crizotinib, Gefitinib, Erlotinib, Afatinib and Regorafenib.

Abstract: A diet composition for use in the prevention and/or the treatment of endometrial hyperplasia in a human subject is provided. It has a) a fasting mimicking diet component to be administered for a first period of time and providing less than 50% of the normal caloric intake of the subject with both protein restriction and sugar restriction; and b) a re-feeding diet component to be administered for a second time period, which provides 60-100% of the normal caloric intake of the subject, wherein the fasting mimicking diet component and the re-feeding diet component are administered over multiple cycles.
