Alternate Day Fasting After Surgery for Patients Undergoing Chemotherapy

"Participants will alternate fasting days (FAST) with unrestricted eating (OFF, or Feast) days, for one week surrounding the start of each chemotherapy cycle. The participants will fast for two consecutive days in the middle of the ADF week - the day prior to chemotherapy start date, and chemotherapy day 1 for each cycle. Participants will consume regular diet (OFF/Feast) during other days 5-18 of each cycle."
