* Participants in the intervention group will be asked to follow a fasting schedule that consists of not eating for 16 hours a day followed by normal eating for the remaining 8 hours of the day for 5 days in a row followed by 2 days of regular eating each week. conditions: Epithelial Ovarian Cancer studyType: INTERVENTIONAL phases: NA allocation: RANDOMIZED interventionModel: PARALLEL interventionModelDescription: Two arm, randomized, controlled study. primaryPurpose: SUPPORTIVE_CARE masking: SINGLE maskingDescription: Participants' cross-sectional skeletal muscle areas will be measured. Measurements will be performed on CT scans obtained within 4-6 weeks of treatment initiation (with a 7-day screening window) by a fellowship-trained, experienced radiologist and imaging specialist in consensus who will be blinded to participant clinical variables and treatment. whoMasked: OUTCOMES_ASSESSOR count: 20 type: ESTIMATED name: Intermittent Fasting name: Neoadjuvant chemotherapy measure: Intermittent fasting compliance as measured by serum glucose laboratory testing measure: Intermittent fasting compliance as measured by ketone laboratory testing measure: Intermittent fasting compliance as measured by IGF-1 laboratory testing measure: Intermittent fasting compliance as measured by insulin laboratory testing measure: Intermittent fasting compliance as measured by serum glucose laboratory testing measure: Intermittent fasting compliance as measured by ketone laboratory testing measure: Intermittent fasting compliance as measured by IGF-1 laboratory testing measure: Intermittent fasting compliance as measured by insulin laboratory testing measure: Intermittent fasting compliance as measured by serum glucose laboratory testing measure: Intermittent fasting compliance as measured by ketone laboratory testing measure: Intermittent fasting compliance as measured by IGF-1 laboratory testing measure: Intermittent fasting compliance as measured by insulin laboratory testing measure: Intermittent fasting compliance as measured by self-reported assessment measure: Intermittent fasting compliance as measured by self-reported assessment measure: Intermittent fasting compliance as measured by food diary measure: Intermittent fasting compliance as measured by food diary measure: Intermittent fasting compliance as measured by food diary measure: Pre body composition measure: Post body composition measure: Chemotherapy related toxicity at Cycle 2 measure: Chemotherapy related toxicity at Cycle 3 measure: Chemotherapy related toxicity at Cycle 4 measure: Chemotherapy related toxicity at post treatment measure: ESAS Score at Enrollment measure: ESAS Score at Cycle 2 measure: ESAS Score at Cycle 3 measure: ESAS Score at Post Treatment measure: SF-125 Score at Baseline measure: SF-125 Score at Cycle 2 measure: SF-125 Score at Cycle 3 measure: SF-125 Score at Post Treatment measure: Pre Quality of Life (QLQ-C30) Score at Baseline measure: Post Quality of Life (QLQ-C30) Score Post Treatment measure: Pre Functional Assessment (FACT-O) Score at Baseline measure: Post Functional Assessment (FACT-O) Score Post Treatment measure: AIM Survey Score at Cycle 2 measure: AIM Survey Score at Cycle 3 measure: AIM Survey Score at Post Treatment sex: FEMALE minimumAge: 18 Years stdAges: ADULT stdAges: OLDER_ADULT hasResults: False
