Summary
Brief summary (as posted)
This study is to see how safe the use of short-term fasting is in breast cancer patients who will receive chemotherapy before undergoing surgery and to examine if the use of short-term fasting will decrease the side effects of chemotherapy and how much a tumor shrinks while receiving chemotherapy.

Inclusion Criteria: * Patients ≥ 18 years of age with histologically, and radiographically confirmed non-metastatic breast cancer with minimal tumor size over 1 cm (≥T1c lesion) to receive neoadjuvant chemotherapy recommended by the treating physician * For estrogen receptor (ER) strongly positive, human epithelial receptor (HER2) negative breast cancer, Oncotype Dx study is required. Patients with low recurrence score will be excluded in the study. * Eastern Cooperative Oncology Group (ECOG) performance status score \< 1 * Absolute neutrophil count \> 1500 mm3, platelet count ≥ 100×109 L, hemoglobin ≥ 8.5 g/dL * Serum creatinine ≤1.5 times the upper limit of the normal range, total bilirubin ≤ 1.5 X ULN (≤ 3 mg/dL if clinically diagnosed with Gilbert syndrome) AST/ALT ≤ 2.5 X ULN (AST/ALT ≤ 5X ULN if clinically diagnosed with Gilbert syndrome) * Willing to provide blood samples for correlative research purposes * Women of child-bearing potential (i.e., women who are pre-menopausal or not surgically sterile) must be willing to use an acceptable contraceptive method (abstinence, oral contraceptive or double barrier method) for the duration of the study and for 30 days following the last dose of study drug, and must have a negative urine or serum pregnancy test within 2 weeks prior to beginning treatment on this trial. Exclusion Criteria: 1. Uncontrolled cardiac disease, such as angina, hypertension or significant arrhythmias, congestive heart failure (NYHA grade 2 or more or LVEF \< 40% on any prior assessment).

Clinical signs or symptoms of GI obstruction and/or requirement for parenteral hydration or nutrition 7. Inability to complete informed consent process and adhere to the protocol treatment plan and follow-up requirements 8.
