This randomized phase II trial studies how well a controlled low calorie diet works in reducing side effects and increasing response to chemotherapy in patients with breast or prostate cancer. Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Eating a special diet with low calories may reduce the side effects of chemotherapy and improve the response to treatment
PRIMARY OBJECTIVES: I. To obtain preliminary estimates of the impact of a restricted diet on toxicity and efficacy of chemotherapy for breast and prostate cancer. II. To evaluate the compliance with a controlled diet intervention. III. To investigate changes in plasma insulin, glucose, insulin-like growth factor 1 (IGF1) and IGF binding protein (IGFBP) levels in subjects who consume a restricted diet compared to controls. OUTLINE: Patients are randomized to 1 or 2 treatment arms. ARM I: Patients eat a special low-calorie diet during 3 days prior to chemotherapy, during the 12 weeks of chemotherapy, and 24 hours after chemotherapy. Patients are provided with all meals and all food to be consumed and maintain a diary of the food consumed and appropriate amounts. Patients meet with the study dietician within 3 weeks of enrollment and prior to, or on the day of, their first course of chemotherapy on study and at the start of each subsequent course. ARM II: Patients eat a normal diet and receive dietary advice which may include consultation with a nutritionist. Patients maintain a diary of the food consumed and appropriate amounts.

Rate of chemotherapy-related toxicity
Occurrence of Grade 2+ non-hematologic symptomatic toxicity (fatigue, nausea and vomiting, anorexia, neuropathy, mucositis, cystitis, stomatitis), evaluated according to Common Terminology Criteria for Adverse Events version 4.0. The two arms will be compared, in terms of the proportion of patients with the occurrence of one of these toxicities.
Time frame: Up to 12 weeks
Tumor response
Measured using a summary statistic which includes Response Evaluation Criteria In Solid Tumors (RECIST) response, PSA response for men without measurable disease, pathologic complete response and clinical response for breast cancer patients. This rate will be compared between patients on the restricted diet and controls.
Time frame: Up to 12 weeks
