The RECHARGE Low Carbohydrate Diet Trial for Metastatic Cancer

This study is for people whose cancer: * has resisted chemotherapy * are taking a break from chemotherapy * or are looking for an alternative to the toxic effects of chemotherapy The trial is looking to see if a very low carbohydrate diet can inhibit the growth of certain cancers. The two major goals of the RECHARGE study are to determine: * whether a very low carbohydrate diet can help participants reduce the amount of cancer in their bodies (as measured by a PET scan at the beginning and end of the study) * whether participants can feel well while maintaining their weight on a very low carbohydrate diet This research study is for people with advanced cancers who decline chemotherapy or want to take a break from chemotherapy and have cancers that primarily feed on blood sugar. Examples of such cancers include metastatic breast cancer, colon cancer, cervical and uterine cancers, ovarian cancers, and many others. The investigators' intervention consists of a 28-day diet of high protein foods such as fish, poultry, meats, eggs and cheese as well as plenty of vegetables. Participants may eat as much of the high protein foods as they wish and can eat up to two cups of vegetables per day. Participants strictly eliminate carbohydrate-containing foods. These foods include all starches and sweets (breads, pasta, rice, potatoes, cereals, fruit, cakes, candies, soda with sugar, etc.).
