Brief Summary:
This research will examine the feasibility of conducting a strict whole-food, plant-based dietary intervention in women with stable metastatic breast cancer currently undergoing conventional treatments. In addition, this research will provide preliminary data on dietary intakes and the effect of plant-based nutrition on numerous outcomes reflecting cancer prognosis and overall health using advanced imaging, various blood biomarkers linked to cancer progression, and numerous symptom questionnaires.

Arm Intervention/treatment
Experimental: Intervention group
Subjects are provided three meals daily, attend weekly office visits, take a daily multivitamin.
Behavioral: Plant-Based Diet
Women will be provided with 3 meals daily, delivered to their home, for 8 weeks, along with a multivitamin, and will attend weekly office visits.

No Intervention: Control Group
Women instructed to maintain current intake and take a provided multivitamin.

Primary Outcome Measures :
  1. Recruitment [ Time Frame: 1 year ]
    Percentage of women who are randomized in the study out of the all women approached.
