This clinical trial studies the effects of a diet and physical activity intervention on blood measures of lipids and insulin resistance in patients with prostate cancer undergoing radiation therapy (RT) and androgen deprivation therapy (ADT). ADT effectively slows the growth of prostate cancer cells, thereby enhancing the therapeutic effectiveness of RT. Despite the clinical gains, ADT leads to an array of side effects including insulin resistance, abnormal lipid levels, weight gain, increased visceral fat mass coupled with increased muscle wasting, and quality of life deterioration. A diet and physical activity intervention may intercept or prevent the abrupt metabolic and physiologic changes caused by androgen deprivation therapy in prostate cancer patients receiving ADT and RT.
