We are inviting women recently diagnosed with breast cancer and beginning chemotherapy to participate in the Lifestyle, Exercise And Nutrition (LEAN) Study. This research study will look at whether an exercise and nutrition program improves chemotherapy and endocrine therapy (Tamoxifen or Aromatase Inhibitor) completion rates and helps manage side effects. Half of the women in the study will be chosen at random to begin the exercise and nutrition program that involves 16 counseling sessions over one year in addition to their usual care. The other half of the women will be chosen at random to continue with their usual care.
The exercise program includes aerobic exercise, such as brisk walking 30 minutes per day, and a strength training program to be completed in your home. The nutrition program goals follow the US Dietary Guidelines focused on reducing sugar and fat in your diet while increasing the amount of fiber, fruits and vegetables that you eat. A Registered Dietitian will counsel you over the first year of the study on how to eat healthfully and exercise safely.
