This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This study is testing whether time-restricted eating (eating all your food within the same 8-hour window each day) can help women with breast cancer during chemotherapy. Researchers believe this eating pattern might help reduce side effects, improve how well chemotherapy works, and prevent weight gain that commonly happens during cancer treatment. The study will compare time-restricted eating alone to time-restricted eating combined with a Mediterranean-style diet (which focuses on vegetables, whole grains, fish, and healthy oils).
During chemotherapy, women with breast cancer often gain weight despite trying to eat well, and this can affect their health and risk of cancer returning. Some early research suggests that eating within a shorter time window during the day might help the chemotherapy work better and reduce side effects, but this approach hasn't been properly tested in breast cancer patients yet.

If you join this study, you'll be randomly assigned to one of three groups: eating all your food within an 8-hour window each day, eating within that same 8-hour window while following Mediterranean-style dietary guidelines, or continuing your normal eating habits as standard care. You'll need to keep track of what you eat and how you feel, and participate in regular check-ins with the research team throughout your chemotherapy treatment to monitor your health, weight, and how well you're tolerating the program.
