I break down a new large clinical trial that examined weight loss outcomes in women with stage II–III breast cancer after treatment. We explore what the year-long lifestyle intervention included, how much weight participants lost, and why average numbers don’t tell the full story. I discuss differences in weight loss by menopausal status and race, common frustrations survivors experience, and where GLP-1 medications may fit into weight management after breast cancer.
