Effectiveness of a Combined Diet and Mindfulness Program on Weight Loss in Breast Cancer Survivors

[Research Background] Breast cancer ranks first among cancers in women worldwide, with overweight and obesity being one of the high-risk factors for breast cancer. Moreover, overweight individuals within the breast cancer patient population also face higher recurrence rates and mortality risks. Assisting overweight or obese breast cancer women in weight loss to promote their well-being was the initial idea behind this study. The most common weight loss strategies include dietary management and regular exercise. In recent years, more studies have shown that effective weight loss also requires psychological interventions. Therefore, this study will combine dietary, exercise, and mindfulness-related interventions to assist breast cancer patients in more effective weight management.

[Research Objectives] To compare the effectiveness of two intervention measures, the Diet, Exercise, and Mindfulness (DEM) model and the Diet and Exercise (DE) model, on weight loss, self-efficacy, mindfulness tendency, and quality of life.

[Research Method] The study will involve a quantitative study, which plans to carry out a randomized controlled trial (RCT). This trial will compare the effects of two intervention measures, the DEM model and the DE model, on weight loss, self-efficacy, mindfulness tendency, and quality of life.

[Expected Results] Through the intervention provided by this study, patients can engage in long-term online self-learning and supplementary learning after returning home, reducing the limitations of ineffective self-management learning caused by negative emotions, treatment side effects, and sequelae in the early stages of cancer. Healthcare professionals can also use scenario-based teaching materials produced by this study to guide breast cancer survivors with ineffective weight self-management skills in practicing the necessary skills. Additionally, through online learning, patients can learn and review without pressure, saving time on transportation, easing carbon foot print and relearning effective weight management skills; even if they have faced major life threats in the past, they can turn adversity into blessings, achieving a balance among physical, mental, and spiritual health.
