Effects of Nutritional Intervention and Exercise on Anthropometric and Metabolic Parameters in Moroccan Women with Breast Cancer: A Pilot Study

This study examines the effects of a dietary and physical activity intervention on body composition and metabolic parameters in Moroccan women with breast cancer. Conducted as a pilot cohort study, 37 women with breast cancer were recruited between 2017 and 2019 at the Hassan II Regional Hospital Center and the Agadir Regional Oncology Center. Participants completed a 12-month nutrition and physical activity intervention. The mean age was 47.92 ± 8.56 years. At the end of the intervention, participants experienced a mean weight loss of 11%, resulting in a significant reduction in normal weight and obesity rates from 35.14% and 32.43% to 57% and 5%, respectively (<i>p</i> < 0.05). Waist and hip circumferences were reduced by 10%, and there were significant reductions in body fat and visceral fat. Improvements were also seen in metabolic markers, with significant reductions in total cholesterol, LDL-C, blood glucose and HbA1c levels (<i>p</i> < 0.05). Lean mass was preserved and HDL-C showed a significant increase (<i>p</i> < 0.001).
