MORATO-MARTINEZ, Marina et al. A standardized, integral nutritional intervention and physical activity program reduces body weight in women newly diagnosed with breast cancer. Nutr. Hosp. [online]. 2021, vol.38, n.3, pp.575-584.  Epub 12-Jul-2021. ISSN 1699-5198.


breast cancer is the most common invasive cancer among women in developed countries. At diagnosis, approximately 70 % of women are overweight, and the additional weight gain that can result from the ensuing treatments has been associated with cancer recurrence and progression.


the main objective was to compare the effect of only a nutritional intervention (CG) with a nutrition education program (nutritional intervention, nutrition education, and physical activity) (IG) for 1 year.


a total of 65 women with breast cancer who had been evaluated at the Clinical Nutrition Department, La Paz University Hospital, Madrid, Spain were recruited into 2 groups: a control group (CG) and an intervention group (IG).


the IG showed a significant reduction in body weight (-1.87 ± 3.41 vs. 1.48 ± 2.01 kg, p < 0.05), BMI (-0.61 ± 1.40 vs. 0.65 ± 0.88 kg/m2, p < 0.05), total cholesterol (-32.92 ± 38.45 vs. -3.23 ± 39.73 mg/dl, p < 0.05), and low-density lipoprotein cholesterol (-35.29 ± 27.50 vs. 6.33 ± 40.70 mg/dl, p < 0.05). Both groups were shown to be more conscious of the importance of physical activity, with increased consumption of grains, fruits, oily fish, and dairy.


dietary interventions and physical activity were shown to be important to achieving several physical and physiological benefits that could reduce some risk factors associated with breast cancer recurrence and progression.
