Weight gain and fat accumulation are common after BC diagnosis; moreover, weight gain during the treatment decreases the survival rate and increases the risk of recurrence in breast cancer survivors (BCS). To reduce the risk of second primary cancer or BC recurrence, and all-cause mortality in BCS, multiple interventions have been investigated to obtain reduction in weight, BMI and\/or waist circumference. The aim of this narrative review is to analyze evidence on BCS for their risk of recurrence or mortality related to increased weight or fat deposition, and the effects of interventions with healthy dietary patterns to achieve a proper weight and to reduce fat-related risk. The primary focus was on dietary patterns instead of single nutrients and supplements, as the purpose was to investigate on secondary prevention in women free from disease at the end of their cancer treatment. In addition, BC relation with insulin resistance, dietary carbohydrate, and glycemic index\/glycemic load is discussed. In conclusion, obesity and overweight, low rates of physical activity, and hormone receptor-status are associated with poorer BC-treatment outcomes. To date, there is a lack of evidence to suggest which dietary pattern is the best approach for weight management in BCS. In the future, multimodal lifestyle interventions with dietary, physical activity and psychological support after BC diagnosis should be studied with the aim of reducing the risk of BC recurrence or mortality.<\/jats:p>","DOI":"10.3390\/nu14030476","type":"journal-article","created":{"date-parts":[[2022,1,23]],"date-time":"2022-01-23T20:34:40Z","timestamp":1642970080000},"page":"476","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":41,"title":["Breast Cancer Diet \u201cBCD\u201d: A Review of Healthy Dietary Patterns to Prevent Breast Cancer Recurrence and Reduce Mortality"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8186-039X","authenticated-orcid":false,"given":"Edda","family":"Cava","sequence":"first","affiliation":[{"name":"Unit of Dietetic and Clinical Nutrition, University Hospital \u201cMaggiore della Carit\u00e0\u201d, Corso Mazzini 18, 28100 Novara, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3215-5747","authenticated-orcid":false,"given":"Paolo","family":"Marzullo","sequence":"additional","affiliation":[{"name":"SCDU Endocrinology, Department of Translational Medicine, University of Eastern Piedmont, Via Solaroli 17, 28100 Novara, Italy"},{"name":"Laboratory of Metabolic Research, IRCCS Istituto Auxologico Italiano, 28824 Piancavallo, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Deborah","family":"Farinelli","sequence":"additional","affiliation":[{"name":"Unit of Dietetic and Clinical Nutrition, University Hospital \u201cMaggiore della Carit\u00e0\u201d, Corso Mazzini 18, 28100 Novara, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alessandra","family":"Gennari","sequence":"additional","affiliation":[{"name":"Division of Oncology, University Hospital \u201cMaggiore della Carit\u00e0\u201d, Department of Translational Medicine, University of Eastern Piedmont, Via Solaroli 17, 28100 Novara, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chiara","family":"Saggia","sequence":"additional","affiliation":[{"name":"Division of Oncology, University Hospital \u201cMaggiore della Carit\u00e0\u201d, Department of Translational Medicine, University of Eastern Piedmont, Via Solaroli 17, 28100 Novara, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8798-1224","authenticated-orcid":false,"given":"Sergio","family":"Riso","sequence":"additional","affiliation":[{"name":"Unit of Dietetic and Clinical Nutrition, University Hospital \u201cMaggiore della Carit\u00e0\u201d, Corso Mazzini 18, 28100 Novara, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9660-5335","authenticated-orcid":false,"given":"Flavia","family":"Prodam","sequence":"additional","affiliation":[{"name":"SCDU Endocrinology, Department of Translational Medicine, University of Eastern Piedmont, Via Solaroli 17, 28100 Novara, Italy"},{"name":"Department of Health Sciences, SCDU Endocrinology, Department of Translational Medicine, University of Piemonte Orientale, Via Solaroli 17, 28100 Novara, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,1,21]]},"reference":[{"key":"ref_1","unstructured":"World Cancer Research Fund\/American Institute for Cancer Research (2021, November 25).
