Diverse strategies, including dietary interventions and regular exercise, are potential strategies to combat obesity and its obesogenic consequences on the brain. Natural products like carotenoids such as lutein (Lu) have several positive impacts on human health and can help in reducing obesity. This study aimed to evaluate the combined effects of lutein supplementation and physical exercise (PE) on metabolic and hippocampal alterations associated with obesity. Wistar rats were fed a standard diet as a negative control group, and the other group was fed a high\u2010fat diet (HFD) for 12\u2009weeks. Then, obese rats were randomly divided into four groups based on the following treatments: (i) a HFD only, (ii) a high\u2010fat diet supplemented with lutein (HFD\u2009+\u2009Lu), (iii) a high\u2010fat diet plus physical exercise (HFD\u2009+\u2009PE), (iv) a high\u2010fat diet plus a combination of lutein and physical exercise (HFD\u2009+\u2009Lu\u2009+\u2009PE) for another 5\u2009weeks. By the end of Week 17, all groups went through a behavioral test (Y\u2010maze), and blood samples, visceral and brain tissues were collected for biochemical and histological examinations, respectively. Our results showed that combining Lu and PE significantly reduced blood glucose, lipid profile parameters, leptin, and malondialdehyde (MDA) levels compared with the HFD group (all\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.0001). Furthermore, the HFD\u2009+\u2009Lu\u2009+\u2009PE group exhibited significantly higher levels of high\u2010density lipoprotein (HDL\u2010C), catalase (CAT), and superoxide dismutase (SOD), along with significantly lower levels of interleukin\u20106 (IL\u20106) compared with the HFD group (all\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.0001). Treatments with Lu, PE, and Lu\u2009+\u2009PE significantly enhanced short\u2010term spatial memory performance in the Y\u2010maze (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.001) and attenuated hippocampal histopathological alterations compared with the HFD group. This study demonstrated that combining lutein and physical exercise is an alternate approach for improving brain health and preventing obesity and its complications in rats fed with HFD. Additionally, the combination of Lu and PE had more beneficial effects on the rat's brain than either Lu or PE alone.\n                  <\/jats:p>","DOI":"10.1002\/fsn3.71913","type":"journal-article","created":{"date-parts":[[2026,5,22]],"date-time":"2026-05-22T07:15:26Z","timestamp":1779434126000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Combined Lutein and Exercise Intervention Alleviates Brain Alteration Induced by a High\u2010Fat Diet in Obese Rats"],"prefix":"10.1002","volume":"14","author":[{"given":"Saraa A.","family":"Almutairi","sequence":"first","affiliation":[{"name":"Department of Biochemistry, Faculty of Science King Abdulaziz University  Jeddah Saudi Arabia"},{"name":"Pre\u2010Clinical Research Unit, King Fahd Medical Research Center King Abdulaziz University  Jeddah Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6535-5887","authenticated-orcid":false,"given":"Hanna M.","family":"Alhoraibi","sequence":"additional","affiliation":[{"name":"Department of Biochemistry, Faculty of Science King Abdulaziz University  Jeddah Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,5,22]]},"reference":[{"key":"e_1_2_13_2_1","doi-asserted-by":"publisher","DOI":"10.3390\/antiox10091448"},{"key":"e_1_2_13_3_1","unstructured":"Alatawi M.
