Abstract

Objectives: This study investigated the effects of calorie restriction supplemented with fish oil (CRF) in middle-aged women with MetS. Design: An open-label, parallel-arm, controlled trial was conduct for 12 weeks. Participants: Seventy-five eligible participants were randomly assigned either calorie restriction (CR) or CRF. Both dietary intervention groups were further divided into two age groups: ≤45 and >45 years. Measurements: The changes in MetS severity, inflammatory status, iron status, and red blood cell fatty acid profile were evaluated. Results: Seventy-one participants completed the trial. Both dietary interventions significantly ameliorated MetS and improved the participants’ inflammatory status. CR significantly increased total iron binding capacity, whereas CRF increased hepcidin levels. Furthermore, CRF significantly increased the n-6/n-3 and arachidonic acid/docosahexaenoic acid ratios. CR and CRF improved the anthropometric and MetS characteristics of early-middle aged women, including body weight, blood glucose levels, triglyceride levels, as well as the scores for the homeostasis model assessment of insulin resistance and quantitative insulin sensitivity cheque index. Conclusion: Our dietary interventions suggest that calorie restriction with fish oil (CRF) shows more effective amelioration on the status of PC and TIBC levels in older middle-aged women (>45 years) than in younger middle-aged women (45 years).
