The present review delves into the ways in which fitness routines and evidence-based food interventions enhance physical performance, prevent disease, and promote general well-being. The state of the art research on nutritional timing, plant-based and Mediterranean diets, macronutrient and micronutrient balance, and personalised nutrition is reviewed, along with potential future possibilities for incorporating these strategies into health and fitness regimens. 1. INTRODUCTION In order to maintain good health, avoid sickness, and increase physical fitness, nutrition is crucial. In order to maximise fitness results and improve general health, there is a growing emphasis on incorporating customised, evidence-based dietary methods as a result of developments in dietetics and nutritional science. The relationship between nutrition, dietetics, and fitness is examined in this review, which also outlines the best practices and their supporting scientific evidence. It has been demonstrated that combining customised diet and exercise regimens improves weight control, lowers the risk of chronic illnesses, and improves athletic performance (Martín-Rodríguez, A. et al., 2024). For this reason, it is essential for practitioners as well as individuals looking to improve health outcomes to understand the evidence-based practices in food, nutrition, and fitness. [1] METHODOLOGIES This review study uses a methodical technique to investigate dietetics, food, nutrition, and health fitness integrative approaches. A number of crucial processes make up the methodology employed in this review, including the literature search, selection criteria, data extraction, and information synthesis. The comprehensive techniques utilised at each step are listed below: 1.1 Literature Search To find pertinent research and reviews, a thorough search of the scientific literature was done. The search was conducted using databases like PubMed, Google Scholar, Web of Science, and Scopus. Terms including “nutrition,” “diet,” “health fitness,” “dietetics,” “integrative nutrition,” “individualised nutrition,” “mediterranean diet,” “plant-based diets,” “sports nutrition,” and “physical performance” were among the combinations of keywords and phrases used. Only articles published between 2000 and 2023 were included in the search, with peer-reviewed journals being given preference. 1.2 Selection Criteria Studying integrative methods to dietetics, food, and nutrition and their effects on fitness and health are the inclusion criteria. Studies that place a strong emphasis on evidence-based eating habits. Articles that offer information on how diet affects overall health, disease prevention, and physical fitness. Cohort studies, systematic reviews, randomised controlled trials (RCTs), meta-analyses, and clinical trials. Articles that don’t meet the requirements for peer review or don’t offer enough proof to support their assertions are excluded. Studies with inadequate data or ambiguous methodology. Studies that are limited to specialised food changes and have little bearing on overall fitness and health.
