ABSTRACT

Metabolic health is a dynamic equilibrium influenced by diet and lifestyle. This review synthesizes evidence on how specific dietary patterns and bioactive nutrients modulate metabolic disorders. Diets like the Mediterranean and DASH plans consistently improve cardiometabolic markers: a Mediterranean diet can halve metabolic syndrome prevalence (~52% reduction) in as little as 6 months, while the DASH diet typically lowers systolic blood pressure by ~5-7 mmHg and modestly improves lipid profiles (LDL-C by ~3-5 mg/dL). Plant-based diets (vegetarian/vegan) are associated with lower BMI, improved insulin sensitivity, and reduced inflammation. Ketogenic diets induce rapid weight loss (~12% body weight vs. 4% on control diets) and improve glycemic control (reducing HbA1c and triglycerides), though long-term effects (elevated LDL) warrant caution. Bioactive compounds present in these diets play critical roles: polyphenols improve insulin signaling and reduce oxidative stress (resveratrol supplementation reduced HOMA-IR by ~0.5 units and fasting glucose by ~0.3 mmol/L); omega-3 fatty acids (fish oil) reduce triglycerides by ~25-30% and inflammation; and probiotic interventions modestly enhance glycemic control (lowering HOMA-IR and HbA1c) and gut health. Personalized nutrition approaches, which account for genetic and microbiome differences, are emerging to maximize these benefits. In conclusion, evidence-based dietary strategies rich in fiber, unsaturated fats, and phytochemicals can substantially improve metabolic health outcomes, underscoring the potential of tailored nutrition in preventing and managing obesity-related metabolic disorders.
