Obesity and chronic kidney disease (CKD) frequently coexist and mutually exacerbate metabolic, inflammatory, and hemodynamic disturbances that accelerate kidney function decline. Dietary therapy is central to weight management in CKD, yet traditional nutrient-restriction strategies may compromise diet quality and adherence. This review aims to evaluate the suitability of three major dietary patterns, the Mediterranean diet, plant-forward diets, and low-carbohydrate/ketogenic diets, for managing obesity in individuals with CKD.
