Integrated Lifestyle Interventions for Early-Stage Chronic Kidney Disease: A Public Health Framework Combining Renal Nutrition and Therapeutic Yoga

Abstract

Chronic kidney disease (CKD) is prevalent in people worldwide, impacting over 10% of adults, and is a major contributor to cardiovascular morbidity, premature mortality, and health system costs. Pharmacological approaches in the standard of care (so far) are drugs that reduce hemodynamic and metabolic stress on the nephron, with little attention to dietary protein overload, the generation of uremic toxins from the gut, and dysautonomia. This study brings together the published evidence on two non-pharmacological interventions that have recently been proposed for use alongside guideline-based medical therapy in early-stage (Stage 2-3) CKD: the plant-dominant low-protein diet (PLADO) and structured therapeutic yoga. Meta-analyses of controlled trials show that low protein diets (LPDs), especially with plant proteins (PVs), are associated with slower progression of GFR loss, decreased proteinuria, and improved acid-base and mineral parameters, and do not lead to protein-energy wasting, provided they are well managed. Randomized and observational studies on yoga-based interventions for CKD and dialysis populations separately have shown benefits such as blood pressure, heart rate variability, quality of life, and select inflammatory markers, seemingly mediated by vagally mediated autonomic rebalancing. There is a lack of literature testing these two interventions together as a protocol, with adequate power. This paper illustrates the mechanistic framework of the combined renal nutrition therapy and therapeutic yoga approach, critically reviews the current evidence base for each intervention independently, provides comparative analytical syntheses, suggests an integrated approach in delivering the combined therapy, and outlines a public health approach for implementing it in community-based primary care and nephrology clinics.
