Fuente: WIPO "tomato" A low-salt fasting-mimicking diet (LS-FMD) is provided for promoting kidney regeneration and treating kidney disease. The LS-FMD comprises cyclic dietary interventions that reduce caloric and sodium intake to induce fasting-like metabolic effects while maintaining essential nutrition. In animal models of puromycin-induced nephrosis, LS-FMD cycles restore normal proteinuria levels and improve nephron structure and function relative to untreated controls. The diet activates kidney-specific gene expression programs and promotes a quiescent, non-proliferative state in mature podocytes, supporting renal recovery. In human subjects with chronic kidney disease, administration of fasting-mimicking diet cycles for five days per month over three months reduces proteinuria and improves endothelial function. The invention demonstrates that kidney-specific fasting-mimicking dietary cycles have therapeutic potential for slowing or reversing progressive renal disorders.
