It was particularly meaningful that the authors focused not on adding another medication, but on nutritional management, an area where patients can actively participate in their care.  \nPatients with CKD often take multiple medications and maybe reluctant to add yet another drug. In contrast, dietary modification can be more acceptable because it allows individuals to feel involved in their treatment decisions. At the same time, dietary restrictions directly affect daily life, and therefore quality of life (QOL) concerns are just as important as adherence. Historically, strict protein restriction has suffered from poor adherence and significant lifestyle burden [1] . In this context, the moderate restriction examined in this study (0.6–0.7 g/kg/day), combined with personalized support and a weekly unrestricted meal, seems far more feasible. The high acceptance (96%) and moderate adherence (about 60%) underscore the practicality of such an approach.  \nSeveral aspects of the study population are noteworthy. The participants had relatively high-risk characteristics, including a median proteinuria of 0.94 g per 24 hours, hypertension in nearly 87%, and diabetes in 43%, yet the use of renin–angiotensin–  \naldosterone system (RAAS) inhibitors, a cornerstone of CKD treatment, was unexpectedly low at ∼30%. This finding could not be explained by hyperkalemia or metabolic acidosis, and the use of potassium binders was also limited. Because CKD progresses slowly, it is critically important to optimize fundamental therapeutic measures before patients reach advanced stages. These measures include adequate blood pressure control and appropriate use of RAAS inhibitors, and early intervention is expected to maximize the potential for slowing kidney function decline.  \nIn this study, conducted between 2021 and 2023, the mean systolic blood pressure at enrollment was well above the KDIGO 2021 recommended target of \u003C120 mmHg [2], suggesting that treatment may not have been fully optimized before nephrology referral. In addition, many older patients may have found it difficult to reach lower blood pressure targets due to medication tolerability issues. Differences in recommended blood pressure targets for older adults across international guidelines may also help explain why blood pressure tended to remain higher in this cohort. Furthermore, the low use of RAAS inhibitors may have contributed to suboptimal blood pressure control. At the last visit, blood pressure was still not sufficiently controlled, and discontinuation of RAAS inhibitors was relatively common. Given these circumstances, the effects ofthe LPD should be interpreted in the context of suboptimal baseline management. Even so,  \nReceived: 5.12.2025; accepted: 5.12.2025  \n© The Author(s) 2025 .
