Reducing dietary sodium has the potential to benefit patients with chronic kidney disease on hemodialysis (HD). This study was aimed to evaluate the effects of dietary counseling on sodium restriction and its relationship with clinical, dietary, and quality of life parameters in patients on HD treatment. This study was designed as a randomized clinical trial. The study included 87 patients on HD, divided into intervention (n = 47) and control (n = 40) groups. Anthropometric, clinical, sodium intake, and quality of life data were evaluated in both groups at four-time points: baseline (T0), 90 days (T3), 180 days (T6), and 365 days (T12). The intervention group received dietary counseling at the beginning and throughout the study. There were no between-group differences regarding anthropometric, clinical, and quality of life data at any of the time points. The mean age was 59 ± 14 years, and most of the patients were men (61%) and had hypertension (90%). Total sodium (g) and processed meat (mg sodium) intake significantly decreased in both groups [intervention: T0 = 3.5 (2.3–4.7); T12 = 2.0 (0.7–2.5); P
