What might be a recommended dietary approach for patients suffering from muscle wasting due to CKD?

For patients suffering from muscle wasting due to chronic kidney disease (CKD), focusing on high-protein diets is often recommended. This is because individuals with CKD may experience protein-energy malnutrition, especially in the later stages of the disease. Supplementing dietary protein can help mitigate muscle loss and improve overall nutritional status.

High-quality protein sources are important in these situations, as they provide essential amino acids necessary for muscle repair and synthesis. The aim is not merely to increase protein, but to ensure that the protein consumed is of high biological value, which means it contains all the essential amino acids in proportions suitable for bodily needs.

Appropriate protein intake is crucial because while CKD limits overall protein consumption to manage uremic symptoms, strategically increasing protein in the context of preventing muscle wasting and during dialysis can be beneficial. It's essential to tailor this approach to the individual’s stage of CKD, protein needs, and kidney function status.

This dietary strategy stands in contrast to the other options presented, which do not adequately address the need for protein during CKD—either by potentially leading to deficiencies (like reducing caloric intake) or not supporting muscle preservation (like simply increasing carbohydrates or fats).
