A low-protein diet is a dietary approach that restricts the amount of protein intake. This type of diet is sometimes recommended for individuals with kidney diseases and other medical conditions. However, there are other terms that can be used to describe a low-protein diet, such as reduced-protein diet, protein-controlled diet, and protein-modified diet. These synonyms emphasize the same concept of limiting protein consumption to improve overall health. It is important to speak with a healthcare professional or a registered dietitian to determine the best approach to a low-protein diet and ensure that all nutrient needs are being met.
