Low Protein Diet


Low-protein diets are most commonly used by individuals with severe liver or kidney disease. Patients with these conditions must limit their protein intake as excess amounts can build up in the body, worsening their condition. Protein contains nitrogen which, when metabolized, leaves the body in urine. If the person has trouble excreting urine, like many patients with a compromised liver or kidneys, the waste from nitrogen builds up in the bloodstream causing nausea, headaches, fatigue, and further damage to the liver and kidneys.


The purpose of the low protein diet is to reduce stress on the liver and kidneys. Foods high in protein like milk, eggs, and meat should be substituted for more complex carbohydrates which can provide extra calories for energy to compensate for those not gained from protein-rich food. Working with a physician, patients can find an acceptable level of protein their body can tolerate. Protein should never be completely removed from the diet.
