A typical low-protein diet includes fruits, grains, breads, vegetables and small amounts of protein sources, such as meats, dairy products and nuts, according to the National Institutes of Health. A common recommendation is to eat 1 gram of protein per kilogram of body weight per day.
Doctors typically recommend low-protein diets for patients with kidney or liver conditions, notes the National Institutes of Health. Diet specifics vary depending on the patient's exact needs. To avoid excess weight loss, many patients increase their intake of high-carbohydrate foods and fats, including desserts and healthy fats, such as olive oil. Vitamin and mineral supplements are sometimes necessary to replace those typically found in high protein foods.
A quality low-protein diet contains protein from both animal products and vegetable products, recommends the National Kidney Foundation. Small amounts of different types of protein sources, such as meats, fish, cheese, whole grains and dried beans, provide a variety of amino acids to form the complete proteins the body needs to build and repair tissue. Slicing meat thin and adding lots of vegetables to sandwiches is one way to extend protein to make meals more satisfying. Other techniques to extend protein include adding pasta or rice to soups, extra vegetables to kabobs, and using small amounts of strong cheeses for additional flavor.
