A low-protein diet is often recommended for people with kidney-related illnesses or liver disease. This is because healthy kidneys remove extra fluid and waste from the blood, but when they are damaged, they may leak protein into the urine. A low-protein diet can reduce stress on the kidneys and prevent the buildup of urea in the bloodstream. For those without kidney problems, a low-protein diet may still provide some benefits, such as reducing the risk of cognitive decline. To reduce protein in your diet, it is recommended to replace some meat, eggs, and cheese with vegetables, grains, and low-value proteins like rice.

What You'll Learn
Evaluate your normal diet
Evaluating your normal diet is an important step in reducing protein intake. Here are some key considerations:
Identify Protein Sources and Values
Firstly, you should identify the main sources of protein in your diet and their respective protein contents. This awareness will enable you to analyse your diet and understand where and how you consume protein. Meat, poultry, seafood, eggs, dairy, beans, nuts, and soy products are all significant sources of protein. Knowing the protein content of these foods will help you make informed choices about reducing your intake.
Consider Your Health and Condition
If you have a health condition, particularly related to your liver or kidneys, it is crucial to consult a doctor or dietitian before making any dietary changes. They can advise you on finding the right balance and ensuring your diet meets your nutritional needs. For example, if you have liver disease or impaired kidney function, a low-protein diet may be recommended to reduce the workload on these organs and prevent a buildup of urea in the bloodstream.
Evaluate Your Dietary Habits
Take a close look at your dietary habits and patterns. Are there specific meals or snacks that are particularly high in protein? Are there any areas where you can easily reduce your protein intake without compromising on nutrition? For instance, you could try having more meat-free days or meals, as meat is a major source of protein. You don't necessarily have to cut it out entirely but rather reorganise your meals so that meat is a smaller side dish instead of the main course.
Understand Recommended Levels
It is important to have a basic understanding of the recommended protein intake levels. The Dietary Guidelines for Americans 2020–2025 recommend that adult females and males consume at least 46 grams and 56 grams of protein daily, respectively. However, these values can vary depending on factors such as age, sex, weight, and physical activity level. For instance, older adults may need higher protein intakes to prevent sarcopenia, the loss of muscle mass associated with ageing.
Analyse Your Meal Composition
When evaluating your diet, consider the composition of your meals. Are proteins accompanying fruits, vegetables, and whole grains, or are they the main focus of the meal? Favouring lower-value proteins over high-value proteins can help lower your overall protein intake while maintaining a balanced diet. For example, adding vegetables to ground meats or eggs can reduce the overall protein content of the dish.

Reduce meat consumption
Reducing meat consumption can be beneficial for both your health and the planet. Eating too much red and processed meat is associated with an increased risk of heart disease, stroke, type 2 diabetes, and certain types of cancer. Additionally, the production of meat, especially beef, lamb, and goat, has a significant impact on our planet's health.
- Gradual reduction: You don't have to completely eliminate meat from your diet. A partial shift away from a meat-centred diet can make a positive impact. Start by reducing the number of meat-based meals you eat per week and gradually increase the number of vegetarian or vegan meals.
- Replace with plant-based options: Opt for plant-based proteins such as beans, lentils, nuts, whole grains, and soy products. These foods provide essential amino acids and can be used to create filling and delicious meals.
- Choose sustainable seafood: If you're reducing meat consumption, seafood can be a great alternative. However, choose sustainable options that are ethically sourced. The Monterey Bay Aquarium's Seafood Watch program can help you make informed choices about sustainable seafood.
- Explore alternative sources of protein: Poultry, low-fat dairy products, and eggs are excellent sources of protein that can be incorporated into your diet.
- Plan your meals: Plan your meals in advance to ensure you're getting a balanced diet. This will help you create a variety of tasty meals that are not centred around meat.
- Meat-free challenges: Participate in meat-free challenges like Meatless Mondays or Veganuary. These initiatives can help you develop new habits and explore meat-free alternatives.
- Support sustainable agriculture: When purchasing meat, choose locally sourced, ethically raised, and sustainable options. This reduces the environmental impact of meat production and supports farmers who are adopting sustainable practices.

Eat more grains, fruits, and vegetables
Eating more grains, fruits, and vegetables is a great way to reduce protein in your diet. Whole grains, in particular, are a healthy option as they contain all the important parts of the entire grain seed, including the bran, germ, and endosperm, in their original proportions. This means they are packed with fiber, protein, and other nutrients, and have a chewier texture and toasted, nutty flavor.
You can easily incorporate whole grains into your diet by choosing whole grain bread, pasta, crackers, and tortillas over their refined counterparts. You can also substitute a portion of white or refined flour with whole-grain flour when baking. Some healthy whole grain options include wheat berries, barley, spelt, farro, and brown rice.
Fruits and vegetables are also an important part of a balanced diet. They are rich in vitamins, minerals, and other nutrients, and can help prevent illnesses such as heart disease and cancer. Aim to fill half your plate with fruits and veggies, which comes to about 2 1/2 cups of vegetables and 2 cups of fruit each day. Include a variety of colorful fruits and vegetables in your diet to get the widest range of nutrients. You can also try adding fruit to your cereal or yogurt, or simply keep washed and ready-to-eat fruit within easy reach to grab when you're on the go.

Consult a doctor or dietitian
It is important to consult a doctor or dietitian before reducing your protein intake to below 10% of your daily calorie intake. This is because protein is an essential nutrient, and even people on a low-protein diet need to consume a certain amount to stay healthy. A low-protein diet requires careful planning; otherwise, it could lead to nutritional deficiencies and other health issues, including muscle loss and poor immune function.
Doctors and dietitians can help determine if a low-protein diet is a good option for you and can provide guidance to ensure your diet is still healthy and well-rounded. They can also advise on how much protein to aim for based on your individual circumstances, such as your weight, age, and any health conditions. For example, older adults may need extra protein due to muscle wastage associated with aging.
A low-protein diet typically restricts protein consumption to 4–8% of daily calories, which is around 20–50 grams of protein per day. This is in contrast to the average person's recommended protein intake of at least 10–15% of their daily calories. A doctor or dietitian can help you assess your protein intake and recommend dietary changes to ensure you are getting adequate nutrition.
Additionally, a doctor may recommend a low-protein diet for certain health conditions. For example, people with kidney-related health issues, such as chronic kidney disease (CKD), may need to follow a low-protein diet to reduce stress on their kidneys and prevent the buildup of urea in the bloodstream. Similarly, a low-protein diet can benefit those with liver disease, as it eases the workload of the liver and helps improve protein metabolism.
In summary, consulting a doctor or dietitian before reducing your protein intake is crucial to ensure you are getting enough of this essential nutrient and to determine if a low-protein diet is suitable for your individual needs and health circumstances.

Add vegetables to eggs or ground meats
Adding vegetables to eggs or ground meats is a great way to reduce protein in your diet, especially if you're a frequent meat eater. Here are some ideas to get you started:
Eggs and Vegetables
Eggs are a versatile food that can be paired with a variety of vegetables to create nutritious and tasty meals. Here are some suggestions:
- Spinach and Eggs: Spinach is a nutritious leafy green that pairs well with eggs. You can sauté the spinach and add it to scrambled eggs or create a frittata or quiche with eggs, cream, and cheese.
- Tomatoes and Eggs: A classic combination, tomatoes can be diced and mixed into scrambled eggs or omelets for a colourful and flavourful dish. You can also try the Turkish dish Menemen, which combines scrambled eggs with green peppers, tomatoes, and onions.
- Potatoes and Eggs: Potatoes and eggs are a perfect duo. Try a Spanish tortilla by combining fried potato slices and onions with whisked eggs, cooked on the stovetop and finished in the oven. You can also create a hash and eggs dish by scooping out a round space in a potato-based dish and baking an egg directly into it.
- Mushrooms and Eggs: Sautéed mushrooms are a classic omelet filling. Thinly slice or finely dice the mushrooms and fry them before mixing them into your eggs.
Ground Meat and Vegetable Alternatives
If you're looking to reduce the amount of ground meat in your diet, there are several vegetable alternatives that can be used in similar ways:
- Mushrooms: Portobello mushrooms, in particular, have a meaty texture and savoury flavour that make them a great substitute for ground beef in dishes like pasta or burgers.
- Legumes: Cooked legumes such as beans, chickpeas, and lentils can be used as a meat substitute in burgers, chillies, and stuffed peppers. They are high in protein, fibre, and other essential nutrients.
- Cauliflower: This versatile vegetable can be used as a low-carb substitute for rice or pizza crust, or even as a meat substitute in main or side dishes.
- Seitan: A plant-based alternative with a high protein content, similar to chicken breast. It can be used in various dishes, such as tacos or zucchini boats.
- Nuts: Nutrient-rich nuts like walnuts and pecans can be ground and used as a meat substitute in dishes like vegan chili or tacos.
Remember, when reducing protein in your diet, it's important to ensure you're still meeting your daily recommended protein intake. The recommended amount is 46 grams for adult females and 56 grams for adult males.
