Protein is an essential macronutrient that supports several core body functions, including building enzymes that help power chemical reactions, supporting immune function, and aiding in the maintenance and repair of hair, skin, muscles, and bones. The amount of protein you need depends on several factors, including your age, sex, and level of physical activity. For example, adult males should get at least 56 grams of protein per day, while adult females should get at least 46 grams. People who exercise regularly have higher protein requirements, ranging from 1.1 to 1.7 grams per kilogram of body weight. While a high-protein diet can have health benefits, it is important to maintain adequate intake of other nutrients and choose healthy sources of protein such as low-fat dairy, fish, nuts, beans, lean chicken, and turkey.

What You'll Learn
Recommended daily protein intake for adult males
Protein is an essential macronutrient that supports several core body functions, including building enzymes that help power thousands of chemical reactions in the body. It also helps the body maintain and repair hair, skin, muscles, and bones. Dietary protein also provides amino acids, which are the building blocks of protein. There are 20 amino acids, nine of which are essential to obtain from food because the body does not produce them. These amino acids are integral to a wide range of bodily processes.
The amount of protein you need every day depends on several factors, such as your age, sex, and physical activity level. The Recommended Dietary Allowance (RDA) for protein for an average sedentary adult is 0.8 grams per kilogram of body weight, or 0.36 grams per pound. For example, a person who weighs 75 kilograms (165 pounds) should consume 60 grams of protein per day. This is the minimum amount of protein required to prevent nutrient deficiencies and muscle loss in most healthy individuals.
For adult males, the Dietary Guidelines for Americans 2020–2025 recommend a minimum of 56 grams of protein daily. However, this amount may vary depending on individual factors such as age, physical activity level, and overall health goals. For instance, if you are over 50, you should increase your protein intake to one gram per kilogram of body weight to maintain muscle mass, which declines with age. If you are trying to gain muscle mass, a higher-protein diet can help support muscle repair and growth.
To determine your target daily protein intake, you can multiply your weight in pounds by 0.36, or use an online calculator. It is important to note that your daily protein need is not a fixed number and may fluctuate depending on your level of physical activity, age, and overall health.
If you are considering a high-protein diet, it is important to consult with a healthcare professional or registered dietitian to ensure it is safe and appropriate for your individual needs. A high-protein diet can be beneficial for weight loss, muscle building, and improving overall health, but it should be well-balanced and include a variety of protein sources such as meat, dairy products, nuts, vegetables, and grains.

Health benefits of a high-protein diet
The Recommended Dietary Allowance (RDA) for protein for an average adult is 0.8 grams per kilogram of body weight, or 0.36 grams per pound. This amounts to 56 grams of protein for adult males and 46 grams for adult females. However, this is the minimum amount required to prevent nutrient deficiencies and muscle loss. Research suggests that eating more protein than the RDA may promote weight loss and overall health.
A high-protein diet can help with weight loss because protein may keep you satiated for longer and boost your metabolism. It can also help you build muscle mass, strengthen your bones, and help your body heal after injuries.
Protein-rich foods include meat, dairy products, nuts, some vegetables, and certain grains and beans. Try to eat a variety of protein-rich foods to ensure you are meeting your daily protein needs as well as getting the vitamins, minerals, and other nutrients needed for optimal health.
However, it is important to note that a high-protein diet that is predominantly made up of red meat or processed meat is linked to higher risks of cardiovascular disease and diabetes. For optimal health and nutrition, it is recommended to emphasize plant-based protein and protein from a variety of sources.

High-protein foods
The amount of protein you need in your diet depends on several factors, such as your age, sex, and physical activity level. According to the Dietary Guidelines for Americans 2020–2025, adult males should get at least 56 grams of protein per day, while adult females should get at least 46 grams. This amount of protein can be obtained from various food sources, including both animal and plant-based options.
If you are looking to increase your protein intake, it is recommended to choose high-quality protein sources and balance your intake with healthy fats and carbohydrates. Here are some examples of high-protein foods:
Animal-Based Sources:
- Meat: Lean meats such as chicken, turkey, beef, and pork are excellent sources of high-quality protein and also provide important nutrients like iron and zinc. It is recommended to choose leaner cuts of meat to avoid consuming excessive amounts of saturated fat and sodium.
- Dairy: Dairy products like milk, cheese, yogurt, and cottage cheese are rich in protein. Greek yogurt, in particular, is a great option as it is high in protein and other nutrients like calcium, vitamins, and minerals.
- Eggs: Whole eggs provide high-quality protein and essential vitamins, minerals, healthy fats, and antioxidants. They are also versatile and can be prepared in a variety of ways.
Plant-Based Sources:
- Legumes: Lentils, chickpeas, black beans, kidney beans, and soybeans are excellent sources of plant-based protein. They also provide fiber, folate, potassium, iron, and zinc.
- Nuts and Seeds: Almonds, peanuts, hazelnuts, walnuts, chia seeds, pumpkin seeds, and sunflower seeds are rich in plant-based protein and provide healthy fats, vitamins, and minerals. Peanut butter is also a good option.
- Soy Products: Tofu, tempeh, and soy milk are good sources of protein, especially for vegetarians and vegans. They also provide other essential amino acids.
- Grains: Quinoa, oats, and spirulina are plant-based sources of protein that can be easily incorporated into meals.
It is important to note that while a high-protein diet can have health benefits, it should be well-balanced and include a variety of nutrient sources. Additionally, if you have any specific dietary restrictions or health concerns, it is always best to consult with a healthcare professional or registered dietitian to determine the right diet plan for your individual needs.

Risks of a high-protein diet
For adult males, the recommended dietary allowance (RDA) for protein is 56 grams per day. This amount is the minimum required to prevent nutrient deficiencies and muscle loss. Research suggests that eating more than this amount may promote weight loss and improve overall health.
However, consuming too much protein can lead to several risks and adverse effects:
Risk of Kidney Stones: People who eat very high-protein diets have a higher risk of developing kidney stones. This is because the kidneys help filter waste products from the body, including waste products from protein metabolism. In people with impaired kidney function, a high-protein diet may strain the kidneys, leading to potential damage.
Cardiovascular Disease and Diabetes: Research has consistently linked both unprocessed and processed red meat to higher risks of cardiovascular disease and diabetes. A high-protein diet that contains large amounts of red meat and higher amounts of saturated fat might increase the risk of these conditions.
Blood Vessel Disorders: Chronic protein overconsumption can increase the risk of blood vessel disorders.
Liver and Kidney Issues: Excessive protein intake has been associated with an increased risk of liver and kidney problems. This includes conditions such as kidney stones and potential damage to the kidneys, as mentioned earlier.
Seizures: High protein consumption has been linked to an increased risk of seizures in some individuals.
Nutrient Deficiencies: A diet that prioritizes protein may lead to deficiencies in other essential nutrients, such as vitamins and minerals. It is important to maintain a balanced diet and ensure adequate intake of all necessary nutrients.
Digestive System Issues: Consuming too much protein can lead to problems involving the digestive system. This may include issues such as constipation, diarrhoea, or other gastrointestinal discomforts.
It is important to note that the risks associated with a high-protein diet may vary depending on individual factors, such as age, sex, physical activity level, and overall health. It is always advisable to consult with a healthcare professional or registered dietitian before making significant changes to your diet. They can help determine the appropriate amount of protein intake based on your specific needs and health status.

Weight loss and muscle gain
Protein is one of the three core macronutrients, along with carbohydrates and fats. It is a building block in the body, essential for growth, development, and the repair and building of cells and tissue such as muscle. It also plays a key role in body processes such as blood clotting, fluid balance, and the immune response.
The amount of protein you need each day depends on several factors, including your age, sex, and level of physical activity. The Recommended Dietary Allowance (RDA) of protein is 0.8 g per kilogram of body weight (g/kg/bw), or 0.36 g per pound of body weight (g/lbs/bw). This is the minimum amount to prevent nutrient deficiencies and muscle loss. However, research suggests that eating more than the RDA may promote weight loss and overall health. For example, a 2017 study found that participants who ate a high-protein diet of 1.34 g/kg/bw (0.6 g/lbs/bw) lost significantly more weight than those following RDA requirements.
For adult males, it is recommended to get at least 56 grams of protein per day, while adult females should aim for at least 46 grams. Eating a high-protein diet can help with weight loss by keeping you satiated for longer, boosting your metabolism, and reducing the buildup of harmful fats in your body. It can also help prevent muscle loss during weight loss, as protein is essential for building and repairing muscle.
To get enough protein in your diet, include a variety of protein-rich foods from both animal and plant-based sources. Animal sources such as meat, eggs, and dairy provide complete proteins, meaning they contain all the essential amino acids. Plant-based sources such as soy, quinoa, and certain grains and beans are also good options, but most do not contain all the essential amino acids, so it is important to vary your plant-based protein sources.
While a high-protein diet can be beneficial for weight loss and muscle gain, there are some potential risks to consider. High-protein diets that limit carbohydrates can lead to inadequate intake of fiber and other nutrients, causing side effects such as bad breath, headaches, and constipation. They may also increase the risk of heart disease, especially if consuming unlean meat with high saturated fat content. Additionally, high-protein diets can be problematic for individuals with pre-existing kidney conditions and may increase the risk of kidney stones.
If you are considering a high-protein diet for weight loss and muscle gain, it is important to speak with a healthcare professional or registered dietitian to ensure it is safe and appropriate for your individual needs. They can help you determine the right amount of protein for your goals and develop a nutrition plan that is balanced and sustainable.
