Low Protein Diet: Benefits,Risks And More

A low-protein diet could be beneficial in providing health benefits. It may be effective in reducing blood pressure, kidney issues, and much more.

It could also support reducing weight though there are potential risks associated with a low-protein diet. Here we will be looking at all about the low-protein diet, its benefits, risks, and much more.

Low Protein Diet


What Is Low Protein Diet?

A low-protein diet involves consuming fewer high-protein foods overall. The majority of the time, protein is found in animal foods. Some plant-based foods do, however, contain protein.

This diet might be necessary for you to follow if you suffer from gout, liver, kidney, or both conditions. Your body might be unable to process additional protein if you have these conditions.

One or more of the proteins’ functions include the following:

  • Development and upkeep of tissues
  • Production of enzymes and hormones
  • Give the bones, tendons, ligaments, and skin their supporting structure.
  • Maintains the proper fluid and acid-base balance in the cell.
  • Improves immune function
  • Carries and holds nutrients

Benefits Of Low Protein Diet

For people with kidney disease, a low-protein diet has been shown to have several advantages.

According to a study, a low-protein diet could lower the amount of protein in the urine, enhance lipid and cholesterol levels, and even help people with diabetes and early-stage CKD maintain better glucose control.

Urea is a significant problem for a lot of kidney disease patients. A low-protein diet lowers the level of urea created by the metabolism of proteins.

As a result, the blood urea nitrogen (BUN) levels could be reduced, aiding in the kidneys’ protection. Furthermore, it has been demonstrated that a low-protein diet could lower blood pressure when combined with a low-sodium diet.

Along with these advantages

  • Support of kidney function
  • Protein levels in urine are lower
  • Reduced possibility of metabolic acidosis
  • Decrease in oxidative stress
  • Decreased insulin resistance
  • Reduced or under-control blood pressure
  • Much fewer uremic toxins
  • Enhanced phosphorus management

Risks Of Low Protein Diet

There may be potential negative consequences from a low-protein diet if it is not closely monitored by medical professionals. There is a chance of not obtaining enough calories when protein intake is reduced.

As a result, weight loss may occur accidentally. Muscle breakdown may result from weight loss that occurs too quickly or dangerously.

Increased inflammation represents another risk. A lack of calories consumed or muscle breakdown may be the cause of this. Additionally, poor blood sugar regulation may result from this inflammation.

Avoiding or severely limiting animal meats is typically necessary for a low-protein diet. Anemia, one of the early indications as well as symptoms of kidney disease, may result from a low-protein diet as a result.

Foods To Eat

There are a few aspects you should be aware of if you’re considering beginning a low-protein diet. To start, pick foods that are rich in other nutrients but low in protein.

Your body requires a certain amount of protein, so you must ensure that you are consuming enough of it. And finally, you must be aware of any negative effects that a low-protein diet may have. Here is a list of foods low in protein to get you started:

  1. Fruits


    Apples are regarded as a fruit with little protein. This is due to the lack of lysine, an amino acid required by the body to produce protein.

    Because meats contain a lot of lysines, a diet that only contains apples as a source of protein is probably lacking in protein.

    They also contain a lot of fiber, which could help regulate digestion. The vitamins and minerals, potassium, and vitamin C are also abundant in apples.


    Finding additional sources of energy is necessary when following a low-protein diet, and bananas may be able to help.

    They are a good option for those looking to lose weight because they are low in calories, fat, and fattening ingredients.


    Due to their low protein content, pears are frequently included in low-protein diets. One gram of protein is found in a typical pear, making them a good option for those looking to consume less protein.

  2. Vegetables


    Because tomatoes contain non-protein nitrogen, they are regarded as low-protein food. All plants contain non-protein nitrogen, but tomatoes have a higher concentration than the majority of other plants.

    This substance is not a source of protein because the body does not break it down and uses it for protein synthesis.


    Considering how little methionine it contains, asparagus is regarded as a low-protein food. Our bodies require the amino acid methionine to create proteins.

    It is crucial to consume items that are rich in methionine, like meat, fish, and eggs, as we could only obtain it from our diets.


    Broccoli is regarded as a low-protein food for several reasons. As opposed to other foods, it has a very low protein content.

    Broccoli also has a lot of fiber, which is good for digestion and weight loss. Broccoli has very few calories and fat.

  3. Grains


    Rice mainly consists of carbohydrates; it contains very little protein. The essential amino acids, which serve as the foundation for proteins, are not abundant in them. In high-protein diets like the Atkins Diet, rice is frequently excluded as a result.


    Oats may make people feel fuller longer and may even aid in weight loss. Oats are also a good source of important vitamins and minerals like iron and magnesium.

    Due to the potential risk of nutrient deficiencies, this makes them a perfect food for those following a low-protein diet.


    Since bread contains less protein than other foods, it is regarded as a low-protein diet. Typically made with whole grains, these bread are high in fiber.

    They could make you feel more satisfied and even lower your cholesterol. Decide to buy whole-grain bread if you’re looking for a nutritious way to include bread in your diet.

  4. Healthy Fats


    Avocados are regarded as a low-protein food for many different reasons. They also contain a lot of good fats, which may keep you feeling full and satisfied.

    Avocados also contain only about 4 grams of protein per fruit, which is not very much. A low-protein diet enthusiast should consider avocados for all of these reasons.

    Olive Oil

    Olive oil is frequently used in low-protein diets because it could aid in the promotion of satiety. As a result, it may help you feel satisfied for a longer period, which may be beneficial if you’re trying to manage your hunger or lose weight.

    The ability of olive oil to control blood sugar levels makes it beneficial for diabetics.

    Coconut Oil

    Due to the presence of a specific type of saturated fat that is absent from other oils, coconut oil is considered to be advantageous for a low-protein diet.

    Lauric acid is a type of fat that is processed differently from other saturated fats. Lauric acid is a good choice for individuals on a low-protein diet because it is believed to be simpler for the body to digest and use for energy.

When Should You Consume A Low-Protein Diet?

Protein must make up 10% to 15% of an average person’s daily calorie intake.

However, if you experience any of the following medical conditions, you should adhere to a diet that limits your protein intake to 4% to 8% of your daily caloric intake.

A diet low in protein lowers the strain that improper amino acid digestion may put on your organs.

  1.  Lessen The Burden On The Kidneys

    To give your kidneys a break and avoid toxicity build-up in the body, you should eat a low-protein diet. When you consume more protein than your body needs each day, the liver breaks down the extra protein to make urea, which strains your kidneys.

    To remove the urea load, your kidneys must function nonstop. Your kidneys begin to experience stress and eventually lose their ability to metabolize proteins.

    Because of this, the body develops toxic effects from an accumulation of urea.

  2. Effective For Inherited Protein Metabolism Issues

    Inadequate protein metabolism is linked to the genetic disorders phenylketonuria and homocystinuria, and a low-protein diet decreases the rate of protein degradation, which also helps to reduce symptoms of these conditions.

  3. Enhances Longevity

    Protein-rich foods, particularly those derived from animals, affect how your body processes proteins and put stress on your organs.

    According to a study, eating food products low in protein as well as amino acids is significantly linked to a longer life expectancy, better metabolic health, and a drop in the prevalence of diabetes, cancer, and cardiovascular diseases.

  4.  It Minimizes The Synthesis Of Uric Acid

    The management of excruciating gout requires a low-protein diet. According to a study done on diabetic rats fed a low-protein diet, uric acid production was significantly decreased.

Safety Measures For Low-Protein Diets

A dietitian with experience in treating liver and kidney conditions should be consulted before beginning a low-protein diet.

The nutrition should indeed be planned to satisfy the dieter’s dietary requirements and lessen the strain on the kidneys. Foods high in protein, such as eggs, meat, and cheese, should not be restricted in the diet

Final Thoughts

People with kidney issues, diabetes, and some genetic disorders could benefit significantly from a low-protein diet, but it is not advised for those who are looking to build muscle.

It could also be helpful for those who want to lose weight. The advantages to your health outweigh the difficulty of adhering to a low-protein diet.

But before starting this diet, it’s wise to speak with a doctor because a low-protein diet might not be suitable for everyone.
