A low-protein diet is not suitable for everyone, and it should not be followed for cosmetic reasons.

This diet is suitable only in certain clinical conditions and under the proper supervision of a doctor and a nutritionist. You can follow this diet in cases of improper kidney function, liver disorder, or inborn errors of metabolism.

In this article, you will find everything you need to know about a low-protein diet.

What Is A Low-Protein Diet?

An average healthy individual needs 10-15% (>0.8 g/kg body weight/d) of calories from protein, depending on the activity level (1).

But in a low-protein diet, only about 20-50 g of protein (which is 0.5-0.6 g/kg body weight) per day is allowed, which amounts to4-8% of the daily calorie requirement (2).

Though protein is extremely vital for bodily functions, improving metabolic rates, and maintaining weight, a low-protein diet with a balanced approach can also have a better effect on health conditions if you have any clinical disorders.

Who Should Follow A Low-Protein Diet?

People with certain metabolic disorders like phenylketonuria (PKU), maple syrup urinary disease, homocystinuria, liver disorders, kidney problems, high levels of uric acid, or sensitivity to proteins need to follow a low-protein diet under proper supervision.

Why Is A Low-Protein Diet Important?

A low-protein diet is effective in certain medical conditions rather than to stay healthy. Here are the benefits of a low protein diet:

1. Reduces Load On Kidneys

A low-protein diet is important for giving your kidneys rest and preventing toxic build-up in the body. When your protein intake exceeds the daily requirement, the excess protein is metabolized by the liver to produce urea, which puts a burden on your kidneys (3).

Your kidneys have to work 24/7 to flush out the urea load. Soon, your kidneys get stressed and become unable to metabolize proteins. As a result, urea gets accumulated in the body, leading to toxic results (4).

2. Effective For Inborn Errors Of Protein Metabolism

A low-protein diet slows down the degradation of protein metabolism, which helps to minimize symptoms of phenylketonuria and homocystinuria, genetic disorders associated with improper protein metabolism (5).

3. Improves Longevity

Foods high in protein, especially animal protein, impact protein metabolism and put a burden on your organs.

Studies have found that foods low in protein and amino acids are strongly associated with improved longevity and metabolic health and reduction in the prevalence rates of cancer, cardiovascular disorders, diabetes (6), (7).

4. Reduces Uric Acid Synthesis

A low-protein diet is important for the treatment of painful gout (inflammatory arthritis caused by excess uric acid synthesis). A study conducted on diabetic rats on a low-protein diet showed a significant reduction in the formation of uric acid (8).

How Much Protein Should Be Taken In A Low Protein Diet?

Normally, your body requires about 40-60 g of protein every day (or 0.8 g of protein per kg body weight, depending on activity level). So, if you weigh 60 kgs and do very little to no physical exercise, you will need 48 g of protein per day (9).

In case you are overshooting that limit, you must reduce your protein consumption to 0.5-0.6 g/kg body weight based on the condition of your kidneys and requirement (2). Consult your doctor for any clinical conditions.

List Of Low-Protein Foods

The bottom line is a low-protein diet is to avoid consuming high-protein sources and have foods that have low-protein content. What are they? Here’s a list of foods to eat and avoid on a low-protein diet.

Foods To Eat

You must consume foods that are low in protein and have good nutritional value. Here’s the list:

Low-Protein Foods

You can follow this sample diet plan and the tips listed in the next section to eat normally and without feeling deprived.

How To Easily Integrate A Low-Protein Diet Into Your Routine

Initially, going on a low-protein diet may seem like a drastic change. But if you know how to tweak your diet plan, it will only get easier. Here’s what you can do.

  • Consume thin slices of meat – this cuts down the protein content.
  • Consider the veggies in your salad as the main dish; the small amount of meat can be the high-protein source.
  • Mostly use non-dairy products.
  • Decrease the meat when you make a casserole.
  • Consume vegetable lasagna.
  • While making wraps and sandwiches, avoid using shrimps and big chunks of meat.

So, it is not that difficult. You just need to check your daily protein intake. You can see in the above diet chart that the total calorie count is lower than that of your regular diet. That’s because when you eliminate a huge portion of protein, the calories take a nosedive. However, you must counteract this problem with the help of calorie boosters. What are they? Find out in the next section.

Calorie Boosters

These are foods that will help you maintain a healthy weight. Here’s what you can eat:

  • Fats – Consume olive oil, mayonnaise, and rice bran oil.
  • Sugar – Add sugar to your diet in the form of jellies, jelly beans, jam, jelly, syrups, gummies, and hard candy.
  • Frozen/Canned Foods – Canned or frozen fruits and veggies are high in calories and can act as calorie boosters when you are on a low-protein diet.

Using these foods will not drastically drop the number of calories you consume, thereby protecting you from weak immunity and fatigue. Now, let’s talk about the most exciting part. Scroll down to find out what it is.

Risks Associated With A Low-Protein Diet

  • Following a low-protein diet on a continuous basis affects the vital functions of cells, such as wound healing and immune response (10).
  • A low-protein diet can lead to muscle loss (10).
  • Finally, this diet is low in iron, calcium, thiamine (vitamin B1), riboflavin (vitamin B2), and niacin (vitamin B3) – and hence, you would need nutritional supplements to sustain normal body functions. But, speak to your doctor before taking any supplements.
  • Increases the risk of infections (11).
  • It can harm the heart if sugar and fat sources are not monitored.
  • May lead to tooth decay.
  • The low-protein diet reduces serum albumin levels, which causes edema (accumulation of water in extremities) (11).

You must talk to your doctor before you start a low-protein diet. Also, take the following precautions.

Precautions To Be Taken On A Low-Protein Diet

  • A low-protein diet should be followed under strict medical guidance from a dietitian who is familiar with liver and kidney diseases.
  • The diet should be designed in a way to meet the nutritional needs of the dieter and cut down the workload on the kidneys.
  • The diet should not eliminate protein-rich foods like eggs, meat, and cheese.

Conclusion

A low-protein diet is great for people who have clinical conditions that call for a reduction in protein intake. Consult your doctor and nutritionist to analyze the problem and devise a customized diet plan with low protein.
