A diet with low protein is for only some people and not for everyone. This diet is advised for people with certain health conditions.
A low-calorie diet should be followed under a nutritionist and doctor observation. You can follow this diet for a liver disorder, kidney function, and inborn metabolism errors.
What Is A Low-Protein Diet?
Table of Contents
A normal person needs 10-15% (>0.8 g/kg body weight/d) of calories out of the protein, based on their fitness level. But in a low protein diet, only about 20-50 gm of protein (which is 0.5-0.6 g/kg body weight) every day is advised, which amounts to 4-8% of the everyday calorie requirement.
Even though protein is important for body functions, boosting metabolic rates, and balancing weight, a low protein diet with a maintained approach can also have a good effect on health conditions if you are experiencing any clinical problem.
Who Should Start A Low-Protein Diet?
Individuals with certain metabolic issues like phenylketonuria (PKU), homocystinuria, kidney issues, maple syrup urinary illness, liver issues, elevated levels of uric corrosive, or affectability to proteins need to follow a low-protein diet under legitimate oversight.
Why Is A Low-Protein Diet Necessary?
A low protein diet is the best way to cope with medical conditions rather than to stay healthy. Here are the benefits of the low protein diet:
Lower Pressure on Kidneys
The low protein diet is essential for giving rest to kidneys and limiting the toxic accumulation in the body. When the protein consumption exceeds the everyday need, the extra protein gets metabolized by the liver to generate urea, which keeps pressure on kidneys.
The kidneys have to function 24/7 to remove out the urea load. Soon, the kidneys get pressure and become slow to remove extra proteins. As a result, urea build-up in the body and have toxic results. The low protein diet is essential for giving rest to kidneys and limiting the toxic accumulation in the body. When the protein consumption exceeds the everyday need, the extra protein gets metabolized by the liver to generate urea, which keeps pressure on kidneys.
Successful for Inborn Mistakes of Protein Metabolism
A low-protein diet hinders the debasement of protein digestion, which assists with limiting signs of homocystinuria, and phenylketonuria, hereditary issues related to improper protein digestion.
Improves Longevity
Foods with high protein, particularly animal protein, influence protein metabolism, and keep the pressure on organs. According to studies, foods with amino acids and low protein are strongly linked with improved longevity and metabolic health and lower the cancer prevalence rate, diabetes, and cardiovascular disease.
Decreases Uric Acid Synthesis
A low-protein diet is significant for the treatment of severe gout (inflammatory joint inflammation brought about by excess-uric-acid-synthesis). An examination directed at diabetic rats on a low-protein diet indicated a huge decrease in the development of uric acid.
How Much Protein Is Enough in A Low Protein Diet?
Generally, your body needs around 40-60 gm of protein every day or 0.8g of protein per kg body weight, based on your activity level. Therefore, if you weigh 60 kg and perform very less to no physical workout, you will need 48 gm of protein every day. In case you are overshooting that stop, you must lower your protein consumption to 0.5 to 0.6 g/kg body weight based on the kidney’s condition and requirement. Also, take your doctor’s advice.

Recent Study about low protein diet benefits
According to a recent study, the low protein diet benefits finds a strong link with a low risk of cardiometabolic ailments.
Proteins are formed of 20 types of amino acids. Sulfur amino acids are a sub-category of amino acids, which are a necessary dietary component for overall health. The stable nutritional need levels for complete sulfur amino acids are 15mg per kg every day and advised for a daily allowance of 19 mg per kg per day. Earlier research in animals has suggested that lowering the sulfur amino acid consumption could raise life expectancy and decrease cardiometabolic ailments.
In a recent study, researchers analyzed the data of a survey from 11,576 healthy participants from the US. These surveys were taken in a national study from 1988-1994. The data of selected people were inspected into five groups based on complete adjusted sulfur amino acid consumption. The research took dietary information from the survey and determined a composite cardiometabolic disease risk score. The composite risk score was based on the biomarkers, such as kidney functions, blood pressure, total cholesterol levels, blood sugar levels, triglycerides, hemoglobin, and C-reactive protein.
The risk score was determined from 0-12 with 12 indicating the highest risk. The researchers also discovered risk factors that may affect sulfur amino acid consumption, such as sex, age, body mass index, alcohol intake, smoking, and diet.
The researchers discovered that sulfur amino acid consumption was more from animal protein compared with grain, vegetable, fruit, and legumes. The study reported significantly more intake of sulfur amino acids that were advised, which were linked with an increase in cardiometabolic disease risk.
Signs of Protein Deficiency
How Much Protein Do You Need?
You ought to get at least 10% of your everyday calories from protein. (For an aim of grams, multiply your weight in weights by 0.36.) And you need it from an assortment of sources for the day. A tub of less-fat Greek yogurt for breakfast has about 20 grams; a serving of skinless chicken bosom at lunch, around 25 grams; and a cup of dark beans in your supper, around 15 grams. Your body separates and reuses the protein in several ways.
Swelling
Swelling is another common sign of not having sufficient protein. You will notice swelling in the legs, feet, abdomen, and hands. The proteins, which circulate in the blood are called albumin, especially to help the fluid balance in the tissues. But different things can cause edema. Therefore, make sure to take your physician’s advice.
Mood Changes
Your brain utilizes synthetic compounds named neurotransmitters to hand-off data between cells. More numbers of these neurotransmitters are formed by amino acids, which are the building squares of protein. So a lack of protein in your eating regimen could mean your body can’t make plenty of those neurotransmitters, and that would improve how your mind functions. With low levels of serotonin and dopamine, for example, you may feel sad or excessively aggressive.
Hair, Skin, Nail, and Problems
These are formed of proteins like collagen, elastin, and keratin. When your body can not enough, you could have thinning or brittle hair, flaky or dry skin, deep ridges on fingernails. Your diet is not the one cause, but it is also something to consider.
Weakness and Fatigue
Research tells that a week of not getting sufficient protein can influence the muscles responsible for your movement and posture, especially if you are 55 or older. Gradually, lack of protein can cause you muscle mass loss, which cuts the strength and cause imbalance and slow down the metabolism. It can also cause anemia when your cells do not get enough oxygen and make you tired.
Staying Sick
Amino acids in the blood help the immune system create antibodies, which activate white blood cells to fight off viruses, toxins, and bacteria. You need protein to digest and absorb other nutrients to keep you healthy. There is also evidence that protein can alter the good bacteria in the gut.
Hunger
It is one of the signs of protein deficiency. It is one of three sources of calories, along with fats and carbs. If you wish to eat more even after regular meals, you may be lacking protein. Studies have shown that consuming foods with protein helps to make you full in the entire day.
Slow-Healing of Injuries
People who are suffering from low protein often get their cuts and scrapes take more time to get better. The same seems to be real of sprains and other workout-related mishaps. It could be another effect of the body not forming sufficient collagen. It is available in connective tissues and skin to make blood clot, that’s why it needs protein.
What About Athletes?
If you work out continually and eat a well-balanced diet, you are probably good. But serious athletes performing strenuous training schedules require more protein about twice as much as the normal person or 0.5-1 grams of protein per pound of body weight every day. Avoid overdoing it and too much protein can also problem you.
Risks Linked with A Low-Protein Diet
- Following a diet with low-protein continually affect the important functions of cells, such as immune response and wound healing.
- A low protein diet can cause muscle loss.
- This diet has low calcium, iron, thiamine, niacin, riboflavin, and another nutritional supplement, which need physician recommendation.
- Raise the infection risk.
- It may harm the heart is fat, and sugar sources are not balanced.
- It may cause tooth decay.
- The low-protein diet reduces serum albumin levels and causes edema.
