Protein is an essential part of a healthy diet. It is a macronutrient that makes up a large part of our cells and provides the amino acids that keep our bodies functioning. However, some people choose to cut down on or eliminate protein from their diets, often to control weight and fuel workouts. While this may lead to short-term weight loss, it can also have negative side effects on the body, including a weakened immune system, skin and hair changes, and bone and muscle loss.
What Happens if You Cut Protein Out of Your Diet?
| Characteristics | Values |
|---|---|
| Feeling unsatisfied after meals | Protein increases the release of an appetite-regulating protein, keeping you fuller for longer. |
| Increased hunger | As above. |
| Weight loss | A high-protein diet can contribute to weight loss and prevent weight regain. |
| Increased risk of stress fractures | Protein is essential for bone restoration. |
| Hair and skin changes | Protein is a major component of skin and hair. Deficiency can cause skin to appear paler, drier, or flakier, and hair to become more brittle and break more easily. |
| Weakened immune system | Protein helps make antibodies that protect from infection and illness. |
| Impaired muscle growth | Protein is essential for muscle growth and repair. |
| Kidney problems | Too much protein can negatively affect conditions like kidney disease. |

What You'll Learn
You may experience hair and skin changes
Protein is a major component of skin and hair. A protein deficiency can cause skin to appear paler, drier, or flakier. You may also experience hair loss or greying. Your hair may become more brittle and break more easily.
Hair and skin changes do not usually occur with marasmus, a form of severe malnutrition that happens if you do not eat enough calories or protein, resulting in extreme weight loss and muscle wasting. However, low protein intake can trigger telogen effluvium, a condition that leads to excessive hair shedding and hair loss.
Keratin, collagen, and elastin are proteins responsible for healthy hair and nails. Keratin provides strength and structure to the skin, hair, and nails. Collagen is the most abundant protein in the body and is one of the major building blocks of bones, skin, muscles, and ligaments.
A severe protein deficiency can impair your immune system. Protein helps make antibodies that protect you from infection and other illnesses. Lower protein intake is often associated with a lower intake of other nutrients.

Your bones may be more susceptible to injuries
Protein is essential for optimal bone mass gain and the preservation of bone and muscle mass as we age. A low protein diet can lead to reduced bone development and an increased risk of fractures.
The International Osteoporosis Foundation highlights the importance of adequate dietary protein for bone health. During childhood and adolescence, protein plays a critical role in bone mass acquisition. Undernutrition during these formative years can impair bone development. Low protein intake lowers the production and action of Insulin-like Growth Factor (IGF-1), which enhances bone formation and stimulates the intestinal absorption of bone minerals such as calcium and phosphate. IGF-1 also promotes the renal tubular reabsorption of phosphate, contributing to bone health.
Additionally, a positive correlation between protein intake and bone mass gain has been observed in children. This relationship between dietary protein and bone health continues into older age, where it becomes critical.
Several studies have found a link between low protein intake and reduced bone density, as well as increased rates of bone loss. While the exact mechanism is not fully understood, it is hypothesized that a high endogenous acid load from a protein-rich diet may increase bone resorption and skeletal fracture. However, this hypothesis remains unproven, and more research is needed to understand the direct impact of low protein intake on bone health.
Furthermore, other nutrients obtained from protein-rich foods also contribute to bone health. For example, zinc, found in lean red meat, poultry, and whole-grain cereals, is required for bone tissue renewal and mineralization. Similarly, vitamin K, abundant in green vegetables and legumes, is necessary for producing osteocalcin, a protein vital for bone health.

You may feel hungry throughout the day
Protein is an essential component of a healthy diet. It is a macronutrient that makes up a large part of our cells and provides the essential amino acids that our bodies need to function. However, not consuming enough protein can have adverse effects on the body, and you may feel hungry throughout the day.
Protein helps regulate appetite and keeps you feeling full for longer. When you don't eat enough protein, you may feel unsatisfied after meals and tend to get hungrier sooner. This is because protein increases the release of an appetite-regulating hormone, which keeps you satiated for longer durations.
The body requires an adequate supply of protein to support the continuous restoration process of bones. When there isn't enough protein to fuel vital organs, the body borrows protein from other areas, including skeletal muscle tissue. This leads to weaker bones that are more susceptible to injuries and fractures.
Additionally, protein is crucial for healthy hair and skin. A deficiency in protein can cause skin to appear paler, drier, or flakier. Hair may become more brittle, break more easily, and experience hair loss or greying.
Protein is also essential for a strong immune system. It helps produce antibodies that protect the body from infections and illnesses. A lack of protein results in a lower number of antibodies, increasing the risk of infections. Therefore, it is important to ensure that you are consuming an adequate amount of protein daily to maintain optimal health and prevent feelings of hunger throughout the day.

You may be at a higher risk of infection
Protein is one of the body's main building blocks and is found everywhere in the body, including in muscles, skin, hair, bones, and blood. It is a key player in the structure and function of muscles, skin, enzymes, and hormones.
Protein deficiency is uncommon in the Western world but can occur due to malnutrition, pregnancy, eating disorders, liver disorders, kidney problems, and inflammatory bowel diseases. It can also be caused by limiting food intake or following highly restrictive diets. A person can become protein deficient when their intake is unable to meet their body's requirements.
A protein deficit may compromise your immune system, making it harder for your body to resist infections. A 2013 study found that male athletes who consumed a high-protein diet experienced fewer upper respiratory tract infections than those on a low-protein diet. Protein is important for building antibodies, which are produced by white blood cells to help fight infections.
Severe protein deficiency can lead to a condition called hypoproteinemia, which is characterised by having too little protein in the blood. This can be caused by the reduced absorption of nutrients, including protein, in the small intestine due to inflammatory bowel disease. It can also occur when the liver is not functioning properly, preventing the body from getting enough protein to carry out its vital functions. In addition, kidney damage or dysfunction can lead to proteinuria, where protein leaks into the urine, resulting in low protein levels in the body.
If you think you may be protein deficient, it is important to speak with a healthcare professional or registered dietitian. They can help you manage your protein levels and make any necessary dietary changes.

You may experience stunted growth
While cutting out protein from your diet may not be a good idea, completely removing it is quite rare. Protein deficiency is uncommon in the Western world, but some people may get very low amounts from their diet.
Protein is one of the body's main building blocks, and a lack of it can affect almost all aspects of body function and lead to various health problems. Protein plays a key role in the structure and function of muscles, skin, enzymes, and hormones. It is also important to help build antibodies, which help fight infections. A protein-rich diet is also linked to better appetite maintenance and total calorie intake.
Protein deficiency is more common in children, especially in developing countries with high levels of poverty and food insecurity. Stunted growth is one of the most common signs of childhood malnutrition. A lack of essential amino acids and choline in the diet has been linked to stunted growth. Essential amino acids are the building blocks of proteins and are necessary for human health. However, they must come from dietary sources as the body cannot produce them. Animal sources such as eggs and dairy products can provide these essential nutrients.
Kwashiorkor, a type of malnutrition characterized by severe protein deficiency, can cause stunted growth in children. It is commonly seen in children in developing countries and can lead to fluid retention, swollen abdomen, and developmental delays.
