Protein is an essential macronutrient that provides structure and support to cells and protects the body from viruses and bacteria. It is a building block for bones, skin, muscles, and more. A protein-rich diet is necessary for growth and development, especially in children and adolescents. While protein deficiency is rare in developed countries, it can have adverse effects on the body, including swelling, stunted growth, weak bones, and a compromised immune system. A lack of protein can also lead to muscle loss, changes in hair and skin, and increased susceptibility to infections. To maintain adequate protein intake, it is recommended to consume protein-rich foods like beans, legumes, meat, seafood, eggs, and nuts.

- If you exercise, you need more protein to build and maintain muscle
Protein deficiency is rare in the West but common in developing countries
Protein deficiency, or protein–energy malnutrition, is a form of malnutrition characterised by a lack of protein in the diet. While it is rare in Western countries, it is still a common issue in many developing nations.
In the decades following World War II, nutritional scientists almost universally believed that protein deficiency was the most serious and widespread dietary issue globally. As a result, improving protein nutrition became a high priority for organisations such as the Food and Agriculture Organisation of the United Nations. This focus on protein deficiency has persisted, even though official recommended daily allowances (RDA) suggest that deficiency is very unlikely.
Protein–energy malnutrition is particularly prevalent in southern Asia and sub-Saharan Africa. In these regions, diets are often deficient in macronutrients (including protein, carbohydrates, and fats) and micronutrients (such as electrolytes, minerals, and vitamins). This leads to specific micronutrient deficiencies, including iron, iodine, vitamin A, and zinc deficiencies, which are major public health problems in developing countries. The high prevalence of bacterial and parasitic diseases in these regions also contributes to malnutrition, as malnutrition increases susceptibility to and the severity of infections.
In recent years, there has been a shift in focus from protein malnutrition to micronutrient malnutrition in developing countries. This shift is reflected in the founding of organisations such as the International Vitamin A Consultative Group (IVACG) and the International Council for the Control of Iodine Deficiency Disorders. While protein–energy malnutrition has decreased in some countries, such as China, it has increased in other developing regions.

Protein fuels you and makes you feel full, so a lack of it increases your appetite
Protein is an essential macronutrient that provides structure and support to cells and protects the body from viruses and bacteria. It is one of three sources of calories, along with carbohydrates and fats. Eating protein helps you feel fuller throughout the day, and a lack of it increases your appetite.
Protein suppresses the hunger hormone, ghrelin, and increases the appetite-reducing hormones cholecystokinin, GLP-1, and peptide YY. A 2010 study in overweight men found that increasing protein to 25% of calories reduced cravings by 60% and halved the desire to snack at night. Similarly, a 2014 study in overweight adolescent girls found that a high-protein breakfast reduced cravings and late-night snacking.
Protein-rich foods are often more expensive than foods high in carbohydrates and fats, and snack foods tend to have minimal protein content. This may explain why some people tend to eat less protein. However, a low-protein diet can lead to overeating overall, as the body tries to avoid a protein shortage, resulting in increased consumption of fats and carbohydrates.
A lack of protein can lead to muscle loss, which reduces strength, impairs balance, and slows metabolism. It can also cause skin and hair changes, including dryness, flakiness, and hair breakage. Severe protein deficiency, or kwashiorkor, is uncommon in the United States but prevalent in developing countries, especially among children. It is characterized by swelling in the arms and legs due to low protein in the blood.
The recommended daily protein intake for healthy individuals is 46 grams for adult females and 56 grams for adult males. However, individual needs may vary, and consulting a healthcare professional is advisable to determine one's specific requirements.

A protein-deficient diet can cause swelling, stunted growth and a weak immune system
Protein is a vital nutrient, and insufficient intake can lead to various health issues. A protein-deficient diet can cause swelling, stunted growth, and a weak immune system, among other problems.
Swelling, known as edema, is a common sign of inadequate protein intake. Edema is characterised by swollen and puffy skin, typically noticed in the abdomen, legs, feet, and hands. This occurs due to low levels of albumin, a protein that helps maintain oncotic pressure, preventing fluid buildup in tissues.
Protein deficiency can also lead to muscle wasting and loss of muscle mass, particularly in older adults. The body, in an attempt to preserve critical functions, takes protein from skeletal muscles, resulting in reduced strength, balance issues, and a slower metabolism. This muscle wasting can also contribute to stunted growth, especially in children.
Additionally, a protein-deficient diet can weaken the immune system. Protein is essential for building antibodies that fight infections. Research has shown that individuals with a high-protein diet had fewer upper respiratory tract infections compared to those with a low-protein diet.
Other symptoms of protein deficiency include hair loss, dry skin, increased infections, fatigue, and increased hunger. It is important to note that severe protein deficiency, known as kwashiorkor, is uncommon in Western societies and is more prevalent in developing countries, often affecting children.

It can also lead to muscle loss, weak bones and a higher risk of infection
A lack of protein in the diet can have various adverse effects on the body. One of the most significant consequences is muscle loss. When the body does not get enough protein, it starts breaking down skeletal muscle tissue for energy, leading to a decrease in muscle mass and strength. This muscle atrophy can affect posture and movement, making it difficult to maintain balance and perform physical tasks.
Additionally, insufficient protein intake can contribute to weak bones. Protein, especially collagen, is a crucial component of bone structure. A diet lacking in protein can result in decreased bone mass and strength, making individuals, especially older adults, more susceptible to fractures and osteoporosis.
Protein deficiency can also weaken the immune system, making it harder for the body to fight off infections. Amino acids in protein help the immune system produce antibodies that activate white blood cells to combat viruses, bacteria, and toxins. A lack of protein can reduce the body's ability to produce these antibodies, increasing the risk of infection and prolonging recovery from injuries and illnesses.
The impact of inadequate protein consumption can vary depending on age, overall diet, and health conditions. While severe protein deficiency is uncommon in developed countries, it can occur in individuals with poor diets, elderly people, and those with certain illnesses. It is essential to consult a healthcare professional if you are concerned about your protein intake to ensure you are getting sufficient protein to maintain overall health and well-being.

If you exercise, you need more protein to build and maintain muscle
Protein is an essential macronutrient that supports growth and repair in the body. It is a major component of skin and hair, and it helps make and repair cells, which are critical for growth and development. When you exercise, your muscles and their proteins break down, and replacing them with new proteins helps your body recover from exercise, repairing muscles and helping them get stronger.
If you exercise regularly, you need more protein to build and maintain muscle. The recommended dietary allowance to prevent deficiency for an average sedentary adult is 0.8 grams of protein per kilogram of body weight. However, if you are physically active, your protein needs increase. The recommended amount of protein for active individuals is between 1.1 and 1.7 grams of protein per kilogram of body weight per day. This amount can vary depending on the type of exercise, with endurance athletes and weightlifters requiring more protein than those who engage in moderate exercise.
It is important to note that while protein is crucial for muscle growth and maintenance, consuming too much protein may pose health risks. Excess protein intake can lead to weight gain as the body stores excess calories as fat. Additionally, it can increase the risk of elevated blood lipids and heart disease, especially if the high-protein diet is rich in total and saturated fats. For individuals predisposed to kidney disease, a high-protein diet can be harmful as it taxes the kidneys. Therefore, it is essential to consult a healthcare professional or a dietitian to determine your individual protein needs based on your age, gender, activity level, and other factors.
To ensure adequate protein intake, it is recommended to consume protein with each meal and snack. Complete proteins, which contain all nine essential amino acids, are particularly beneficial and are mostly found in animal sources such as beef, poultry, eggs, and dairy. However, some plant-based proteins like rice, beans, and quinoa are also complete proteins. Spreading out protein consumption evenly throughout the day is generally recommended, with 15 to 30 grams of protein per meal being a common guideline.
