Proteins are very important for our body. They represent the main building material for cell construction and are involved in all chemical processes in the body. They are crucial for creating hemoglobin, responsible for oxygen transport in the blood, as well as essential for building muscle tissue, hair growth, nail strength, and skin health.

Proteins are found in nearly all foods except refined sugar and fats. The highest amounts of animal proteins are in meat, fish, eggs, milk, yogurt, and cheese. Plant-based proteins can be found in legumes (beans, peas, lentils), grains, leafy green vegetables, and buckwheat. An adult needs 1.0 to 1.5 grams of protein per kilogram of body weight.

1. Craving for sweets

One of the first signs that your body lacks proteins is a craving for sweets. Have you ever wondered why you never crave meat and eggs? One of the roles of proteins is to maintain blood glucose levels. If you lack proteins, your glucose levels drop, leading to a craving for sweets. Sugar is a quick energy boost that can lead to weight gain. Many vegetarians gain weight due to inadequate protein intake.

2. Feeling of fatigue

Again, sugar plays a major role. Lack of sugar causes a drop in concentration, lack of energy, and fatigue. If your brain lacks enough proteins, you may feel tired and irritable. Many mistakenly seek a solution in carbohydrates, sweets, pastries... This is only a temporary solution, as energy from carbohydrates depletes quickly.

3. Hair loss

Proteins are important for cell construction, including hair regeneration. In addition, hair becomes thinner, more brittle... Besides hair, eyelashes, eyebrows, and other body hair may start falling out due to protein deficiency.

4. Feeling unwell

In addition to fatigue, protein deficiency is also accompanied by feeling unwell, even muscle pains. Importantly, proteins start to take effect only after a few hours (up to 4 hours).

5. Low immune system

If you often feel like you're coming down with an illness, but then don't get sick the next day, and this cycle repeats multiple times a week, the reason is likely protein deficiency.
