2. Protein is critical for maintaining a healthy metabolism. This is because it requires more energy (calories) to digest and absorb protein than carbohydrates and fats. The thermic effect of food (TEF) refers to the energy the body uses to digest, absorb, and process the food we eat. This metabolic process requires energy, and the amount of energy used depends on the type of food consumed. Essentially TEF implies that consuming protein can increase the number of calories your body burns at rest.
3. Protein is more satiating than carbohydrates and fats because of its impact on several hormones and neurotransmitters that regulate hunger and provides a longer-lasting feeling of fullness, which helps control appetite and reduce overall calorie intake. In addition, high-protein diets have been shown to help regulate insulin levels, leading to better blood sugar control and reducing food cravings.
4. Protein is essential for forming bone tissue and plays a vital role in maintaining bone health. Bones are composed of collagen, a type of protein, and other minerals that work together to provide the strength and stability needed for our bones to function properly. When the body has insufficient protein in the diet, bone tissue can begin to break down, resulting in a loss of bone density, increasing the risk of osteoporosis.
5. Protein plays a crucial role in supporting the immune system. The immune system relies on various cells and proteins to protect the body from pathogens and other harmful substances and repair and rebuild damaged tissue. Therefore, when the body is deficient in protein, it may not be able to support a strong immune response. However, it’s important to note that a diet high in protein alone is insufficient for a healthy immune system; the body also requires a balanced diet with enough vitamins, minerals, and other nutrients. In addition, a healthy lifestyle that includes regular exercise, adequate sleep, and stress management also supports the immune system.
