What is the primary role of protein in the body?

The primary role of protein in the body is to facilitate muscle repair and growth. When you engage in physical activity, especially strength training or intense workouts, muscle fibers experience micro-tears. These tears need to be repaired to enhance muscle strength and size, a process that heavily relies on protein.

Proteins are made up of amino acids, which are the building blocks necessary for the synthesis of new muscle tissue. Consuming adequate protein supports recovery post-exercise, helps in rebuilding the damaged muscle fibers, and can promote hypertrophy when paired with resistance training. This is particularly significant for athletes and individuals aiming to increase their strength or muscle mass.

While proteins can provide some energy, especially during prolonged exercise or when carbohydrate stores are depleted, their primary function revolves around growth and repair, which distinguishes them from carbohydrates and fats that are typically more direct energy sources.
