17 Feb 2014 Fats, carbohydrates and proteins are a group of nutrients known as the macronutrients. Macronutrients are the body's source of energy (calories) fueling daily activities, exercise and recovery from injuries. Protein is a special macronutrient because unlike fats and carbs, it provides the building blocks for all tissue within the body. The body uses protein to build new tissues and repair damages ones. The gym-community sees protein as a muscle building miracle food; more protein=more muscle. Unfortunately this isn't always the case. Many people eat way too much protein leading to excessive increases in body fat rather than faster muscle growth.
