Coach Josh breaks down the three macronutrients, protein, carbohydrates, and fat, and why almost everyone in a group poll was already focusing on protein. He explains that fat supplies more than twice the energy per gram of protein or carbohydrate, that carbohydrate mainly fuels performance, and that protein is the building block you cannot skimp on. He generally recommends about 1.6 grams of protein per kilogram of body weight, in a range of about 1.2 to 2 grams, and warns that nuts are a poor way to hit a protein target.
