Whether strength athletes and bodybuilders achieve their goals largely depends on optimal nutrition. In this book, Philipp Rauscher explains in detail what to consider when composing meals and what really matters when aiming for perfect muscle definition and body composition. It is particularly important to accurately determine energy needs, adjust proteins, fats, and carbohydrates, and pay attention to the right meal frequency and the timing of different nutrients. Myths such as the 30-gram rule for proteins are debunked, as well as the claim that high dietary fat automatically leads to increased body fat. Instead, the importance of dietary fats for strength athletes and bodybuilders is explained, with a closer look at the differences between individual fatty acids and their significance, as well as the metabolism of protein.
