Macromolecules, or as they are better known, macros, are type of naturally occurring and heavily needed resource in the body. The four types of macros are proteins, lipids, nucleic acids, and carbohydrates. In order to support the growth and maintenance of the human body, and especially muscle growth, one must eat the proper amounts of each of these molecules. If adequate intake isn't fulfilled, the body can't grow and going to the gym, or doing any physical activity, is actually harmful. This is why I find it imperative to do a deep dive into macro molecule intake for my goals.
