You now understand the physiology of fat cells, the truth about body composition, the engine of your metabolism, and the specific roles of each macronutrient.

Fitness is, at its core, biology driven by mathematics. If you know your numbers, you remove all the emotional guesswork from the process. When the scale spikes by 3 pounds on a Tuesday, you won't panic, because you know the math proves you couldn't have gained 3 pounds of fat.
