To function daily, your body gleans energy from three food-derived macronutrients: carbohydrates, fats and proteins. How you divvy up those macronutrients in your diet is a matter of personal preference.
But what if you could train your brain to prefer one macronutrient over the other?
After all, not all macronutrients are created equal. While carbohydrates and fats are stored as inert forms in the body for later energy use, proteins are broken down to amino acids, which provide the biochemical basis for muscle, hormones, enzymes and neurotransmitters, among other important molecules. When demand for amino acids exceeds the dietary supply, our bodies respond by breaking down muscle and other functional proteins.
