Metabolic Typing is all about matching your diet to your own unique needs. These needs are determined by the way that some of your regulatory control systems operate.
These regulatory control systems - such as the Autonomic Nervous System, AKA the master regulator of metabolism, and your Oxidative rate, (the rate at which your body metabolises, or converts foods and nutrients into energy) determine how efficiently your body works, and how they manage your body processes.
This knowledge can tell you what kind of proteins, fats and carbohydrates you need and also in what ratios you need them. William Wolcott discovered in 1983 that each of us is dominant in one of these systems and he called this the Dominance factor. This discovery essentially explains that any food and any nutrient can have opposite biochemical effects in different individuals, or different Metabolic Types.
