This has a ton of info on it if you look under the library.
The basics are here:
From the FAQ:
QUESTION: My doctor says a balanced diet is all I need to stay healthy, and I do eat as healthfully as I can. Yet, I still feel like I'm running on empty and like there is something my body must be lacking, or I would feel better.
HEALTHEXCEL: The failure to acquire all the nutrients for which one has a genetic requirement expresses itself in different ways in different people. For some, it's intense cravings; for others, it's feeling hungry five minutes after eating a big meal; for you, it's feeling like you are running on empty; for others, it's something else. Regardless of the specific form it takes, it's just your body's way of communicating, it's your body's language, saying that it did not get the right balance of nutrients to meet its needs.
Your doctor is very right; one should eat a well-balanced diet in order to be healthy. The question which naturally follows, of course, is what constitutes a well-balanced diet? Actually, what constitutes a well-balanced diet for one person, very likely is not right for someone else. The high protein, fat diet of the Eskimo certainly is not right for the vegetarian East Indian. The basis for the determination of what diet is correct for any given individual is a matter of genetic inheritance. Just as your genes dictate your height, bone structure, color of eyes, strength of your digestive system, the efficiency of your immune system, the rate of your cellular metabolism and all the innumerable characteristics which make up the unique biochemical and biological wonder that is YOU, so too, do your genes deter-mine the requirements your body has for fuel. In order to find out what a well-balanced diet is for you, you would need to determine your metabolic type.
QUESTION: What is the difference between Metabolic Typing and Blood Typing? Is a Metabolic Type the same thing as a Blood Type?
HEALTHEXCEL: With the advent of the recent book on blood types, Eat Right 4 Your Type by Peter D'Adamo, N.D., we are often asked if blood typing is the same as metabolic typing. In short, no. Actually, one's blood type is just 1 of 9 different components used in the process of metabolic typing to determine individual nutritional requirements. Here are the components that we have discovered are necessary to consider in evaluating your metabolic type:
1. Autonomic Nervous System (ANS) – the “master regulator” of metabolism
2. Oxidative System – rate at which nutrients are converted to energy within the cells
3. Catabolic/Anabolic – aerobic / anaerobic metabolism, tissue pH, selective membrane permeability
4. Acid / Alkaline Balance – 6 different kinds of pH imbalances
5. Electrolyte Stress / Insufficiency – concerned with blood pressure, circulation, electric potential
6. Endocrine Type – determines body type, shape, weight gain, etc.
7. Constitutional Type – from AyurVeda and Chinese medicine, concerned constitutional qualities of foods relative to constitutional qualities of indivisual
8. Blood Type – food lectins specific to ABO blood types
9. Prostaglandin Balance – Series 1, 2, 3 prostaglandin balances
10. Neurotransmitter Balance – balance of excitatory vs. inhibitory neurotransmitters control brain function
The blood type has more to do with what few foods should be left out of your diet due to their lectin content specific to your blood type. But blood type has little to do with what foods and nutrients should be eaten. For that, we need to consider the body's primary mechanisms that specifically regulate how energy is created, maintained and controlled, such as the ANS, Oxidative System and Catabolic/Anabolic processes. And whereas the blood type is static, non-changing, the different balances, strengths and weaknesses in the other fundamental control mechanisms can and do change.
What is most important to know is that every food and every nutrient has very specific stimulatory or inhibitory effects on these fundamental homeostatic control systems that regulate every process in your body at every level of activity. This is why getting the right nutrition is so critical. Moreover, through metabolic typing we have learned that any food or nutrient can have different effects on different metabolic types. As it turns out, the old adage that “one man's food is another's poison” is literally true. Fact is, you can eat the best organic foods, take the best supplements money can buy, get plenty of rest, exercise regularly and still not feel well. Why? Because you did not eat those foods for which your body has a specific, genetically-based requirement. Only through metabolic typing can you be assured that your food will be the medicine God intended it to be.
QUESTION: My sister, my best friend and I all embarked on Dr. Atkins' weight loss program* with gusto, expecting fantastic results. Two of us got them and one of us didn't . . . guess who? I ended up gaining the weight that each of them lost and feeling terrible to boot, and even though I've been off the diet for 3 weeks now, I can't even look at food without putting on more weight! Is there anything in your program that might make a loser out of me? Sounds strange, but I wouldn't mind having that title!
[Note: The Atkins program is a well-known high-protein, high-fat diet. Similar questions have been received in regard to the Pritikin diet, a low-fat, low-protein diet. The same answer would apply to all such questions. -Ed ].
HEALTHEXCEL: Yours is not, by any means, an uncommon problem and illustrates wonderfully the concept of what is referred to as biochemical individuality, which is just a fancy way of saying that you are unique and that therefore, your body has unique requirements for nutrition.
Weight is an important consideration in one's overall picture of health. Each person has a genetically programmed ideal weight. This is simply the weight at which you look and feel your best. While being overweight may be a symptom of imbalance, or even in some cases, lack of health, losing weight is not necessarily the same as obtaining good health. However, empirical findings have found the normalization of weight to be a natural by-product of balancing body chemistry and building health, which results from the natural maximization of your body's energy potential.
There are two main considerations in the healthful and successful process of weight loss through balancing body chemistry. The first and most important, is that you must acquire the right fuel mixture in the nutrients that you ingest. If the food that you eat does not provide the right balance of nutrients for your genetic needs, then it won't be adequately oxidized (burned for energy) in the cells and will end up being stored as fat; and your body's energy levels will be disrupted, causing you to not feel well, besides put on more weight.
The second consideration is the one everyone is familiar with caloric intake. If one continues to take in more calories than are burned, one will gain weight. However, the key is eating the foods that are right for your type. In so doing, you will be balancing your body chemistry, maximizing your energy production, burning your calories more efficiently, and satisfying your appetite because your are supplying your body with all that it needs. The only way to lose weight, keep it off and feel wonderful at the same time, is to balance your body chemistry and maximize your energy potential.
