Metabolic Limbic System

Over the last 35 years I have practiced the concepts of what is now called “Metabolic Typing”. It has been called many things by many people over the years trying to put a new spin on it.

A big part of this area of Metabolic Typing is attached to the Central Nervous System. In particular the Autonomic Nervous System and the Limbic System.

Autonomic Nervous System

The ANS, referred to as the master regulator of metabolism, has two divisions: the Sympathetic and the Parasympathetic. Each works in opposition to the other, yet they work together to maintain homeostasis ( metabolic balance and efficiency ). For example, Sympathetic nervous stimulation speeds the heart rate, while Parasympathetic stimulation slows the heart rate.

Together, the Sympathetic and the Parasympathetic divisions work to maintain the proper heart rate, as well as the functioning of all the various organs and glands. Certain organs are “switched on” by the Sympathetic and “switched off” by the Parasympathetic, while other organs are “switched on” by the Parasympathetic and “switched off” by the Sympathetic.

Some people have inherited stronger organs and glands that are stimulated by the Sympathetic division. These people are known as the Sympathetic Metabolic Types. Other people have inherited greater strength overall in the Parasympathetic organs and glands and are known as Parasympathetic Metabolic Types.

Oxidative System

While it might be said that the ANS is concerned with maintenance and regulation of energy, the Oxidative System concerns the rate at which nutrients are converted to energy within all of your body’s 100 trillion cells.

There are three process involved:

Some people are Fast Oxidizers — they are poor at metabolizing fats and producing Acetyl Co-A from Beta Oxidation and so they are overly reliant on the combustion of carbohydrates in Glycolysis for energy production.

Fast Oxidizers tend to burn carbohydrates too quickly and thus they produce excess Oxaloacetate. A high carbohydrate diet only worsens the problem, but increased amounts of fats and proteins ( dietary sources of Acetyl Co-A ) and specific nutrients to help activate and support Beta Oxidation, help balance their chemistries and normalize their energy production.

Slow Oxidizers have the same problem as Fast Oxidizers — deficient energy production — but for the exact opposite reasons. Slow Oxidizers are overly reliant on fat metabolism in Beta Oxidation, so they produce excess Acetyl Co-A, but they are also poor at carbohydrate combustion in Glycolysis, and tend to be deficient in the production of Oxaloacetate.

Unlike the Fast Oxidizers, Slow Oxidizers do well on higher carbohydrate intakes ( dietary sources for oxaloacetate ) with less protein and fat in their diets ( sources of Acetyl Co-A ) and they require different nutrients to activate and support Glycolysis.

Certain foods stimulate, strengthen and support the Parasympathetic System ( alkalinize ), while other foods stimulate, strengthen and support the Sympathetic System( acidify ). In the Oxidative System, the effects of these same foods are actually reversed! This is why nutrition can be so confusing, complex and unpredictable.

Foods. You eat it several times a day, every day of your life. It contains hundreds upon hundreds of compounds that your body uses as its “fuel for life.” Your food can be your medicine or your poison. It has the power to heal. But it also has the power to make you ill if you eat foods that are wrong for you. With the exception of accidents and suicide, the 10 leading causes of death in the US can all be caused by eating the wrong diet, and all of them have been cured by eating the right diet!

It’s not only what you eat, it’s also in what proportions you consume your macro-nutrients ( proteins, fats, and carbohydrates ) that will allow you to maximize your energy, develop peak performance, normalize your appetite and be as trim as you can be. After eating, you should feel an elevation of your energy, a normalization of your moods, and a sense of feeling satisfied.

If, within 1-2 hours after eating, you feel more tired, or your mood worsens, or you still feel hungry, crave sweets or feel like you need a “pick-me-up,” then you need to change the ratio of proteins, fats and carbohydrates at that meal until your symptoms improve.

Balanced Metabolic Type

In people who have a balanced autonomic nervous system, neither branch is stronger. They neither burn their food too fast or two slow, and they do equally well (or poorly, if they are sick) on all variations of foods. When they become sick, they can be prone to the conditions of either Sympathetics or Parasympathetics, but generally not to the extreme of either type.

It is not better or worse to have a sympathetic or parasympathetic dominant or balanced metabolism, although balanced metabolisms have more freedom in food choices. Regardless of your dominant metabolic type, you can be wellnessy or sick.

Parasympathetic Primary Type

Parasympathetic primary people have a stronger immune system, pineal gland, lungs, adrenal cortex (which secretes cortisone), spleen and digestive system — stomach, intestines, liver, gall bladder and pancreas. They have good digestion and are fast oxidizers (meaning they digest food and burn sugar rapidly). They tend to be relaxed and easy-going, even lazy or lethargic, and don’t like to be rushed. They are strong people with enduring energy and a high stress tolerance, unless the stress becomes too much for them and then they fall apart. They have large appetites, are usually hungry, enjoy fatty and salty foods, and don’t like to exercise.

Parasympathetics are generally slow to anger, are friendly and talkative and make great salespeople. Their body cells are alkaline, so in spite of the prevalent belief that meat is unwellnessy for everyone, they need to eat meat. If they are very parasympathetic, they especially need liver and other glands. (Organic meat preferred.  Kosher is second choice.)

They tend to have large frames, ruddy complexions and small eyes. The conditions parasympathetic dominant people are prone to include hypoglycemia (low blood sugar), diarrhea, overweight, low blood pressure, depression, heavy sweating and frequent urination, viral infections, allergies, asthma, cold sores, leukemia, osteoarthritis, and sexual problems (impotence in males and menstrual/menopause problems in females). If they have a heart attack, it is usually massive and kills them.

Sympathetic Primary Type

Sympathetic primary people have a stronger muscular system, heart, thyroid gland, parathyroid gland (responsible for calcium metabolism), kidneys, gonads, (ovaries or testes), uterus or prostate and adrenal medulla (the part of the adrenal gland that secretes adrenaline). The adrenal medulla is often over-active in Sympathetics and they are typical “fight or flight” Type A people – “workaholic” executives, self-motivated leaders and high-pressure business people.

They have lots of nervous energy, are ambitious, enjoy exercise, love mental stimulation, have excellent powers of concentration, seem to be in constant motion and function well under stress. Sympathetics are anxious, impatient, quick to anger and have emotional swings, but they are rarely depressed. They enjoy vegetables, fruits and sweets and have good calcium metabolism. They are slow oxidizers (meaning they digest food and burn sugar slowly) and their cells are more “acidic.”  They generally thrive on vegetarian or modified vegetarian diets, with chicken, fish and just a little meat.

Sympathetic primary people tend to be slender and pale, with big eyes. The conditions they are prone to include constipation, diabetes, digestive problems, anemia, cancer, high blood pressure, bacterial infections, non-fatal heart attacks, poor circulation, migraine headaches, insomnia, rheumatoid arthritis and hardening of the arteries. Because they are so busy, they may “forget” to eat.

They tend not to “feel” sick (no time to be sick), so they don’t slow down even when they need to, with sympathetic primary people are “fast paced” left-brain Type A personalities,
in which the organs, glands and systems of the sympathetic branch are stronger.
They have a rapid metabolism. Parasympathetic primary people are more
relaxed, easy going and tend to be right-brained. The organs, glands and systems
of the parasympathetic branch are stronger and they have a slower metabolism.
