Metabolic Typing: The Key To Improving Metabolism

Metabolic Typing is the science of discovering the fundamental way in which your body produces energy from your food, in other words, the explanation of why “one person’s medicine is another’s poison.”

One of the basic principles of Metabolic Typing is that proteincarbohydratesfats,vitamins and minerals, which are transported by the blood, are best absorbed and utilized by the cells in your body at the ideal blood pH level of 7.46. Below this figure the blood is too acidic, above this figure the blood is too alkaline. The more your pH deviates from the ideal, the less efficient will be the conversion of food to energy.

The second principle of Metabolic Typing is that any nutrient can be acidifying or alkalizing, stimulating or inhibiting, depending on yourmetabolic type.

The benefits of eating according to your metabolic type are not justweight loss. Metabolic Typing is used by healthcare practitioners to help many conditions, including the following: weight problems, chronic fatigue, allergies, chronic pain, diabetesheart disease, and rheumatologic disease, just to name a few.


Determining  individual metabolic type:

These variables are analyzed to determine your individual metabolic type:

  1. Oxidative Rate- This is generally the most important dominant variable. This tells us how quickly or slowly you metabolize (or oxidize) food. A modified glucose tolerance test is done. After fasting for 12-15 hours, you will be given 50 grams of carbohydrate in the form of a fruit drink. Your blood sugars are then taken with a fingerstick test every half-hour for ninety minutes. The extremes of oxidative rates are seen in diabetes (slow oxidizer) and hypoglycemia (fast oxidizer).

  2. Blood, Urine, and Saliva pH– Protein, carbohydrates, fats, vitamins and minerals,  are transported by the blood, are best absorbed and utilized by the cells in your body at the ideal blood pH level of 7.46. Below this figure the blood is too acidic, above this figure the blood is too alkaline. The more your pH deviates from the ideal, the less efficient will be the conversion of food to energy. A reduced ability to feed the body on a cellular level causes cascading imbalances and eventually an breakdown that a doctor can hang a diagnosis on. The hip bone is indeed connected to the thigh bone.

  3. Autonomic Nervous System Dominance–  The ANS is the part of the nervous system that controls everything that occurs automatically, from blood pressure and blood flow to breathing and blinking. For instance, you do not tell yourself to breathe or increase your heart rate during exercise. Your body just performs these functions automatically. The extremes of ANS dominance are the Type A personality who is always on the go (sympathetic or adrenaline dominant) versus the Type B personality, laid back person who needs a boost to get them out of bed (parasympathetic or acetyl-choline dominant).

  4. Blood Type -Most people know the importance of blood typing with regards to receiving a blood transfusion. Likewise, foods can cause agglutination because of the presence of lectins on their cell surfaces. Lectins are sugar-binding proteins that agglutinate or clump cells. Foods contain different lectins. Your blood type will help determine what foods may not be beneficial for you because of lectin incompatibility. This is usually the variable responsible for not being able to eat certain foods that might otherwise be considered very healthy.

  5. Body Type -Body Type refers to where you tend to gain weight. Certain hormone systems are considered dominant depending on your Body Type. The four Body Types are classified as gonad, thyroid, adrenal, or pituitary. This is the reason why some people gain weightin the hips, while others are extremely skinny, but have that little pouch around the middle. Sometimes Body Type can be determined just by appearance. For example:


    Area of Weight Gain

    Body Type





    All over athletic build


    “Baby fat”



  1. Candida Infection – Candida fungus is present in soil, therefore it is on the food that is eaten every day. When you take an antibiotic, not only are the bad bacteria destroyed, but the good bacteria in the intestines that protect you from candida infections are also destroyed. This is why so many people have candida infections. This is often why so many people have candida infections. This is often the first condition that needs to be corrected when trying to regain your health. Candida or fungus feeds on sugar and simple carbohydrates. For this reason, people with this condition often have uncontrollable cravings forsugar and carbohydrates. Therefore it is imperative that the “food source” for the candida is limited in order to get rid of the condition. Presence of candida is determined by a blood test.

How many metabolic types are found among people? The number ranges from two to ten types. The most commonly used theory among researchers, however, is that there are three metabolic types: slow, fast, and mixed.

Define your own metabolic type using the questionnaire in the Table below . Highlight the characteristics that fit you most closely and count the total score under each column. With any particular entry, if you fall between fast and slow metabolism, highlight both. In choosing the answers, keep in mind that you are assessing your current actual condition, not a past or desired one.

Total score:

Total score:


Add the two totals, subtract the lower score from the higher one; then divide the result by the number of questions answered and multiply by 100 percent. If the result is less than 33 percent, your metabolism is moderate, if you come up with more, it is either fast or slow, depending on which score was higher.
