Metabolic therapy was first initiated in the 1960s by a dentist named William Kelley. According to Kelley, metabolic type was based on the reaction of the sympathetic (fight) and parasympathetic (flight) systems. He deducted that each individual responds differently to stressful stimuli by fighting it head on or running from it, and this determined their metabolic type. William Wolcott, a nutritional consultant, continued Kelley’s work by developing a questionnaire for each person to assess their specific type. Maintaining certain food choices according to your metabolic type may aid in weight loss and possibly stave off some diseases. However, metabolic therapy is still looked at by some as unsubstantial. There are three types:
This type would be associated with a parasympathetic (flight) dominant person. Someone that is often nervous and unfocused, seemingly energetic but depleted inside. They possess an insatiable hunger leaning toward fatty, salt laden foods and are unable to get successful results from low calorie diet programs. The best food choices for a protein type would be protein. This would include meats, especially those high in purine, such as organ meats like liver. For vegetarians high protein choices would be soy, tofu, legumes (especially lentils), some cheese and dairy, quinoa, nuts and tempeh. Fats and oils also benefit the protein type, but be sure to choose the healthiest options.
Sympathetic (fight) dominant people are often carbohydrate types. Caffeine is a dependency and a sweet tooth is a constant. They can be described as overachievers who more often than not struggle with managing their weight as well as their weak appetite for healthy foods. Foods for the carb type are primarily opposite of the protein type, such as raw or lightly steamed vegetables, raw or frozen fruits, legumes, nuts and seeds and whole grains. Keep protein, high purine protein, fats and oils to a minimum.
Mixed metabolic types are usually in the best position, as they are not steered by their parasympathetic and/or sympathetic systems. Their appetite is fairly normal as they do not overdo salts or sweets. The only downside to being a mixed type is that they tend to be fatigued, anxious and nervous at times although this is nominal compared to the above types. Maintaining equal proportions of the above mentioned proteins and carbohydrates is best.
Test It With Care
Your body requires specific fuel to run properly, and it's very important for you to pick the right fuel. Dispensing the wrong fuel may not only slow down an engine, but in due time it may cause it to seize. Some believe that feeding the body the wrong nutrition according to the needs of their metabolic type can be attributed to a compromised system. As mentioned above, metabolic therapy has received a wide array of criticism. However, it does work for many people. If you decide to find your metabolic type, do so with a keen eye. Be mindful of any medical history that may impede your test, such as diabetes, irritable bowel syndrome and high blood pressure.
