You may be asked to complete a questionnaire about your health and diet, how much you drink and smoke, your lifestyle and any medication you are taking. The practitioner will look at your skin, eyes and nails, and question you about your mood and stress levels. He or she may diagnose you through hair, urine or blood tests, applied kinesiology or a Vega machine.
You will be asked to exclude from your diet tea, coffee, alcohol, and chocolate, salt and salted foods, red meat, sugar and saturated fats. You may be placed on an elimination diet to pinpoint any food allergies. Using information gained through diagnosis, the practitioner will devise a treatment tailor to your needs. He or she may recommend a diet rich in a particular nutrient, which may be supplemented with doses of that nutrient in the form of capsules, powders or liquids.
