Ian Craig on eating for your biotype
Biotype has to do with the dominant glandular systems in the such as thyroid, adrenal and pituitary etc. Thyroid dominant biotype tends to burn out their adrenals easier due to their fast metabolism. The adrenal type tends to burn out the thyroid more and then have problems with weight. It is useful to find out what type a person is to get a clearer understanding as a whole and optimize treatment.
