I just listened to an interesting lecture by one Eric Berg D.C.. He is discussing the different body types and how they do or do not lose weight when dieting. One body type is the Adrenal Type (the other three are Ovary, Thyroid and Liver) and what caught my ear was a simple test to see how strong your adrenal glands are. If your adrenals are drained and depleted exercise actually is not a good way to lose weight, so it could be important to know your status.
All you have to do is stand in a dark room with a mirror and a flashlight. A person should shine the flashlight from the side in to the eye and watch the pupil. If the pupil initially constricts but then twitches open and closed your adrenals are in poor shape. If your pupil constricts and stays constricted that would indicate stronger adrenals. This should be done over a two minute period.
More and more it seems clear that body type and blood type are important to know as it could mean the difference between losing weight, having cellulite or not, dying young instead of living to a ripe old age and more generally living life to the fullest.
