This is the first book on Behavioral Kinesiology written for both the layperson and the professional. According to this new science, ordinary, everyday things like the food we eat, the clothes we wear, the thoughts that go through our heads, even the music we listen to and pictures we look at have strengthening or weakening effect on our body muscles. This is not mere speculation. It has been demonstrated in the laboratory with of subjects. Now you can prove it for yourself by a simple muscle test. And although the demonstration is amazing and fun, it is far more than that 0 it is a valuable therapeutic tool. By means of this test, so easy to perform, you can actually ask your body will give you the answers. Now the old, familiar rules of health - good nutrition, good posture, comfortable clothes, a positive mental outlook - take on a new significance. This book, then, will give you a simple tool to determine the extent to which factors in your environment or in your life-style ae affecting your body energy. It will suggest many energy-enriching activities you can substitute for energy-depleting ones. And it will show you how to modify or counteract the effect of those debilitating factors that cannot be entirely eliminated. Behavioral Kinesiology is Dr. John Diamond's personal synthesis of developments in psychiatry, preventative medicine, kinesiology, nutrition, music therapy, and several other areas. Central to BK is the role of the thymus gland in regulating body energy, a role only recently understood.
