Summary: Helpful for breathing, relaxation, exercising and calmness
Review: While I really don't think that everyone can lose weight JUST by breathing correctly, this book is valuable for teaching some very, very good techniques.Most people breath intercostally (via their rib muscles) and don't breathe through the diaphragm, that thin membrane-like muscle under the lungs. Singers, wind musicians, yoga students, dancers and athletes learn to drop that muscle down to expand the chest and take air deeply into the lungs. Air that goes deeply into the lungs cleanses the lungs and oxygenates more of the body. More oxygen means more burning of the metabolism, hence the premise of this book. While some of the exercises in Jumpstart Your Metabolism are a bit cutesy (chanting a mantra about your bikini, for example) they actually can help relax you, help you sleep better and even exercise more easily. I found that if I did some of the breathing with mouth closed, concentrating on every breath, I could do much more exercise with a lot less panting and discomfort. So my opinion is that, while I doubt that pounds will drop off with every breath you take, this book is quite helpful to practice breathing exercises that augment your exercise and relaxation routines. And certain of the exercises can help before public speaking or anytime you might feel nervous (like a job interview, for example.) I give 4 out of 5 stars because the cute stuff was a bit silly. The content, however, is good.
