About Dr. Chang

Henry K. Chang, M.D. is an internist who has practiced medicine in Carmichael, California since 1976. He has treated tens of thousands of patients over this period of time. As a passionate proponent of exercise, good nutrition and prevention of disease, Dr. Chang has created a revolutionary weight loss method incorporating—yes, a simple five-second daily routine. After developing and applying his innovative method, Dr. Chang has had unparalleled success: a whopping 93% of his patients have lost weight—and are keeping it off!

This book is based upon Dr. Chang’s original study of 140 patients who followed his new, simple weight loss plan and achieved dramatic results. Thrilled with his patients’ success, he couldn’t wait any longer. He knew his break-through method must be shared with others who are struggling with excessive weight. So he wrote this book.
