It's no surprise that we have an obesity epidemic in America. Temptation to over-eat bombards us everywhere. This, combined with our sedentary lifestyles, has helped us pack on the pounds. Obesity also increases the risk of type II diabetes. Nearly two of three adult Americans are overweight or obese. Experts say patient education, along with advances in research about genetics, human physiology, plus effective medications and surgeries are making a huge difference in shrinking this growing epidemic.
