BIOL 225 - Science Behind Obesity

In 2003, the Surgeon General declared obesity as an epidemic. Today, approximately 61% of Americans are now overweight, of which 20% are obese, and health related issues to this condition for 5% of the national health care costs. But, why are we getting fatter? In this course, we will explore the science behind obesity to become familiar with the impact that this health issue has on the human body. In particular, we will look at how fat is stored within the body and the consequent cellular, metabolic, tissue and endocrine changes that occur. We will review various studies looking at human and animal fat use and storage, examine fat deposition, metabolism in men and women, chronicle cultural differences in food procurement, preparation, and consumption, and consider the influence of sedentary occupations and lifestyles. We will also explore various obesity health related illnesses such as Type 2 (fat related) diabetes, stress, hypertension, increased cholesterol, infertility, heart disease, stroke, some types of cancer, arteriosclerosis, gallstones, osteoarthritis, back pain, endocrine disorders, and even the need for transplants.
