Causes of Obesity.

The article looks at a report by David B. Allison, a professor of biostatistics at the School of Public Health in the University of Alabama at Birmingham, published in the "International Journal of Obesity" that lists 10 hypotheses that may have contributed to the increase in obesity. The factors include endocrine disruptors, not enough sleep, keeping the home or work environment the same temperature year round, and some pharmaceuticals such as contraceptives and antihistamines.
