Since 1970, obesity rates in America have more than doubled. Currently, two-thirds (about 150 million) of adults in the United States are either overweight or obese (Food Research and Action Center). According to the American Journal of Clinical Nutrition, "overweight is defined as a body mass index (BMI) greater than 25, while obesity is defined as a BMI greater than 30." There are many factors that contribute to obesity, such as: biological, behavioral and cultural influences (Food Research and Action Center). Although these factors all play an important role in obesity, no factor is as influential as poverty. According to the American Psychological Association, “in 2010, the poverty line, or poverty line, was $22,314 for a family of four” (2). People living in poverty may be forced to rely on public assistance programs such as food stamps, or more formally known as the Supplemental Nutrition Assistance Program, or SNAP. On the surface, this program appears to benefit hungry families, but in reality, it facilitates their obesity. The previously mentioned family of four would qualify for a maximum of $688 per month in food stamps (North Carolina Department of Health and Human Services). That works out to just over $170 per week or $40 per family member. A paltry amount like this forces families to make difficult decisions about how much and what type of food they will provide for their family. Food stamps are not the only solution available; for example, a person may decide to find several jobs to supplement their income. However, multiple jobs lead to other triggers of obesity. Multiple jobs increase a person's stress level, which in turn increases paper density and energy costs. "The American Journal of Clinical Nutrition 79.1 (2004): 6-16. Web. October 22, 2013.
