With Americans fatter and more malnourished than ever--almost two-thirds of the population is considered overweight or obese compared with 56 percent in the late 1980s and early 1990s, and people of color and the poor are the most obese of all--federal and university researchers and outreach workers from various anti-obesity organizations aim to make the public more mindful about its food consumption and the economic toll of being too big. Some 300,000 deaths per year can be attributed to obesity, and medical costs associated with obesity are estimated at $147 billion annually. As the obesity problem grows, researchers investigate all facets of this condition, including the numerous nuances associated with obesity--a chronic disease shaded by class, race, food cultures, nutritional mindsets, and household income.
