In 2007, Lancaster General Health created the Lighten Up Lancaster County coalition to raise awareness about the health problems associated with poor nutrition, lack of physical activity, and obesity. Recognizing that obesity is a multi-faceted problem, the coalition brought together health care providers, schools, businesses, community organizations, and local government to create multi-faceted solutions. When the coalition began, we focused on educating the public about healthy eating and physical activity and creating high-quality programs to help people reach a healthy weight. Over time, the coalition has become more involved in creating policies, systems, and an environment that supports a culture of health. Currently, our priorities are building walkable & bikeable communities, improving school and workplace wellness programs, and increasing access to healthy food.
