Lifestyle Changes Through Exercise and Nutrition

The LEAN Project is a community-based weight loss program that is delivered through churches
serving lower-income, obese, African American adults. The intervention will involve training
community health coaches to deliver the intervention. These community health coaches will be
individuals who are members of the church and who are willing to be trained on how to deliver
behaviorally-based, empirically proven, lifestyle change interventions. These community
health coaches will be trained by the staff at Pennington Biomedical, who have experience
training and delivering these types of interventions. The community health coaches will
deliver the intervention through their respective church after being trained. Weekly text
messages will be sent to participants in order to supplement the intervention sessions and
provide support. The primary aim is to determine if the trained community health coach
church-based intervention will result in significant weight loss. Secondary aims will assess
blood glucose, cholesterol, physical activity, food intake, and weight related quality of
life.
