The investigators propose to conduct a randomized controlled trial with a wait-list control to determine efficacy in reducing risk of obesity and related disease in Native American employees of Twin Arrows Casino. Participants will be randomly assigned to the experimental group or the wait-list control. The experimental group will receive a 12-week mNDPR nutrition intervention with culturally relevant materials. Five NAU Masters of Public Health (MPH) students will be trained in Motivational Interviewing and the mNDPR nutrition protocol to serve as Lifestyle Coaches. These students will lead weekly, group-based coaching sessions with up to 15 participants each at Twin Arrows Casino. Participants will be assigned to their designated group based on their availability. The 12 weekly group sessions will be scheduled to accommodate various work shifts (day, night, and swing). The first group session will be 2-hours long to serve as an 'immersion', followed by weekly 1-hour sessions, all led by the Lifestyle Coaches. The Lifestyle Coaches will use Motivational Interviewing techniques to assist participants to develop personal goals. Lifestyle Coaches will also provide nutrition education, specifically using the mNDPR protocol. Participants in the wait-list control will receive the same intervention after the experimental group completes their 12-week intervention. In addition to measures at weeks 0 and 13, a 24-hour diet recall will be conducted in week 26 for the experimental group to explore long-term durability of diet quality changes.
