This pilot study investigates the effects of a newly developed 12-week weight management program called "GameDay Ready" (compared to a walking and general health education program) for decreasing body weight among Black men who live in the rural South. The researchers expect to see evidence of greater weight loss among participants randomized to receive the "GameDay Ready" program.

GameDay Ready is a 12-week, group-based behavioral weight management program in which participants will meet in-person once per week at a publicly accessible walking track. The GameDay Ready program promotes increasing physical activity, reducing sedentary time, and improving dietary habits through education, behavioral self-monitoring, and goal setting. Each 60-minute intervention session includes a brief educational component followed by a group discussion of weekly progress. Following a short warmup walk, participants engage in group-based competitive physical activities and then a short cooldown walk. Participants then set individual and group-based goals for the upcoming week and discuss strategies for overcoming barriers to achieving goals. The program is sensitive to intersectional influences of gender, race, and rurality on health; and strategies to enhance motivation are threaded throughout the program.
Participants receiving the comparison program will complete a 12-week walking and general health education program. Group sessions meet once per week at a publicly accessible walking track, and each 60-minute session consists of a brief educational component on a health topic followed by walking and socializing during the remainder of the session.

RECRUITINGBody weight
Participants' body weight will be measured in pounds using a portable, professional-grade scale. Changes in body weight will be compared between the intervention and comparison programs.
Time frame: Baseline, post-intervention (12 weeks), and 3 months post-intervention
Body mass index (BMI)
Participants' body weight will be measured in pounds using a portable, professional-grade scale, and height will be measured using a portable, professional-grade stadiometer. BMI will be computed as weight (lb) / \[height (in)\]2 x 703. Changes in BMI will be compared between the intervention and comparison programs.
Time frame: Baseline, post-intervention (12 weeks), and 3 months post-intervention
Waist circumference (WC)
Participants' WC will be measured using anthropometric measuring tape. Changes in WC will be compared between the intervention and comparison programs.
Time frame: Baseline, post-intervention (12 weeks), and 3 months post-intervention
Blood pressure (BP)
Participants' systolic and diastolic BP will be measured using an automatic blood pressure machine. Changes in BP will be compared between the intervention and comparison programs.
Time frame: Baseline, post-intervention (12 weeks), and 3 months post-intervention
Moderate-to-vigorous physical activity (MVPA)
Average minutes of MVPA will be measured over 7 consecutive days using research-grade, wrist-worn accelerometers (ActiGraph). Changes in MVPA will be compared between the intervention and comparison programs.
Time frame: Baseline, post-intervention (12 weeks), and 3 months post-intervention

Fruit and vegetable consumption will be measured using the National Cancer Institute's Dietary Screener Questionnaire that was used in the 2009-2010 National Health and Nutrition Examination Survey. Changes in fruit and vegetable consumption will be compared between the intervention and comparison programs.
Time frame: Baseline, post-intervention (12 weeks), and 3 months post-intervention
Added sugar consumption
Added sugar consumption will be measured using the National Cancer Institute's Dietary Screener Questionnaire that was used in the 2009-2010 National Health and Nutrition Examination Survey. Changes in added sugar consumption will be compared between the intervention and comparison programs.
Time frame: Baseline, post-intervention (12 weeks), and 3 months post-intervention
Whole grain consumption
Whole grain consumption will be measured using the National Cancer Institute's Dietary Screener Questionnaire that was used in the 2009-2010 National Health and Nutrition Examination Survey. Changes in whole grain consumption will be compared between the intervention and comparison programs.
Time frame: Baseline, post-intervention (12 weeks), and 3 months post-intervention
Social support for exercise and diet
Social support for exercise and diet will be measured using validated scales developed by Sallis et al. Changes in social support for exercise and diet will be compared between the intervention and comparison programs.
Time frame: Baseline, post-intervention (12 weeks), and 3 months post-intervention
Perceived environmental support for physical activity
Perceived environmental support for physical activity will be measured using the 33-item Rural Active Living Perceived Environmental Support Scale. Changes in perceived environmental support for physical activity will be compared between the intervention and comparison programs.
Time frame: Baseline, post-intervention (12 weeks), and 3 months post-intervention
Motivation for weight loss
Motivation for weight loss will be measured using an 8-item Weight Control Motivation Scale. Changes in motivation for weight loss will be compared between the intervention and comparison programs.
Time frame: Baseline, post-intervention (12 weeks), and 3 months post-intervention
Motivation for healthy eating
Motivation for healthy eating will be measured using a 15-item scale of the Treatment Self-Regulation Questionnaire. Changes in motivation for healthy eating will be compared between the intervention and comparison programs.
Time frame: Baseline, post-intervention (12 weeks), and 3 months post-intervention
Motivation for physical activity
Motivation for physical activity will be measured using the 24-item Motivation for Exercise Scale. Changes in motivation for physical activity will be compared between the intervention and comparison programs.
Time frame: Baseline, post-intervention (12 weeks), and 3 months post-intervention
Exercise self-efficacy
Exercise self-efficacy will be measured using a 16-item Self-Efficacy for Exercise Scale. Changes in exercise self-efficacy will be compared between the intervention and comparison programs.
Time frame: Baseline, post-intervention (12 weeks), and 3 months post-intervention
Relatedness to others in physical activity
Relatedness to others in physical activity will be measured using a 6-item scale developed by Wilson \& Bengoechea. Changes in relatedness to others in physical activity will be compared between the intervention and comparison programs.
Time frame: Baseline, post-intervention (12 weeks), and 3 months post-intervention
Perceived stress
Perceived stress will be measured using the 10-item Perceived Stress Scale. Changes in perceived stress will be compared between the intervention and comparison programs.
