Specific Aim 1 is to conduct a 3-4 month pilot study randomizing participants to two versions of a weight loss program. The program will be implemented in a convenience sample of overweight and obese adults living in Guinea-Bissau and measure changes in body weight loss (primary outcome), adherence to program recommendations including recommended food patterns, blood pressure, eating behavior, physical activity and mood (secondary outcomes). The data will be used to refine the weight loss program and conduct power calculations for a future trial.
