This study, called the "Reducing Obesity Using Social Ties (ROBUST) Program," is testing a new way to help people lose weight. It's looking at whether including up to two friends, family members, or co-workers in a weight loss program helps the main participant lose more weight compared to someone who doesn't invite others. The study will compare a "Social Network Intervention" where you invite others, to an "Individual Lifestyle Intervention" which is a standard health coaching program. To join, you must be Black or Hispanic, 18 or older, have a BMI (Body Mass Index) over 30 kg/m2 (a measure of body fat), and be willing to use a food intake app. The study aims to see how many people attend coaching sessions and complete the study over 24 weeks.
