The purpose of this research study is to pilot test five different, group based and remotely delivered programs designed to support healthy eating and regular physical activity. Each group will contain information and support for healthy eating and physical activity. Groups may also include support to 1) eat with more awareness of hunger and fullness, 2) improve how people think and feel about their bodies, and/or 3) identify ways to be physically active that are more enjoyable. Each group will include a unique combination of these components and the goal is to assess overall satisfaction and engagement with each of the programs.

The goal of study is to conduct a Multiphase Optimization STrategy (MOST) Preparation phase study to combine and pilot test candidate components for a group-based, remotely delivered weight neutral/healthy lifestyle intervention. Potential treatment components will include the following existing, evidence-based interventions; (1) mindfulness-based eating awareness training , (2) body acceptance program , and (3) a tailored intervention to promote enjoyment of physical activity. Weight neutral components will complement a Core intervention of standardized education on healthy diet (emphasizing the Mediterranean diet) and Physical Activity Guidelines for Americans (i.e., aerobic activity, muscle strengthening). This phase of the science is focused on pilot testing to ensure the target sample can be recruited and and that the novel combinations of treatment components can be delivered as intended. To make strategic use of resources, a fractional factorial design will be used to pilot test five conditions: the Core intervention alone and all possible combinations of the Core intervention + two or more of the weight neutral components. Men and women (n=50) with BMI≥25kg/m2 will be recruited and randomized in small groups (n=10) to receive one of the five conditions held online (each 12 weeks in duration).

Inclusion Criteria:

• 18 years and older
• BMI between 25-40 (if BMI is between 25-30 then additional cardiometabolic risk factor must be present including hypertension, high cholesterol, prediabetes or type 2 diabetes)

Exclusion Criteria:

• current participation in a formal weight loss program
• current use of weight loss medication
• history of bariatric surgery
• physical condition that would limit the ability to engage in moderate intensity physical activity
• current pregnancy
• recent weight loss of 5% body weight
• condition that may interfere with ability to complete the study procedures

All de-identified and scored data used to investigate the study aims will be preserved and shared upon approved request.

Data will be made available at the time of associated publication or the end of the project funding period, whichever comes first. The data will be retained with the repository for approximately 3 years past the publication date of the primary aims to permit sufficient time for replication of fundings.

Data will be uploaded by the PI into a repository that will meet compliance for federally funded research. The PI has authority to grant or limit access to the data. Upon receipt of request for access, the PI and investigative team will review to determine if the proposed use is scientifically justified and appropriate. If so, access to data will be granted through the portal, in coordination with the PI's institutional compliance department for data sharing, for time-limited use with potential for extension upon receipt of signed agreement to terms of use.
