This study investigates two different strategies to see which one is more effective in lowering Body Mass Index (BMI) and improving how the body processes sugar. The strategies being compared are the Health Education and Coaching Strategy and the Dietary Consult Strategy. BMI is a measure that uses height and weight to estimate body fat, and it helps in understanding health risks related to weight.

Participants in the study will engage in specific procedures related to the strategy they are assigned to. The Health Education and Coaching Strategy involves learning and receiving guidance on health-related topics, while the Dietary Consult Strategy focuses on dietary advice and planning. Both strategies aim to support better health outcomes by managing weight and sugar levels in the body.

• Who can participate: This study is open to individuals who are in Tanner Stage II-V, are overweight or obese, and have a family history of type 2 diabetes or a diagnosis of type 1 or type 2 diabetes mellitus. Participants should not be enrolled in a weight management program.
• Study details: Participants will be involved in activities based on the strategy they are assigned to, either receiving health education and coaching or dietary consultations. These activities are designed to help manage weight and improve sugar levels.
