"MyPlan" - Individualized Eating Pattern
All youth enrolled in the study will receive the 6-month MyPlan behavioral intervention. Youth will be paired with a dietitian to individualize the eating plan and receive support in setting and refining action plans focused on adhering to the five eating behavior goals that define the eating plan. "MyPlan" - Individualized Eating Pattern: Sessions involve a structured behavior change counseling module derived from FLEX (NCT01286350), DASH-4-Teens (NCT00585832), and a Social Cognitive Theory and Transtheoretical Model informed conceptual framework, which uses education, motivation and self-efficacy enhancement, goal setting, and problem-solving skills training to initiate and sustain eating plan adherence. Sessions support incremental progress towards meeting all five eating behavior goals by helping youth develop action plans, troubleshoot barriers to adherence, and refine action plans to improve adherence. Youth log in MyFitnessPal three days per week. Logs are used to assess and troubleshoot adherence, support youth in developing and refining action plans, and reward youth with points. Incentives are allocated using a point scheme designed to promote logging and goal achievement. Formal adjustment of eating plan at three months is based on weight status, adherence according to logs, and youth/guardian acceptability.

Mean composite acceptability score (range: 5-20) calculated from Likert responses (1- Strongly Agree, 2- Agree, 3- Disagree, 4- Strongly Disagree) to 5 items from an instrument that captures ease of eating pattern adoption, satisfaction, food enjoyment, sustainability, and ease of blood sugar management as perceived by youth. Lower composite acceptability scores indicate greater acceptability (5 - highly acceptable 20 - highly unacceptable).
