This document is not based on experiential evidence. It's based on scientific research evidence including systematic reviews, meta-analyses, randomized controlled trials (like SMILES, HELFIMED, AMMEND studies), observational studies, and clinical guidelines. The authors conducted a comprehensive literature review of peer-reviewed research to inform their policy recommendations.

This document incorporates some practice wisdom through expert reviewer input from practicing dietitians, psychologists, and lifestyle medicine practitioners. However, it's primarily evidence-based research rather than practice wisdom. The authors acknowledge practitioner barriers like low confidence in nutrition counseling and knowledge gaps, but rely on scientific studies for recommendations.

This document is heavily based on research and evaluation insights. It cites extensive peer-reviewed research including systematic reviews, meta-analyses, randomized controlled trials (SMILES, HELFIMED, AMMEND), observational studies, and evaluations of existing programs like the Better Access Initiative. The policy recommendations are grounded in rigorous scientific evidence and program evaluations.
