Individual behavior change lies at the inner core of the social-ecological model that forms the basis of the 2015 Dietary Guidelines Advisory Committee's conceptual model (see Scientific Report of the 2015 Dietary Guidelines Advisory Committee: Part B. Chapter 2: 2015 DGAC Themes and Recommendations: Integrating the Evidence). For this reason, it is crucial to identify the behavioral strategies that individuals living in the United States can follow to improve their dietary and healthy lifestyle behaviors, as well as the key contextual factors that facilitate the ability of individuals to consume healthy diets. Recognizing the importance of these dietary and lifestyle behaviors to the health and wellbeing of the US population, the Committee reviewed recent evidence to address questions on the relationship between eating out, family shared meals, sedentary behavior, and diet and weight outcomes. The 2015 Dietary Guidelines Advisory Committee also focused on identifying evidence that could provide individuals with tools to improve their dietary choices and body weight status. Specifically, the Committee reviewed recent evidence on the impact of diet and weight self-monitoring, and on the use of food and menu labels on dietary intake and weight outcomes. The Committee also focused on the association between diet, body weight, and chronic disease outcomes and two contextual factors that are highly relevant in the United States—household food insecurity and acculturation.
