Examining the pattern of new foods and beverages consumed during obesity treatment to inform strategies for self-monitoring intake

摘要

Maintaining dietary self-monitoring during obesity treatment may improve outcomes. As dietary variety is associated with energy intake, understanding the pattern of when new foods and beverages are consumed may assist with identifying when self-monitoring should occur. This study examined dietary variety (total number of differing foods and beverages consumed) from the first 40 days of self-monitoring records reporting?≥?3 eating occasions and >600?kcal/day from 60 adults (55.9?±?9.1?yrs, 35.1?±?5.3?kg/m2, 80.0% female, 95.0% white) participating in a smartphone-based, lifestyle intervention. Dietary variety was coded using an ingredient-based approach. Additionally, new flavors of previously consumed items, and modified and non-modified items contributed to variety. Total number of different foods and beverages consumed over 40 coded days (cumulative variety [cv40]); number of days to reach 50%, 75%, and 100% of cv40; cv40by eating occasions; and mean number of new items consumed on weekdays and weekend days were calculated. CV40was 145.4?±?33.5. Number of coded days to consume 50%, 75%, and 100% of cv40was 12.7, 25.1, and 40.0, respectively. Dinner was greater (p?
