Mean (±SD) number of different non-nutrient-dense, energy-dense foods consumed, assessed by 24-h dietary recall (A) and during the previous 28 d (B) at 0, 6, 12, and 18 mo by intervention. In a mixed-factor ANOVA, significant (P < 0.01) interactions occurred with both methods of assessment; the Lifestyle+LV group (n = 101) consumed significantly fewer different foods than did the Lifestyle group (n = 101) at each time point (***P < 0.001 and **P < 0.01). LV, limited variety.
