Intervention participants markedly increased fruit and vegetable intake while reducing energy intake from fat. Participants were 2,718 breast cancer survivors, aged 26-74 yr, with baseline mean body mass index of 27.3 kg\/m(2) (SD = 6.3). We assessed dietary intake by sets of four 24-h dietary recalls and validated with plasma carotenoid concentrations. Weight and height were measured at baseline, 1 yr, and 4 yr. Dietary energy density was calculated using food but excluding beverages. Intervention participants significantly reduced dietary energy density compared to controls and maintained it over 4 yr &#8212; both in cross-sectional (P &lt; 0.0001) and longitudinal (Group x Time interaction, P &lt; 0.0001) analyses. Total energy intake or physical activity did not vary between groups. The intervention group had a small but significant weight loss at 1 yr (Group x Time interaction, P &lt; 0.0001), but no between-group weight difference was observed at 4 yr. Our study showed that reducing dietary energy density did not result in a reduction in total energy intake and suggests that this strategy alone is not sufficient to promote long-term weight loss in a free-living population.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-45284","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Cancer Prevention and
