Table 3.

Comparison of sleep, food intake timing, dietary intake and energy distribution the weeks before the day of the experiment (habitual characteristics) between EE and LE eating conditions within each genotype group.

    Sleep offset (hh:mm) 7:58±1:01 7:47±1:00 0.302 7:34±0:40 7:43±0:37 0.227
    Sleep duration (hh:mm) 7:25±0:41 7:17±0:50 0.415 7:24±0:35 7:39±0:35 0.115
Timing of food intake
    Start breakfast (hh:mm) 8:43±0:53 8:48±0:47 0.330 8:41±0:56 8:42±0:54 0.783
    Start lunch (hh:mm) 14:40±0:20 14:46±0:24 0.346 14:31±0:51 14:45±0:23 0.284
    Start dinner (hh:mm) 21:31±0:33 21:35±0:33 0.566 21:33±0:24 21:27±0:26 0.169
Dietary Intake
    Total Energy Intake (Kcal/day) 1391±606 1332±260 0.703 1337±234 1466±74 0.090
Distribution of energy (day)
    Breakfast (%) 19±7 19±5 0.870 17±7 17±6 0.987
    Lunch (%) 39±10 37±7 0.561 42±11 41±11 0.753
    Dinner (%) 26±9 31±9 0.218 29±11 29±9 0.597

Distribution of the energy with respect of the total energy intake; the difference to 100% corresponds to inter-meal snacks consumption; EE (Early eating condition), LE (Late eating condition). Habitual P values indicate comparison between EE and LE as tested by paired Student’s t-test for each genotype group.
