TABLE 2.
Continuous glucose monitoring indices during 1 wk of habitual diet (pre) and during 2 wk of eTRF or CON:CR1
| Characteristic | Pre-CON:CR | Pre-eTRF | During CON:CR | During eTRF |
|---|---|---|---|---|
| Mean glucose, mmol·L−1 | ||||
| 08:00 to 20:00 | 5.58 ± 0.14 | 5.49 ± 0.19 | 5.53 ± 0.09 | 5.75 ± 0.13 |
| 20:00 to 08:00 | 5.34 ± 0.16 | 4.93 ± 0.18* | 5.33 ± 0.07 | 4.58 ± 0.12*** |
| Glucose variability, %CV | ||||
| 08:00 to 20:00 | 13.6 ± 1.1 | 17.8 ± 0.7** | 14.2 ± 1.2 | 18.6 ± 1.1** |
| 20:00 to 08:00 | 13.9 ± 1.0 | 16.7 ± 1.4 | 14.0 ± 0.8 | 13.5 ± 1.4 |
1Data are means ± SEMs; n = 8 for both CON:CR and eTRF. Separate mixed-design 2-factor ANOVA was performed for the 08:00 to 20:00 and 20:00 to 08:00 time windows that were not directly compared. The analysis revealed an intervention (group) effect (P = 0.003) between CON:CR and eTRF for mean glucose during 20:00 to 08:00 only (post hoc: *P = 0.02 and ***P = 0.001 from corresponding CON:CR) and an intervention effect (P = 0.003) between CON:CR and eTRF for %CV during 08:00 to 20:00 only (post hoc: **P = 0.01 from corresponding CON:CR). CON:CR, control/caloric restriction; eTRF, early time-restricted feeding.
