SFTT | Anodal tDCS | Sham tDCS | Anodal tDCS | Sham tDCS |
1 | 408 ± 252 (n = 13) | 481 ± 268 (n = 16) | 20.8 ± 20.9 (n = 13) | 22.9 ± 23.5 (n = 16) |
2 | 354 ± 416 (n = 13) | 415 ± 320 (n = 16) | 10.2 ± 8.20 (n = 13) | 16.5 ± 21.4 (n = 16) |
3 | 226 ± 153 (n = 8) | 577 ± 394 (n = 13) | 7.38 ± 5.34 (n = 8) | 34.2 ± 28.7 (n = 13) |
Values are means ± SDs (number of participants). Total energy intake and candy consumption during the SFTTs for baseline assessment (SFTT1, on day 7), on the last day of the inpatient period (SFTT2, on day 11), and on the last day of the study (i.e., the last day of the outpatient visits; SFTT3). Total energy intake (kilocalories) and candy consumed (grams) on SFTT3, relative to SFTT1 and compared with the sham group, were significantly lower in the anodal tDCS group, as assessed with ANCOVA (P = 0.01; β: −376 kcal; 95% CI: 92.0, 661 kcal; df: 1; t value: 2.77; and P = 0.01; β: −28.6 g; 95% CI: 8.33, 48.8 g; df: 1; t value: 2.95, respectively). In a mixed model, the time-by-treatment interaction for total energy intake and for candy consumed is P = 0.05. SFTT, snack food taste test; tDCS, transcranial direct current stimulation.
