| Purging type AN (n = 10) | Restricting type AN (n = 20) | Atypical AN (n = 9) | |
| Number of steps per day | r = −0.055; p = 0.865 | r = −0.465; p = 0.039* | r = 0.283; p = 0.434 |

AN, anorexia nervosa; EAT, exercise activity thermogenesis; MET, metabolic equivalent; NEAT, non-exercise activity thermogenesis; REE, resting energy expenditure; TEE, total energy expenditure. Values for r and p are indicated in each row, *p < 0.05.
