1

Between-sibling (normal-weight compared with overweight/obese) comparison with the use of a paired t test. *P < 0.05, **P < 0.01. EAH, eating in the absence of hunger; %COMPX, percentage compensation index.

2

Intraclass correlation (1-factor random, single measures).

3

Mean ± SEM (all such values).
