3.2.1. External Eating

Regarding the first hierarchical multiple regression model, sex and age explained 5% of the variance of external eating, which did not reach statistical significance: *F* (2, 50) = 1.32, *p* = 0.277, *R*<sup>2</sup> = 0.050. After entering ghrelin, IR, and leptin/adiponectin ratio at Block 2, the total model did not statistically significantly explain external eating: *F* (5, 47) = 1.25, *p* = 0.303, *R*<sup>2</sup> = 0.117. Table 2 shows the regression coefficients of the independent variables on external eating.
