The overall model fit was highly significant, with F(6,14285) = 10,665.49, p < 0.001 and R 2 = 0.818 for WasteWg, and F(6,14319) = 880.43, p < 0.001 and R 2 = 0.269 for MealWg.

Most importantly, the Age × Sex interaction also failed to reach significance (F(5,14280) = 0.001, p = 1.000), indicating that portion sizes were distributed uniformly across demographic subgroups.
