Morphology
fill + up
The meaning 'to eat until one is completely full' is directly derived from 'fill' (to make full) combined with the particle 'up', which signals completion or fullness. This compositional completion pattern is common in English and other languages, so a B1 learner who knows both constituents would readily infer the MWE meaning.
Etymology
The phrase fill up comes from the image of a stomach or plate being filled until there is no space left. That is why we say someone 'filled up' when they have eaten enough to be 'full'.
