Morphology

stick + to + one + diet

The meaning 'to continue following a diet plan' is directly derivable from the constituents: 'stick' (to persist or remain), the preposition 'to', and 'one's diet' (the person's eating plan). The phrasal pattern 'stick to' meaning 'adhere to' is common and cross-linguistically transparent, so a B1 learner who knows the words can infer the MWE's meaning.

Etymology

The phrase stick to one's diet comes from the image of something covered in glue that will not move. So, if something sticks to a surface it stays there, and to stick to one's diet means to 'keep following' the diet and not change it.
