Morphology
The sense 'to gain weight' is a metaphorical extension of 'pack' (to put/accumulate) with the particle 'on' signalling addition; the parts suggest an increase but do not literally describe gaining body mass. A B1 learner who knows both words and sees the weight context can often infer the meaning, but the phrasal-verb use is idiomatic enough that it is not fully predictable without exposure.
Etymology
Pack on comes from the picture of adding things on top of a pile: to pack extra items on makes the pile bigger. So when someone adds body weight, we say they 'pack on' pounds, meaning 'to gain weight'.
