Presumably the same way your body regenerates; his is just faster. And IIRC, he has to eat a lot after sustaining an injury to get what his body needs.
It’s sadly more stupid than that. His eyes open a portal to another dimension, although that’s been retconned and apparently now they “metabolize the suns energy”
Does he have to eat lots to power the laser
you can’t make sense of X-Men in terms of physics. Where does Wolverine’s body regenerates from? meat dimension
