On a practical level cutting out meat entirely can actually increase emissions because you can raise farm animals off of human inedible parts of plants like stems and other marginal food (i.e. parts we don't get any nutrition from). Beef however is one of the worst conversion methods in this regard, but animals like chickens and goats are quite efficient.
Insects are most efficient btw, but there are cultural reservations about them in the west.
