Yes, but if you've never tried to be vegetarian before, then your fears of the downsides (bad health and not enjoying food, right?) might be out of proportion. Going fully vegetarian for a bit gives you a chance to get feedback from your body about it, and so help you determine your limit.

If you cut down your meat intake but stay high above the limit then you're causing some animal suffering for no significant gain. (I assume reducing animal suffering is the goal of your plan.)

I planned to this myself but I'm not doing it, because of issues with my SO.
