Yeah, I see a lot of complications involving iron, b12, and a few other things.
I don't have some sort of moral absolute thing going on; I ought to be able to make a low-effort glance into the things I eat and pick a diet that closely matches my intuitions without sacrificing health, happiness, or undue money. Like if it turns out that beef is the most ethical meat, and that eggs are really horrible, then I might eat beef but not eggs, if they are just vastly better ways of getting things that are otherwise a complete PITA to acquire.
Most likely, though, I can get by with very minimal tradeoffs, or at least it looks that way.
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.
