After being meat and dairy free for awhile my cravings changed. I guess our brains are plastic? I ate (and loved!) meat for 28 years, but today I don't even crave it, and can report I enjoy food just as much as I used to. If being plant-based required will-power, I don't think I'd be able to do it.
I think it's actually easier to go all the way, and avoid meat completely, than it is to cut back. If meat is a regular, if limited, part of your diet the craving never goes away.
