My family went through reducing our meat intake to a few days, and honestly - it kinda sucked, since it reduced many of our meal options, since they "had" to be vegetarian.

After about twelve months of this and getting sick of it, we settled on meals that usually have meat, but using less of it. For example; Pad Thai usually calls for mostly animal protein + noodles + tofu, so we usually pad it out with lots more vegetables, which is healthier anyway.
