My lady and I have been considering meal replacement and were asking ourselves the same question of whether or not we wanted high cal or just vitamin. I'm thinking just vitamin with a couple of hundred calories, because if I'm keeping my weight or adding weight, the unprepared and hungry neighbors are going to get suspicious and GOD knows that no matter how prepared we are, we can't feed all our neighbors, their families, extended families and whomever else they've decided to tell. Gotta hide it, or in my opinion, we risk losing it.
Make em sharp and shoot em straight, or leave em home.
