It doesn't affect me simply because the "Serves 2" packets are just enough calories for my own dinner. More times than not, when on a trek with a partner, we will each bring a "serves 2" packet and split each to add some variety...until that one trip when we both bring the same flavor!

The more trips I go on, the more I experiment with lighter alternatives for meals, but unfortunately the packs you speak of just wake up my appetite, without bedding her back down.
