That's a very fair point, but it seemed like premature optimization to try to nail down a meal plan before all the kinks in the nutrition side of things were ironed out. I do plan on getting to that stage in a later version.
Perhaps I should have waited before publishing this post, but honestly, I tend to lose myself in projects like this, and without some indication that other people are interested I often end up leaving the work in an archive somewhere to finish later.
I hope that there's enough data there to be useful/interesting in its current state, but I agree, needs more work
