Please don't get hung up on calories if it means your body isn't going to get all the nutrients it needs.
I've learned so much about food and eating in the last few weeks. Protein, fiber, carbs....there is so much to eat and enjoy without limiting yourself to calories. I've made a conscience decision to eat better, that includes more spinach, more chicken, more good fats. I snack on nuts and fruits. Those frozen meals just get so boring.
Good luck with whatever path you choose. Doing what you think might be most successful at is what is important.
