Points or core?

Good luck with it! I have always had more success with counting points than with core, mostly because I am really dependent on processed convenience foods that are not on core. I recommend getting a digital food scale if you don't already have one, and weigh or measure everything to start, until you get a handle on what a real-sized portion is supposed to look like. And then keep weighing/measuring after that, because otherwise they tend to grow on you!
