Well, last night as I was going to bed, I thought, now wait a minute I did not try to "cheat" even once today. Not a single thought of something sweet or crunchy or carby. Now all my macros/calories were a tad high so some tweaking is in order. But it was a great first day!
Regarding specific vitamins. I think we get what we need when we eat whole foods. And learning to listen to our bodies will help us not only know when to eat but what to eat. If you are truly worried there are always supplements.
I can see both sides of the "to eat or not to eat" argument. I really do want to get to the point where body cues are what tell me what and when to eat. But I have had disordered eating for so long that going without eating sets up a binge, either because "I deserve it" since I have been doing so well, or because my body is literally starved for nutrients. But surely our ancient ancestors did not have access to food whenever they wanted it, so IF in some form is probably natural. Of course they did not likely have the same mental/emotional eating issues we tend to be faced with. Obviously an individual thing. But I think Paula's point that this is not about purposeful calorie cutting so much is a good one, at least in my situation.
