Also, to echo something I said on another thread: I'm on my 2nd Whole30. The first one, I couldn't let go of tracking, and I tracked in a super detailed way. The Whole30 worked (I got the sleep benefits, my guts cleared up, I felt great physically for the most part, and I even lost some weight), but I was still worrying about food in a way that took up a lot of my time and I'm sure contributed to anxiety. This time, I'm just keeping a very simple log here on the forum -- just a list of what I eat at each meal. I'm about 8 days from the end, and I feel even better than I did last Whole30, and for the first time in YEARS, I have almost no anxiety about what I'm eating. I don't think about what to eat next. I don't worry that I ate too much or too little or the wrong thing. I'm not perfect every day (ie, sometimes I get slightly off template), but I feel confident that my days average out to eating really, really well.
Basically, I just want to reiterate: Trust the program. It's worth it.
