Okay... I am the OP so I have only been at this a month now.
This week I've been doing spiralized zucchini meals for fast days, again w/my berry dessert (one cup mixed berries, 2 tbsp whipped cream, 1 tbsp mini choc chips). Here are two recipes I did on fast days this week and really enjoyed:

For non-fast days, it's harder to say. Since there are no rules about it, I just eat whatever I want. I almost always have pumpkin overnight oats for breakfast.

Lunch might be salad & bowl of soup, or rice and some sort of bean. This week we had a little more time to cook, so we made some fantastic barbecue chicken and slaw from scratch the other night.
Because I do have a sweet tooth, I always have some treat on non-fast days - a cookie, cupcake, ice cream. I am trying to curb this habit though and eat more fruit as a sweet ending when I need one. So far, I haven't been able to.
Another con of this diet though is that I find it harder to eat leftovers... I have never minded eating food the next day, but when you get two days down the road for some things, it's not as great anymore! So I have to be more careful about how much I make, knowing I will only eat it for one meal (unless I know my husband will keep eating it, like some chili we made over the weekend).
Yet another thought to add: I do find that at least for a while, there IS a "binge" mentality for me on non-fast days. It's fading now, but definitely in the beginning I had this feeling that I needed to eat everything on non-fast days while I could! An example is my favorite Trader Joe's roasted veg pizza. I ate an entire one (750 calories) one night because I knew I could not have the one leftover piece the next day.
The science behind this claims that most people will eat about 110% of their usual intake on non-fast days, which averages out over the week to lower caloric intake. Sometimes it does not feel like it to me, but it must be working somehow since I've lost weight.
