I do it. And it's working pretty well for me so far (I've been doing it for almost 5 weeks, I think).
I've tried it before but did it very wrong. I get in the habit of letting myself eat too far below my daily calories, and then I get really hungry and overeat. Bad, and due to a bit of laziness on my part. But if I make sure I get enough to eat, it's not a problem for me.
I do daily AND weekly calories. So I'll do so many days with X amount of calories, and then I get 1 or more days with Y amount of calories. For example, If I ate 1500 calories a day normally, and I wanted a day or two where I could eat more than that, I could cut that # by like 50 calories a day for 6 days, and on day 7 I'd have an extra 300 calories (1800 calories for that day). Or some variation of that - whatever works.
Maybe try it for a bit and see how it goes. But don't restrict or indulge too much (if you're anything like me, either can throw you off track). But try it and see if it helps with your date nights. It's a shame to not have those. Good luck!
