I'm always hungry when I'm PMSing and when I'm ovulating. I eat an extra 200 calories these days and it hasn't hurt.
I get mad cravings for chocolate when I'm PMSing. But not any kind chocolate. I don't know what kind of chocolate I keep craving, it's pretty frustrating.
I actually googled it yesterday. I've read that you're supposed to eat a bit of dark chocolate to make the craving go away but I'm still side-eyeing that article. If you can limit it to one day during PMS just eat what you want. You won't die or undo all your work.
