There's recipes for cucumber/lemon/ginger/cinnamon/whatever-infused water on pinterest telling you to drink x amount of it every day and you'll lose weight, and it's called skinny/detox/magic unicorn fart water. It's probably meant to be "drink this when you feel like snacking and with your meals so you still get to taste something but consume fewer calories and you'll lose weight" but I doubt she is doing that.
