Celebrities are known for trying all sorts of crazy diets, but Mariah Carey’s takes the cake. (Don’t get too excited, cake is definitely not on the menu.) Carey told E! Newsshe eats salmon and capers—that’s it. “It’s really hard,” she said. “I try to stick with the proteins. It’s the worst. But it works!”

Um, OK, a few problems here. First off, most people aren’t going to stick to a diet they describe as “the worst.” Plus, a healthy diet should make you feel great, which is pretty hard when you hate what you’re eating every day.

Carey’s food choices are healthy—salmon is full of omega-3 fatty acids, which can reduce the risk of cardiovascular disease, and capers are naturally low in calories. But eating two foods all day, every day is a bad idea, no matter how healthy they are. You won’t get all the nutrients you need from eating fish and capers. Carey could at least add some fruits and veggies to the mix for a more balanced diet.
