Cranberry "diet"

[JaW]

Okay, well my girlfriend told me she is starting a new "diet" I can sum up the entire diet in onesentence. Drink cranberry juice for 72. Thats all I kinda of flipped out I told her how unhealthy it was and how I think its a bad idea, she didn't listen to me. How bad is this? Three days on just cranberry juice? I mean doesn't sound healthy I know people fast and junk but err, could someone tell me any negative aspects of her doing this so I can tell her. Or if it isn't that unhealthy tell me why..

Any diet that restricts protein, complex carbs is bad. And cranberry juice has sugar. She will lose the weight but it will come back when she goes back to getting calories. Telling her that might stop her from doing it. Educate her on having a healthy diet and lifestyle and she can leave fad diets behind her.
