Hollywood celebs like Lady Gaga, Jennifer Aniston, Reese Witherspoon and Cheryl Cole have reportedly used the baby food diet to slim down. Here's looking at the three craziest celeb diets. The Maple Syrup Diet Singer Beyonce used this diet to lose weight for her role in Dreamgirls. The Kids' Cutlery Diet According to actor Liz Hurley eating on a nursery plate using children's cutlery is a great way of reducing food intake as she believes it tricks her into thinking she's eating more than she really is. Also, when she is trying to lose weight, she restricts her food intake to just watercress soup. Raw Food Diet Actor Demi Moore swears by this diet; which even extends to raw meat.
