Could you stomach these diets?

Beyoncé, Gwenth Paltrow and Sarah Jessica Parker have deprived themselves of solid food for days on end in order to lose weight.

WOULD you deprive yourself of solid food for 10 days, consuming only a concoction of lemonade, maple syrup, water and cayenne pepper? Beyoncé did.

Mariah Carey opted for this.
