Posh, like my mama, doesn't drink water! I think this is so strange. I taught myself to drink water in college, mostly because I was broke and couldn't afford Diet Coke every time I was thirsty. But it's also healthier.
Also, Posh apparently keeps her 24-inch waist by never eating full meals. She only eats snacks -- pretzels and soy beans. That sounds like a sad existence to me. If you're only going to eat snacks, go for ice cream and nuts.
