If you want to diet like Gwyneth Paltrow, Reese Witherspoon and Jennifer Aniston allegedly do, start shopping in the baby food aisle. Yes, this fad diet (started by celebrity trainer Tracy Anderson) has adults chowing down on pureed fruits, vegetables and meats instead of foods that require, say, teeth to eat them.

The baby food diet uses jars of baby food as meal replacements; the idea is to substitute a jar of pureed food for each meal and snack, and the plan recommends eating 14 jars plus an optional adult-worthy dinner every day. (Yes, that's a lot of tiny meals and snacks throughout the day.) The problem, aside from flavor, is that baby food is for babies, not adults. Adults have different nutritional needs that can't be met with this quick-fix fad diet, and watch out -- baby food portions are very small, which can lead to overeating. And not all jarred baby food is low-calorie.
