Many celebrities have lost their pregnancy weight (e.g. Britney Spears and Katie Holmes, Leah Remini, and Geri Halliwell) without anyone ever finding out what it takes. First of all, you simply cannot continue to eat as much as before. Two, exercise and diets are to be highly customized to your body; in other words, you might need help of a personal trainer.

Even celebrities have to work hard to get rid of the extra pounds. Gwen Stefani tells Harper's Bazaar, "It's so much work afterward to get the weight off...If you just do it, it comes off. And when you're nursing, like I am, your metabolism is like whoosh!"

Tori Spelling, who gained 40 lbs. has joined the NutriSystem food-delivery program to achieve her pre-pregnancy body. I think if Tara Reid can do it, anyone can. Alternatively, she can have a mommy makeover.
