J Lo: 50 lbs slimmer since giving birth

Pop sensation Jennifer Lopez recently revealed that she's lost 50 lbs since giving birth to twins Emme and Max six months ago, according to the latest issue of Woman's World Magazine.

How did she do it? Well, aside from working out regularly with her personal trainer, Jen apparently did what many celebs are doing these days -- she signed up for a food delivery service. Freshology offers a package specially designed for new mommies called Fresh Mommy. But before you start googling Freshology, consider this: The price for the service is about $450 a week.

Looking to lose the baby weight but can't afford that price tag? Calorie Lab has some tips on how you can imitate J-Lo's post pregnancy diet.
