Mariah Carey has lost the baby weight and is flaunting a newly toned body on the cover of US Weekly today. Carey told the magazine that she had gained 70 pounds, an "enormous amount of weight." She decided to start working with Jenny Craig after she started feeling "trapped in her body," because she couldn't move. So just how did Carey get in shape so quickly? Read on to find out!

1. She met with a nutritionist. As part of the Jenny Craig program, Carey says she met with a nutritionist to decide how many calories she should be eating per day and stuck to a 1,500 calorie diet. She also made sure to eat small meals every few hours.

2. She worked out three times per week. Because Carey had a cesarean section, initially exercise wasn't a part of her regime. "Diet was 90 percent of it," she told Rosie O'Donnell on the The Rosie Show. But once she was able to add exercise back into her schedule, she started taking long walks with her dogs. Carey has long been a fan of water workouts, so we're not surprised to hear her say that she also started working out in the ocean to help lose her baby weight.

3. She didn't weigh herself. Instead of going by the scale, Carey says she would go by how things felt. "Does this dress fit better than it did three years ago? Then I'd be like, 'Ok, I'm good!'" she told Rosie.
