When Nicole Richie was pregnant she has gained some weight, looked healthy and was at an estimated 130 pounds. Now that she has given birth, she wants to lose weight. Nothing wrong with that, right? How much weight does she want to lose? Now that is the problem.

Allegedly, Nicole is planning to lose 20 pounds! Oh, and according to the rumors, she wants to lose 20 pounds fast, really fast. I do not actually believe this, but according to the sources, Nicole want to lose 20 pounds in 20 days, and that is just insane.

An obvious question here is, why, why on God’s green Earth would she want to lose so much weight so quickly? Well, if you can believe it, a source says that Joel Madden is attracted to anorexic chicks super-skinny women, and Nicole thinks that he would be happy to see her skinny again.

Nicole Richie’s post-pregnancy diet Nicole’s extreme diet is calling for a secret plan of attack. “She’s very sneaky about it – she’s cut her calories way down from when she was pregnant,” says the insider. “She consumes only chicken broth for long stretches of time. Instead, she should be reaching her ideal weight by eating a variety of healthy foods.”

When she does eat a full meal, she often opts for the worst choices (at a recent party, she reportedly scarfed down macaroni and cheese, steak and cake). While her healthy appetite seemed to temporarily dispel rumors of a new eating disorder, not everyone was fooled.

“Nicole’s problem is that she loves greasy junk food,” says the insider. “When she slips up and eats high-calorie things, she then starves herself as punishment.” [source: Star]
