Kim Kardashian's Flu Diet is Really Working Wonders on Her Body

Kim Kardashian made a joke about the flu helping her drop some poundage ... but these pics prove a little temp can do a body good.

Paps got Kim out and about in L.A. Tuesday night in a bralette, skin-tight pants and a very loose coat that let everything hang out. She looks good ... damn good.

That same night, Kim tweeted that she was 6 pounds down from the flu ... joking it made for an "amazing" diet. She took heat ... and then took the tweet down.
