The largest casual dining chain in the world, Applebee's, faces a class-action lawsuit after an E.W. Scripps media investigation found that it and other popular chain restaurants touted "healthy" dishes that actually contained far more calories and fat than the eateries claimed. The lawsuit was brought on behalf of every person who has eaten from Applebee's Weight Watchers Menu over the last four years, said Tara Kelly, one of the lawyers in the lawsuit.  The lawsuit was based on an E.W. Scripps investigation which found that dishes sampled at some Applebee's, Taco Bell, and Chili's restaurants, among others, sometimes contained as much as twice the calories and eight times the fat that the restaurants claimed in their published nutrition information.
