Maria Kang, the controversial online force also known as "Fit Mom," was temporarily kicked off Facebook last week after a fat-shaming rant.
Kang wrote a post about positive media coverage of an online group that's encouraging plus-size women to post photos of themselves in lingerie.
The group's goal is to show what "real women" look like.
Maria Kang, who caused controversy this year by posting a photo of her toned self with her kids and the tagline "What's Your excuse?" was not impressed.
Maria wrote on Facebook that she was "starting to get annoyed" at all the attention this was getting, then criticized the high obesity rates in the U.S.
"We keep blaming the culprit (school lunches, fast food) when real change starts at home," wrote Kang, upset that she, conversely, took heat for being so fit.
