"You all know I’ve been on this journey for most of my life," she told those in attendance. "My highest weight was 237 lbs. I don’t know if there is another public person whose weight struggle has been exploited as much as mine over the years." "You all have watched me diet and diet and diet," she continued, before noting that it's "a recurring thing because my body always seems to want to go back to a certain weight."

"This is a world that has shamed people for being overweight forever. And all of us who’ve lived it know that people treat you differently, they just do," she said. The former talk show host then explained that she found she dealt with that stigma the most while out clothes shopping. "It’s that thing where people are like, 'Let me show you the gloves. Would you like to look at the handbags? Because we know that there’s nothing in here for you,' " she said. "There is a condescension. There is stigma."'
