"We've heard from our community that listing "feeling fat" as an option for status updates could reinforce negative body image, particularly for people struggling with eating disorders. So we're going to remove "feeling fat" from the list of options. We'll continue to listen to feedback as we think about ways to help people express themselves on Facebook," it said on the petition's page.
However, while the emoticon itself is now not available on Facebook, users however, can still type in the word "fat" as a 'feeling' on Facebook, and select an emoticon to go with it.
Weingarten told CNBC via email that she felt "so happy" and could "literally not have stopped smiling since I found out Tuesday morning about Facebook's incredible and thoughtful decision to remove the emoticon."
"For me this petition feels like a wakeup call to everyone, that you don't have to fall into that trap. Overall, I am pretty shocked and excited by the fact that Facebook and the media were taken by this story and that they believe that eating disorder awareness and body shaming are issues that are worth being discussed and seen in new ways," Weingarten added.
