Lady Gaga is not only speaking out against the critics who have publically scrutinized her apparent weight gain, she is also taking action, and not surprisingly, it's working. Earlier this week, Gaga launched the "Body Revolution 2013" campaign, a new section of her Born This Way Foundation, which encourages her little monsters to stand against discrimination and to accept the person they are.

Gaga kick-started the initiative on her Little Monsters site with four revealing photos of herself in just a bra and underwear, admitting her insecurities and that she suffered from bulimia and anorexia since she was 15.

"We've had literally thousands of submission to BODY REVOLUTION 2013 on littlemonsters.com ," Gaga tweeted on Wednesday. "I'd like to give you applause, so happy."

Fans instantly responded to Gaga's message to "inspire bravery. and BREED some m$therf---ing COMPASSION," but also found strength in the photos that Lady Gaga shared. One commenter, Ida, posted that she to struggles with the same issues that Gaga does every day.

"I can't stop crying. Gaga i'm battling the same thing right now; you met me in [Sydney] the first thing you said to me was 'Oh my God you're so skinny' And from then on i've been trying to recover so much but it's been killing me," she said. "i've been relapsing a lot lately and all i do iscry about my body and i feel like i wish i never did recover but this. looking at this is making me strong. You inspire me. If you can be strong, i can too. Thankyou for helping me. TYhankyou for everything."

Another reader told Gaga, "LOVE YOU. I have struggled with weight and eating issues my whole life. Your honesty and bravery make is better and for all of us. You are beautiful -- today, yesterday and tomorrow."

Yet, fans are also finding the "Body Revolution 2013" an outlet where they can easily share in their own personal struggles and find support. One fan, who posted a photo of herself in just a bra said, "I've NEVER posted a picture of by body online, even fully clothed. I've been so ashamed all my life. But Gaga, and you little monsters, have made me brave. Thankyou all so much for giving me enough confidence to post this."

Another little monster uploaded a photo of herself in a wheel chair, "My body revolution. 1 and 1/2 legs and proud of it. Gaga makes me stronger than I thought I could ever be."

In response, one fan said, "Wow you are so beautiful! And your smile is gorgeous, you are fabulous and keep staying strong."

Another Gaga supporter, Leonardo Battani, posted a photo of just his hand stating, " I was born with genetic malformations on the left hand and left chest, my dream is to play piano as f---ing well as Gaga, it's hard, but I will make it!!"

Fans quickly responded, with one saying, "And you'll post a video of you playing piano so we can see how talented your are. Talented and combative. You're grazing perfection you Monster!"

It seems like Lady Gaga is well on her way to starting a positive and effective movement.
