New Yorker Matt Diaz 'scared' about showing loose skin after losing 20 stone
Matt Diaz has lost nearly 20 stone (122kg) since 2009 but says he's "scared" about showing people his loose skin and stretch marks.
The New Yorker has posted a YouTube video in which he shows the world what he looks like for the first time.
"This is what 270 pounds of excess skin looks like, essentially," the writer and comedian says to the camera.
"I'm really scared to put this up because I'm scared people won't think I'm attractive any more."
The 22-year-old is raising money to have surgery on his chest, stomach and arms but says he also wants to promote body positivity.
Matt had a gastric band fitted aged 16 when he weighed 35 stone (225kg).
Six years later he's dropped to 15 stone (99kg) but says he still has lots of loose skin despite working out all the time.
"It's on my arms, my torso and there's nothing I can do about it... I've never shown anyone before," he says.
"I feel this all the time - whenever I sleep with someone new, whenever I'm somewhere... at a beach or something and I'm supposed to take my shirt off and I can't.
"I wanted to share this with you guys because I think it's important that I'm not ashamed about who I am, because I worked really hard to get here and I still don't have the body that I want. But I'm trying really hard to love myself.
"I'm really scared to put this up because this is who I am. And I worked so hard to lose all the weight... and I'm not going to be ashamed of who I am. Not any more.
"I can't preach body positivity and hide who I am."
Matt's funding page has now raised more than $50,000 (£33,500) so he can have skin removal surgery.
His original target was $20,000 (£13,400).
Matt says he wants to be proud of who he is but also wants other people with similar issues to be proud of themselves too.
"I work so hard to have a nice sense of style, to have a nice haircut and all that stuff because I want to own who I am.
"I want to control and like the things about myself that I can. But the things that you can't change or you can't fix you have to make peace with.
"I'm trying and that's why I'm showing all of you this.
"I have excess skin, I have stretch marks, I have a birth mark. I'm just a person and I believe that you should care for yourself.
"I'm not going to say that and hide who I am."
