At the age of 16, Matt Diaz decided he needed to lose weight. Six years later, he's lost around 270 pounds.
But after working hard to reach his goal weight, the 22-year-old has been left with excess skin.
"I'm a big advocate for body positivity, but I've never shown what my excess skin looks like," he says in the video above.
"I think it's important that I do, because I want to be open with new people about who I am and what my body is like.
"I've never done this before and I'm really, really scared, so don't judge too much."
The writer and comedian uploaded the brave video to YouTube on Wednesday. It's already gained over 9,000 views.
He explains that loose skin covers his whole body, but it is most noticeable on his chest and stomach area.
He has a birth mark on his side, which has also stretched due to his weight problems as a teen.
"I work really hard and there's just nothing I can do about it," he explains. "I'm scared people won't find me attractive anymore.
"I feel this all the time - whenever I sleep with someone new, whenever I'm at a beach and I'm supposed to take my shirt off.
"But I'm not going to be ashamed of who I am, not anymore."
Diaz has launched a GoFundMe page asking for donations to pay for skin removal surgery which he estimates will cost around $20,000 (£12,600).

"I can't believe how much attention this has gotten in the last hour or so.," Diaz writes on the page. "You all are so incredible."
