The unexpected new male models: they're plus-size.

Body-positivity isn’t just something women struggle with, it also affects men. Obviously women most feel the pinch of narrow beauty standards but more and more, men and boys are suffering too.

A quarter of Australian men who fall inside a healthy weight range think they’re fat, a statistic mirrored by the quarter of young men who last year rated “body image” as one of their major concerns.

Fad diets, eating disorders, and steroid abuse are all on the rise and until we do something about an industry now thriving on making men hate themselves, it’s only going to get worse.

Yes, body image is a female problem but it’s not just a female problem. In the same way women benefit from seeing other women who actually look like them, so do men.

Hardly any major clothing brands make plus-sized menswear and those that do barely advertise them. The plus-sized market for men is estimated to be a $17.5 billion a year industry, so wear are all the plus-sized male models?

Well, we found a couple, as well as a few other trailblazer’s of the men’s body positivity movement…

1. Zach Miko.

Zach Miko is the first plus-sized male model ever signed to a major agency. At 6ft 6in with 40in waist, he started out modelling for target but now works for IMG, the agency that looks after models like Freja Beha and Gigi Hadid.

"There has been a lot of support in women’s modelling -- models such as Ashley Graham and Tess Holliday have been making huge waves," he told the Guardian in a recent interview.

"Seeing someone [like Graham], who would normally be shunned, was awesome. I always had my own body-image struggle. With men, there is still a lot of bravado and false masculinity to get through."

2. Bruce Sturgell.

Much like in the women's fashion world, men's plus-sized bloggers are helping to increase visibility, promote body love and dole out straight-up hot fashion tips for larger men.

Bruce Sturgell operates Chubstr a blog and "style destination for men of many sizes", teaching men how to own their personal style no matter what size they are.

"I think that if you want to affect change, you have to show the industry that there is money to be made in this space, and that there’s a lot of good will," Sturgell told DigiDay.

"From a brand perspective, not only is featuring size diversity, different types of models and great fitting clothing important, but knowing that people will buy it and they want it and have the disposable income to buy this.

"I'm short and wide. I want to see someone that looks awesome wearing these clothes in my size. Seeing that is aspirational."

He started it after an unpleasant fashion experience "left a bad taste in my mouth", he explains on his site, "ever since then I have vowed to never feel that insecure or ashamed of my size again."

He's also involved in Tess Holiday's #EFFYOURBEAUTYSTANDARDS campaign.

5. Matt Diaz.

Finally, there's Matt Diaz who became an advocate for body positivity after posting a video about his dramatic weight loss online.

"Whenever I sleep with someone new, whenever I’m at somewhere -- at the beach or something -- and I'm supposed to take my shirt off, I can’t," he said in the emotional video.

"I think it's important that we learn to love the bodies we're in, even if we don't necessarily like every little thing about them."

He's come a long way since then and his popular Instagram has more than 19,000 followers.
