Osher Gunsberg shares his first shirtless magazine cover and said he is "7 months off meds."

Osher Gunsberg always promised he would never take his shirt off on camera, unless it was for the cover of Men’s Health magazine.

And he’s a man of his word.

The Bachelor host will appear on the September issue of Men’s Health magazine and has shared a first look of the cover to his Instagram account.  

More importantly, in the pages of the magazine he will talk about the physical and mental health transformation he has experienced over the past year.

Under the careful guidance of his GP, his psychiatrist and his personal trainers, Gunsberg has lost nine kilograms of fat and gained two kilograms of muscle.

He has also completely stopped taking the medication he was dependent on to manage his Obsessive Compulsive Disorder (OCD).

“I started this #MHtransformation as a way to help me manage life off of meds. I hadn’t been on antipsychotics for about 18 months before I started this,” the podcast host wrote on Instagram.

“I’d shifted to a different medication for the OCD, however as I got better and better, the side effects now became more prominent than the symptoms – so me and my Dr decided to try life without them.

“Coming off meds in Dec meant that I needed to put management strategies in the place where they once were, I needed things to help me regulate my emotions and emotional responses – and resistance training was a large part of that.”

Gunsberg went on to explain that he pushed his body every day to release the feel-good hormones of “endorphins, dopamine, serotonin and norepinephrine”.

He also regularly checked in with his psychiatrist and his GP during the entire process.

“It’s now 7 months off meds, and I’m still under Dr’s supervision because there’s a difference between not taking meds and not NEEDING to take meds,” he explained.

“To keep it that way, resistance training is something I do almost every single day. I ride my bike almost every single day. I eat with purpose and consideration every single day.”

The 44-year-old said the mental health and physical health benefits of his new lifestyle regime are “off the charts”.

“And let’s be honest, the aesthetic benefits aren’t bad either,” he added.

Earlier this year, Gunsberg announced that he had written a book about his struggle with mental illness.

Titled Back, After the Break, a nod to his television career which has spanned two decades, Gunsberg shared a picture of the book’s cover on Instagram.

“I’m thrilled to reveal to you the cover of my first book,” he wrote.

“You mightn’t know that for a lot of the time you’ve known me, I’ve been managing life with mental illness.

“I wanted to talk about how with the help of some great doctors, a great mentor and my love wife Audrey Griffen that I managed to recover from the depths of psychosis to having a life that is a long way from how bad things were, because I know I’m not alone in going through what I went through,” the television and radio presenter shared.

In 2017, Gunsberg, a director for SANE Australia, revealed he had suffered from depression for a number of years, as well as social anxiety and obsessive compulsive disorder.
