Big John Fisher reveals tragic reason for his weight gain after family loss

Romford's 'Big John' Fisher opens up on weight gain after heartbreaking family loss.

Social media star John Fisher, known to millions as 'Big John' for his catchphrase "Bosh!" and his love of Chinese takeaways, has revealed a deeply personal reason behind his weight gain.

Appearing on Good Morning Britain on November 5, 2026, the father of boxer Johnny Fisher spoke with host Kate Garraway about a new documentary series on Paramount+ that follows the Fisher family.

The show offers an unfiltered look into their lives, including the laughter, the tears, and the difficult moments that rarely make it onto social media.

Garraway directly asked John about the serious side of his weight gain, noting that fans have long warmed to his jokes about food but that there was clearly something deeper beneath the surface.

John did not shy away from the question.

He explained that he had been an active man in his youth — boxing as an amateur and playing football at a high level — but that everything changed after his father passed away.

"When my dad passed away, I found solace in eating," he said.

His father was not just a parent but a close working partner and a confidant.

"The only time we had a lot of stress with work and money, and when your dad is no longer there — someone you've worked with all your life and is your confidant — when he's no longer there, I found solace in food," John added.

He was careful to frame his explanation as a reason, not an excuse.

"It's not an excuse, but it's a reason why I put so much weight on," he said.

One of the most striking parts of his admission was that he did not fully notice the change as it was happening.

"The thing is, you don't realise you're putting the weight on as well, you still think you're the same person but you're not," he said.

The interview also revealed that John has been working with former World's Strongest Man Eddie Hall to turn his health around.

John confirmed that he has lost approximately seven stone — about 98 pounds — over the past year with Hall's help.

The weight loss journey is documented in the new Paramount+ series.

Hall delivered a stark warning that became a turning point.

"He said to me, 'John, if you don't lose weight in two years, you'll be dead,'" John recalled.

John acknowledged that he is still overweight and has a long way to go, but he emphasized that he was "a lot bigger" before starting the journey.

The documentary series captures both the physical transformation and the emotional process behind it.

Viewers who tuned into Good Morning Britain responded with an outpouring of support on social media.

One fan wrote: "After you mentioned your loss of father... my sincere condolences, John … look at you now in a different light."

Another viewer said: "Was great to see big John on TV, lovely guy and great family he has to. Bosh."

A third added: "Good to see big John losing stones."

The Fisher family's new series on Paramount+ is described as offering never-before-seen access into their home and daily lives.

John Fisher first went viral for his larger-than-life personality and his signature catchphrase "Bosh!" which he would shout after finishing a meal, often a Chinese takeaway.

His son, Johnny Fisher, is a professional boxer with a growing following in the sport.

The family has built a significant online presence, but the documentary marks a shift toward more personal storytelling.

In the interview, John reflected on the difference between his younger, fitter self and the man he became after his father's death.

"Listen, I'm still a big man now but I used to be a fit man," he said.

"I used to box as an amateur and play football at a high level, but I was always fit when I was a young man."

The loss of his father created a void that food helped fill, even as his health suffered.

Grief, stress over work, and financial pressures all contributed to a cycle that he now says he did not fully see while living through it.

The documentary on Paramount+ reportedly shows the full arc of this story, from the weight gain to the intervention by Eddie Hall to the ongoing effort to lose weight.

Eddie Hall, who won the World's Strongest Man title in 2017, has become known for his own dramatic body transformation after retiring from strongman competition.

Hall's warning to John was blunt and direct.

John repeated the message during the interview: if he did not lose weight within two years, the consequence would be death.

That warning appears to have been a catalyst for change.

John said the weight loss has taken about a year so far, and he credited Hall with helping him make progress.

The documentary captures this process in real time, showing both the setbacks and the victories.

For fans who have followed the Fisher family online, the new series offers a side of Big John that the catchphrases and takeaway videos never revealed.

The interview on Good Morning Britain was part of the promotional tour for the Paramount+ series.

Kate Garraway, who has been open about her own experiences with grief and health struggles, drew out the emotional core of John's story during the conversation.

She pointed out that while audiences love John for his humor, there was a serious story behind the jokes.

John agreed and did not hide the pain behind his public persona.

The seven stone weight loss is a significant milestone, but John made clear that the journey is not over.

"I'm still overweight; I've got a long way to go, but I was a lot bigger," he said.
