Although we have the best of intentions, the weight can creep on.
This is a battle Jason Manford is all too familar with.
Taking a seat on Lorraine's couch, he explained just how hard he's battled with his weight and self-image.
The 37-year-old bravely opened up about his fear of posing topless on Instagram and added that he "doesn't feel good."
'We see the bloke playing Thor and we think: Is that what arms are supposed to look like?!' @JasonManford talks body confidence after recently sharing his own struggles with self-image online. #Lorraine pic.twitter.com/pJTzVSGh3K— Lorraine (@lorraine) November 23, 2018
However, the dad-of-five is trying to make better changes to improve his health and lifestyle.
Nevertheless, a topless photo did appear on screen as the host of the ITV show said: "You've spoken about yoyo diets as we all do, I think you look gorgeous."
Jason quickly responded by apologising to viewers: "Sorry everybody if you're having your breakfast."
He explained how the topless photo made its way onto his Instagram in the first place.
"I got sent these lovely shorts and I really liked them. I never get sent stuff. The company said, 'Can you do a post with them on?' And I kept putting it off. In the end I thought, 'Yeah fine'," he said.
However when it came time to follow through and throw up the snap, he put it off as he suffered from "self-loathing" and felt insecure with his "moobs" and "stretch marked skin."
But Jason did post the picture and opened up to his followers about the struggles and his unhappy days he has with his body.
In the Instagram caption he said: "Here it is. I got sent these amazing James Bond shorts by the brilliant folks at @orlebarbrown and all they wanted for it was a picture on my social media. Absolutely bargain I thought as someone who never ever does that sorta thing.
"But then I realised that I had forgotten I was fat and not the most photogenic especially in a pair of swimmers!"
"The good folks at @orlebarbrown waited many weeks before politely enquiring ‘would you be able to do a post’ but my own self-loathing and embarrassment about my body stopped me and made me break my promise with them."
"Then today, I just thought ‘sod it!’. Yeah I’m overweight, I try and train at the gym, I know what to eat and what not to eat, I fluctuate, I’m trying, I’m struggling, I have unhappy days about my body and I have days when I forget but I never have good days," he said.
"I’m not a good advert for clothes but I’m a good comedian and I’m a good dad and I’m trying my best to be good at everything else too. I need to remember my own advice, ‘Just because You’re struggling, it doesn’t mean you’re failing’, he added.
He finished the candid post with: "Anyway, not many people would turn a pair of free swim shorts, no matter how nice they were, into a soul searching session but sod it, that’s me. With my moobs and my stretch marked skin and my cavernous belly button! At least I’m nice."
We couldn't agree more with Jason, you aren't failing because you're struggling and it's a reminder that men have insecurities over their body image too.
Jason is a busy dad to eight-year-old twin girls, a six-year-old daughter, a five-year-old boy and three-year-old girl.
