Tyson Fury has never had a healthy lifestyle and I've never seen ripped Fury after all but there was a time when he tried and still he looked chubby because he has a lot of subcutaneous fat and it's very hard to get rid of it, plus, as far as I remember, he said he isn't that disciplined and can't say no to tasty foods. To summarize, he doesn't want to put the effort to lose weight and get ripped because it brings absolutely zero value to him and he is not a person who cares about looks. So, he eats whatever he wants and has fun.
The fact is, he beats people, he beats everyone, he beats people who dedicate their life to training and diet, who constantly look at numbers on computers to check their conditions and every statistics.
Tyson Fury is a pure talent. In the world of sport, there are talents and athletes. Talents don't need to train much and eat limited, they are naturally talented, their body and mind is built for the sport they compete in. But athletes, they are just average humans who want to become successful in certain sport and they train all the time and follow diet to get as good result as possible. And there are a lot of examples of that in every sport, like in football, we know that Messi is a talent and Ronaldo is an athlete.
Well, after the fight he will likely do and eat a burger for sure just like what he did with his fight with Dillian Whyte he also gave Dillian Whyte a burger which Whyte said he couldn't eat because he got bad teeth that were destroyed during the fight so for sure it was a terrible idea for Tyson Fury in getting Whyte to eat his favorite, but for sure it was how Tyson Fury just do things he will likely train hard but his body fat is still likely there, well I don't really want to body shame at all that is why,
He might just think of how good is he even if he didn't do something about his weight, The dude still has the power to knockout heavyweights and that's all he needs since he already proved it against Wilder thrice. Now that he looks heavier than before, I don't think he will be that serious when he fights Ngannou because he is full of himself and thinks the guy is an easy fight. well! we can't really understand how Fury thinks since he always finds his way to win every fight. let's just see how will it turn out this time.
For sure every boxer has an imprint that they will likely still be good with the boxing department even though he is not that fitted to fight, his movement and brain have likely remembered most of the moves he previously had, so even though Tyson Fury is not fit to fight he would likely still got a chance that he will knockout every boxing fighter for sure,
