Tyson Fury has his licence back and is healthily moving closer to returning to the ring.

"The Gypsy King" has not fought since November 2015, when he won a heavyweight title fight against Wladimir Klitschko.

Fury is now on the road to coming back to action and is facing a familiar issue - excess weight.

That is why he is now working with nutritionist Greg Marriott, who gives answers to some interesting questions one may have over Fury's road to return.

Asked about how much weight has Fury already lost, Marriott explains, as per Sky Sports.

"Nearly four stone. But it's not just about the weight, you have to be mentally right as well. A happy fighter is a dangerous fighter.

"He's not training hard while he's heavy because he's prone to injury, so he's doing low intensity stuff and managing his diet. He's breaking into training easily. It's about how he feels."

What about the calories he is consuming?

"Tyson is on seven meals per day. In the morning he'll have low-carb rye bread, avocado, eggs and lean bacon. No sugars, like tomatoes.

"He's on 3,500 per day. When you try to cut weight (without enough calories) then you hit the wall, and you fatigue.

"Tyson needs to be on 3,500 calories a day but, when he's expending 2,000 calories in the gym, he will need to be on 5,500 calories a day."

For those who wonder what is Fury's diet like, Marriott explains.

"Tyson is on a ketogenic diet. A ketogenic diet consists of high fats, minimal carbohydrates, and some protein."

But, is Fury really disciplined on it.

"Tyson finds it hard. We gave him a taster of this before Christmas, but, now he's training in Marbella, he's being really strict."

If it gives enough power for Fury's training, Marriott is positive.

"He's on a 'targeted keto' diet so we know exactly how much carbohydrates to give him. When he's done an hour's session, the carbohydrate is out of his body, he utilises a different fuel source which burns fat."

It is also interesting how big Tyson Fury will we see in his next fight.

"Tyson wants to be 18-and-a-half stone. It's not about being the bigger man, it's a fitness game. To put on the show that Tyson wants, you have to be light so you can move for 12 rounds," Marriott explains.

Can Fury be as fit as he was against Klitschko again?

"Yes. He got below 18 stone doing everything wrong. If he listens to me, he can get below 18 stone again. Rome wasn't built in a day but it is definitely achievable."

And finally... What meal Fury enjoys the most?

"Fish and chips, but who doesn't? Tyson, if he sticks to the plan, will be allowed treats. If you do this diet right, you can have a cheat meal. But you can't do that every weekend!

"Tyson will be getting a few good meals, trust me. Everyone thinks dieting is doom and gloom and you can't eat anything but, the way I work, you can. You need to feed the mind, and you need a healthy mind before you fight."
