The 21-year-old has revealed that head coach Thomas Christiansen, who was appointed in his role in the summer of 2017, had slimmed him down.
“I feel like I’ve improved a lot,” Phillips told The Yorkshire Evening Post. “Physically I’m quite big so I’ve got quite a bit of body fat. He (Christiansen) tried to make me slim down so I could be quicker and a little bit sharper.
“It’s hard because you love a chocolate cake after Sunday dinner but you’ve got to nip these things in the bud. I’ve started eating a lot healthier.
“In the first couple of weeks I felt a bit drained but by cutting down on certain things I’ve felt the benefit. You can see that in my performances.”
It is quite an astonishing revelation from Phillips, and one that shows just how important it is for professional footballers to stay in shape and keep fit.
It is also great that Christiansen has noticed this in the 21-year-old, and that measures have been taken to sort it.
The central midfielder is an important player for Leeds, and him staying fit and healthy will be important for the Whites as the season progresses.
Phillips has scored five goals and provided one assist in 15 Championship appearances for Leeds so far this season.
The Whites will take on Middlesbrough at Elland Road in the Championship on Sunday afternoon.
